Intro:
Firstly I would like to thank Lark Studios for organising this tour in conjunction with Audio Concierge for the opportunity to be able to listen to these in the comfort of my own living room for ten days to put them through their paces and let me give my impressions on the Lark Studio LSX Universal IEM.
It’s been a while since I’ve done a review on Head-fi as it has been a busy year for me in general but when this opportunity arose and worked out I would be off over the Christmas period to give them the time they deserved to listen to them in depth I thought why not?
I’ll be honest in saying I had not heard of Lark IEM’s until this came about so was going to be an unknown quantity to myself as usually in the past most of the items I would review I already had an interest or curiosity about that said item in what it sounded like as had already known about the product but yet the Lark was an unknown to me or what specie of in sound these IEMS actually were.
I’ll be honest from the outset and say I have tried a few IEMs in the past year or so as I have been looking for a potential replacement flagship for my JH16’s and I know I can’t quite afford the mouth-watering but as equally stunning sound of the JH Layla’s or the stunning Obravo £3K+ range to date.
I had heard plenty of others ranging from the £1-3K mark and I am finding as good as many of them sound they are just missing that X factor in the sound for me or sounding a bit too similar to each other at times and I am referring to the IEMs that are in the realms of a 65-75 inch 4K OLED panel!
I currently am using now as my main go to IEM the Vibro Labs Maya which went largely under the radar to a degree which was tuned by Luke Pighetti who sadly is not in this game anymore which just shows how competitive this market is now days and is more busy than ever the domain of IEMs whether Universal or custom fit.
The Maya is a quad BA driver Maya that strikes the cord in the signature that I fell in love with when I reviewed them a couple of years ago and ended up buying a set which cost $599 when they was out and for me has given a lot of good IEMS up to the £1K mark a run for their money so I was finding it hard to find something to takes it’s mantle so to speak in my eyes especially in the mids with the Mayas deft but exquisite mid detail retrieval despite the Maya fit been one of the more awkward I have ever encountered in a universal IEM using the bigger 600 comply bore tip size really lets it down and wished now I had it turned into custom when I had the chance by Luke.
So for me at the moment it has been about finding a flagship IEM that could replace my beloved Maya sig whilst improving on it technically without costing the astronomical amounts flagships have moved to as their ceiling price last few years whilst currently I am on a more austerity budget in this hobby to what I used to be whilst my good wife starts up a new business from scratch after redundancy so for now I cannot think of stretching to the “super £2.5+ iems” of this world for now.
Build & design:
The pair I had for review was as can be seen in photos is a black looking face plate finish with the LS branding on one plate and the Lark bird logo on the other side with a smoke transparent shell so was not able to see that well at any of the driver workings which is a shame yet from what I could see it had a good finish to the casing and the supplied standard copper cable is very pliable and non-microphonic with a standard straight 3.5SE plug and 2 pin fit for the earphone end. One of the unique selling points that will be tempting is Lark do not charge for artwork on their iems.
Size and fitment:
The shell on this universal LSX on first inspection thought they looked maybe a bit big and maybe cumbersome considering it has to house 10 drivers somehow into each ear and bearing in mind everyone’s ears are different it will always be your mileage will vary depending on your ear shape.
I happen to have small ears, so I was told by my Audiologist when I had my first ever ear impressions done for my JH16’s back in the day but the Larks actually fitted in my ears quite well without sticking out or feeling awkward to fit in and most importantly felt comfortable over long listening sessions staying anchored in pretty well even though it doesn’t feel like it takes much for them to just slot in the ear compared to some other IEMs which can be more time consuming to twist and fit in just in the magic perfect place.
Supplied accessories;
The Larks come packaged in a hard sturdy presentation box with the LSX IEMS and the accessories laid out in the laser cut foam cut out sections.
The LSX comes bundled a plenty with accessories:
Comply/ Spin fit tip pack of multiple sizes and both foam and silicone tips.
Leather carry pouch/ bag
6.5mm adaptor
Plane attenuator adaptor
Cable strap
Amp/ dap band (they refer to it as a sports bracelet?)
Cleaning brush with ear hooks
Lark Studios embossed Cleaning cloth
VIP owner’s card
Only thing for me here which does gripe at me a bit and couldn’t ignore in the end… as sturdy as a job it is doing is the packaging, storage box design and storage pouch supplied with the presentation case red foam cut out for everything it seems out of place, almost dated in design and more like an old jewellery box which I know some far eastern companies in the past have been a bit eccentric with their style and design which is very reminiscent to this Lark offering here also when it comes to the storage box & travel storage pouch.
For example the supplied drawstring pouch is not a suitable for on the go storage solution to protect a $1700 IEM and feels more like a token gesture as I do wonder how many people will use this pouch for its intended purpose?.
For me the overall design and packaging does not reflect the quality of the IEMs themselves and now been familiar with the Lark build and sound quality think a package that encompassed the design styling of say the way Oppo, Meze or RHA or even Flare manage with their design on mid entry products and packaging of their products goes a long way to helping the perception and over all eye to detail of a company’s overall cohesion of a product from conception to finished article which would be icing on the cake if they could give the overall product a more classy and sophisticated modern approach with a travel storage solution that has purpose to protect the said IEM’s when we are still talking above $1600 for a flagship IEM.
I know the company is starting in its formative years as a new company on the block and hopefully in time they will be able to evolve the level of design and imagination on the packaging and travel case storage ideas as the company grows bigger with popularity and sales.
Sound:
Not knowing at all what Lark’s values were on the sonic side in terms of sound signature I must admit I had some trepidation on what the tuning of the LSX was going to be like as to start with I have sensitivity with treble with overly bright/ harsh IEMs on the top end plus I am not a fan of having the mids sucked out so the treble and bass dominates too much the overall zen balance of an IEM.
In the first minute of putting the LSX in my ears they immediately aligned any fears I had of getting an aggressively harsh over bright or sibilant treble or sucked out mid-range tuned IEM. My first actual worry if any from my first brief encounters on listening with the LSX actually; was the bass going to be too dominating over the rest of the sound spectrum?... Scroll down to bass header for that more elaborated answer.
It becomes quite evident very quickly with these IEMS they are going to be just as easy to listen to as they are with the very efficient 20ohms it takes to drive these 10 driver IEMS.
The LSX sound is one of gliding smooth velvet with rich deep resolving bass lines, non-offending extending highs and a minefield of details in the mids to die for with good level of tonality across the board.
The Larks never sound like they are struggling to deliver the music to you, it has an uncanny knack of making it all seem free flowing organic analogue feel to the sound the LSX offers which makes these IEMS quite easy to find good synergy with other equipment regardless of their signature which in turn also makes these a better IEM for all those poor recordings out there that are over harsh due to the LSX signature. Although a poor recording will still be obvious to hear the LSX has a forgiving nature with the smoothness and finesse in the manner the treble handled by Larks tuning makes any harsh or hard recording sound more bearable than normal but it still won’t hide the shortcomings of a poorly mastered recording in general.
Treble 3 BA Drivers; (2 BA drivers & 1 x Super tweeter BA driver)
Some treble tuning even on a flagship IEM can sometimes be almost trying too hard in been over resolving and become detached from the rest of the music like a separate entity that distracts your mind and becomes an irritation taking away concentration on the overall balance of anything that may be happening with the all essential mids or even bass areas.
With the treble on the LSX it is delivered by two treble BA drivers and one super tweeter BA driver allowing treble notes to extend past any of our hearing thresholds yet does it with smoothness and good full bodied texture to the finer treble details
The lower and mid treble notes on the LSX manage to knit into the mid-range part of the music with good cohesion which doesn’t give that detached feeling when listening to the treble range.
Some might say it is a rolled off or rounded off to be a non-offending treble but this IEM treble still has that airiness and smoothness whilst having that shimmer and lively energy with trailing edges to symbols and hi- hats in the extension decaying well when the treble note arises above the rest of the frequencies in the mix.
This allows the treble to never be lost in the mids and the super tweeter allows the treble extension to rise above everything to the higher frequencies when the recording requires it giving that top end giving it that more feel of openness and a natural ability for the highest notes to become more prominent to hear in delivery and decay more precisely yet does this without ever wanting to sound like someone putting their nails down the blackboard due to the silky liquid smoothness of the treble tuning.
Instead the gently smooth sweet sounding treble notes blend in with the mids and bass on an even kilter making listening sessions a pleasant experience with still been able to enjoy the intensity of those higher frequencies when they happen yet because the LSX has room for instruments to breath you just naturally hear those treble notes shine through the overall mix of the mids instead of you having to concentrate on finding those notes making it more naturally relaxing sounding and not that tuned type of flagship IEM that is trying to scream look at me I am your analytical high detailed thinned out treble that wants to use razor blades in your ears to make it’s point.
Mids; (4 x BA drivers)
The Lark's mids are definitely the engine house of these LSX with its four drivers syncing very well with a vast amount of detail with a full bodied rich dynamic versatile mids which you would think is a given for a flagship IEM that has four drivers delivering the core information yet it does it with a flexibility and subtlety and clarity you hear the fine timbres of instruments are projected with clarity and deft vibrancy and energy to each note attack.
Coupled with a good noise floor on the LSX which these very efficient IEMs never showed any hiss with the equipment I tried it with is what helps it give it still enough room to breathe in the space it has to work in and keep good clarity with a soundstage that is maybe not the largest I have heard on an IEM but it is still competent enough at this level as I think due to the LSX getting the balance so right in many other areas this never becomes a factor unless of course you are a diehard Sennheiser HD800 fan who craves that dizzying vast soundstage to show of the imaging in an IEM also.
The LSX’s characteristic is actually a fairly intimate closer feeling sound which makes you feel very close to the band performing so much so it feels like at times you are in there with them pretty much instead of the performance in front of you.
Some may prefer it as if you was sitting further back in an auditorium feel or the soundstage was huge but I personally love this type of delivery in the mid-section and although it is an intimate feel the LSX still somehow manages to feel spacious enough to have room around the notes to breath due to the way the depth and headroom Is dialled in on the LSX.
The Lark IEMS even though as mentioned above with the close intimate sound has a very accomplished imaging which is accurately pin point and fast which was one of the straits of this IEM that impressed me a lot which also helps with this IEM feel like they still have a good sense of air between each note due to the accuracy in timing with the imaging.
Timbre is one of the corner stones that makes this IEM shine with the ability to do subtle micro detail with trailing edges on Violins or acoustic guitars you could hear those small changes in the string vibrations of the note decaying with ease due to both that closeness to the music I mentioned earlier.
The perfect timing with the start- stopping of notes making string frets really resonate with the note changes with any type of guitar on the LSX with help of the super tweeter kick in with its liquidity on the higher string notes which making these LSX so non fatiguing to listen to.
Vocals have good tonality, clarity and placement in the soundstage with the low floor noise the vocals stand out without ever been overbearing or shouty.
I would normally point out which vocals in particular an IEM shines with and doesn’t yet any vocalist sounds full bodied and powerful without spiking or booming whilst been able to showcase the versatility of been supple finer details with delicate vocals to the aggressive upper mid-range & treble edge of grainy rock vocals styles just adds to the fluidity of the mid-range naturalness in tonality coming through.
Like the overall soundstage vocals feels fairly intimate and I must admit I am one who prefers the feeling like I am front row with Tori Amos, Stevie Nicks, Gregory Porter, Adrea Bocelli…list goes on, yet given the cosiness with vocals on the Lark’s they always seem to have plenty of separation and headroom to work in and breath on their own in the mids as these IEMs just make you want to listen for another hour at a time with the LSX portraying the accurate vocal qualities tonally makes them very rewarding in this section.
Drums had the same ability as strings do with tonality to trans-fixate on the LSX with the rendering of each bass note impact been played as what it manages to pull off in the mid bass section here is how well the low mids are seamlessly in sync with the upper and sub bass section that there is no disconnect allowing for a more natural decay of instruments so with drums there is no hump or in the lower or higher mid bass frequencies here which I have known to ruin a good overall IEM that I owned in the past.
Considering the lush, smooth and warmer side of the LSX the piano also manages not to be coloured at all in tonality allowing most genres of music to stand out when a real piano is used with the good air and sparkle towards the top end of the key notes with flat notes having good resonance with subtle harmonic decay of strings depicting whether a key is been stroked softly comes through clearly or if a key is hit hard delivers good impact to the mid bass.
Sharp notes loudness rise to great effect in the upper mids helping tracks like fast blues piano playing come to life with good zest and dynamics.
Because of the impeccable timing and depth that the Larks possess it makes hearing the resonance and vibration in notes have feel as well as sound even on BA drivers it all adds to piano sounds having a soul on the LSX and not just a hard sounding dull note played each time.
The LSX is far from not trying to be the most analytical Flagship IEM on the planet and does not try anything other than a midrange that has a good focus on a smooth liquid detailed harmonics with mid bass notes allows for a natural layering of continuous decay of the note through to the lower bass floor.
Even though this IEM has a moderate staggered V shape the mids work flawlessly with the sub bass region does help a lot towards making this IEM have that feel of having a consistent balance in the bass response but also over-all balance to spectrum when you are listening to them as even though the LSX is not tuned flat/ neutral it has just the right balance of tonality, timbre and timing to make these sound organic analogue heaven to listen to with most genres I tried (Classical, Rock ,Dance, Pop, Metal, Jazz, Blues, acoustic, live recordings) making this quite a flexible sounding IEM.
It’s hard for me not to say the mids really are the jewel in the crown that shines on these Larks, not that this makes them any more dominant in any way to the lows or high area qualities this IEM possesses, just the mids are very accomplished because they are so harmonious with the lows and highs is what gives the LSX such a natural balanced feel to the signature when listening to them.
Bass (3 x BA drivers)
Bass will always be a decisive factor in choosing an IEM just in terms of the quantity of bass we each personally prefer from a light weight sub bass or a heavy sub bass on the bottom end and there will always be those that want a more studio monitor neutral flat response or those who want Rob D’s Clubbed to Death bass hit you as hard as been surrounded by 400 watt speakers in a night club.
Yet with the three drivers on bass duties the LSX provides a smooth bass transition through the range with a good tight powerfully weighted kick in the lower mid bass which decays well through the lower frequency range with good control and depth without ever losing control. The LSX may not be the tightest ever bass around out there but it has enough grip and control that a bass hit never sounding bloated or soft with any songs I heard.
The LSX is on the right side of a rich deep dynamic bass without been over rich which I think hits the right balance of having enough bass which would reflect how low you would realistically hear a drum kick go in a live environment for example without been over accentuated falsely. This falls between both true bass heads or neutral flat bass response perfectionists and those who like a bit of added bass that won’t over running & ruining rest of the sound spectrum.
The devil is in the detail as well as the quantity of the bass and from the mids to the lows in a bass note is helped by the clear transients which help differentiate the types of bass notes been played. The lowest bass notes attack and impact it gives feels upfront with the rest of the music yet the reverb and decay of the bass note falling away into that black background can still be visceral in feel below 60hz which is always welcome in a BA driver layering it more behind upper bass note impacts giving the bass a healthy field of depth from the mid to low bass region which is great for rock, blues or jazz music especially.
Somehow it seems Lark Studios have paid as much attention as everything else on this IEM to getting just the right balance for it to blend in to the mix without been overbearing into the mids and stops before becoming too heavy or over bloated with songs.
In all a very good high quality tuned bass that suits any genre well due to its well-controlled tuning and smooth consistent manner that can still have good impact in the right places to give it slam when needed yet maintain subtleness when needed with the detail rendering through the fine timbre showcased on these Lark IEM’s.
Comparisons with the equipment used;
I found no matter what source or set up I tried during my time with the LSX it shone and performed to a high standard and had good scalability when going from say a DAP to a dedicated Headphone amp, it was more just a question which one did it shine with the most & least?....
With the Sony WM1A Walkman the LSX soundstage was made to feel more spatial whilst the Sony’s now more balanced airy detailed mids since a major update last year really shows off the Lark’s resolving mid-range ability with clarity and the now more linear tighter bass on the Sony gives a synergy that makes them an ideal pairing with the LSX’s.
It was a similar story with the Onkyo DP-S1 just the SX1 sounded a bit more neutral and brighter in the upper mids with a more attacking emphasis on the mid bass to the Sony whilst still sounding balanced as the DP-S1 more direct lively approach mirrored the warmer smooth nature of the Lark’s signature to great effect. Vocals really stood out with an air and height to a singers range like it had no ceiling felt like vocals on the LSX was the focused driving force that carried the Onkyo to have a good transparency and tempo.
A third different sounding dap in the newer A&K AR15 A&Norma which feels like it has gone back to the more old school smoother A&K sound compared to its predecessor the more funky sounding dynamic A&K 70 mrkii yet the LSX is still at home enough with the AR15 with the clarity of the mids on both the AR15 & Larks been able to capture the subtle details and reveals a good openness with the top end having a noticeable sparkle yet a certain amount of the natural smoothness the A&K provides without both been over bearing in warmth or richness.
I found with all three daps I tried the LSX they all paired well despite all been different sounding daps albeit they seem to step up in warmth with the Onkyo been more dynamic/ bright, the Sony been richer with still a moderate amount of warmth since the f/w update in 2018 and the A&K has warmth with smoothness.
If it was the Sony before it had the major fw update taking it from super warm and rich with it's boomier sub bass I highly wonder if it would have been too much together with the LSX’s but with the new fw update been more refined, linear and airy than previously with this and the Onkyo’s sig make for an equally as good yet different pairing with the LSX and the AR15 although sounding enjoyable enough they were just missing the bit of life & dynamics missing with the Sony & Onkyo players brought to the LSX with the right balance to counteract the smooth richness the Lark’s have to bring the best of both worlds together.
With amps/ dacs:
Moving on from daps running the LSX through a Pioneer U-05 Dac headphone amp and a Sennheiser HDVD800 Dac headphone amp showed even though the Larks are a very efficient IEM they scaled up really well with a nice big desktop amp and again like the daps it was very adaptable to both the opposite scales of sound signatures the Pioneer and Senn amp/ dacs operated at.
The LSX loves the extra currents on tap of these desktop amps yet managed to still sound quite on the noise floor on both amps which just helped the LSX feel like it had more depth & headroom to play with than it did on the daps which was nothing to complain about to start with but again was noticeable if for example I added the very underrated high quality Vorzuge Pure portable amp to the daps via line out just goes to show what extra you can still get out of these tiny micro drivers with good high quality amping.
The only down side I could find from a signature source with the LSX if the source bass was a bit softer or warmer with the likes of the Senn amp or a Chord Mojo the LSX would still enjoyable enough to listen with but was evidently noticeable when I then paired with a more tighter linear controlled source like the Pioneer U-05 or Vorzuge Pure amps that add that extra tightness controlled attack and neutrality with more headroom and airiness or brightness that counteracts the Larks more lush approach have that same effect the Onkyo or Sony daps did paired with the LSX.
The Chord Mojo pair’s fine with the LSX but the warmth of and the lushness of bot the Mojo & LSX might be a bit too much for some looking to strike that balance of the LSX smooth lush side but not overdo it. But if I was to pair the Vorzuge Pure with the Mojo the story changes on the cleaner signal and power tightens it all up with added weight and extension giving a less softer fuzzy lush approach to the LSX’s so they shine at just the right balance without sounding too soft and dark.
With the Pioneer U-05 coming from the same stable it is very much same type of signature to the Onkyo DP-S1 DAP but with a bigger better amplifier and running with a XLR balanced really gave the LSX a more expansive projection with and headroom scaled it up another level on the smile-o-meter with the LSX.
The last piece of equipment I had to try the Larks with was the Mojos older and now newer brother in the Hugo2 which before plugging It in I knew how much improved the H2 is to the original Hugo making it more versatile, further controlled and nimble than ever with anything that now gets hooked up with it due to its vastly improved voltage section, yet until you hear it you still do not know how these things will inevitably might pair up.
Despite knowing how good both the H2 and the Lark’s are it was a bit like hitting the jackpot as the analogue wizardry of the Hugo 2 analogue sounding dac and balance between aggressive and passive aggressive it can walk draws out the full tonality, dynamics, depth and detail these Larks have to offer and combines the power of the amp to deliver plenty of body and resolution to every note played (especially noticed with vocals here) yet somehow find even more calm and space for the music to be delivered to the LSX drivers made it an all-round performer to the highest standards with Hugo2 driving the LSX.
On the cable front the only thing left for me to try which would of been nice to compare which was unfortunately not available was the PW audio Saladin cable that Lark offer as an upgrade cable to see how much better the LSX could sound as the supplied universal cable only had a 3.5se plug thus not been able to try it in balanced mode in theory.
Alas I have a pure Silver custom made cable (to my spec) by a good fellow head-fier LEDZEP who only uses good quality silver solder on the connections and makes it to military spec literally and can hot swap balanced connections using mini XLR connectors. Up to now I had enjoyed the LSX with the supplied copper cable enough but the Silver cable takes it to another level of clarity and control of notes whilst also adding a slightly more neutrality to the signature just enough without taking away what is already the magic of the smooth, liquid detailed LSX sound.
I was then able to find out the also added benefits of running this now either balanced 2.5, 4.4 or XLR 4 pin so the LSX running in balanced, especially with the XLR balanced finds that extra bit of space and airiness in the soundstage whilst giving more controlled higher headroom with a desktop rig.
I have found some warmer sigs like the Larks in the past benefit staying with a copper cable ( i.e. Meze 99 classics for example) more than a silver just for the natural pairing for the timbre side of things but putting a pure silver cable on (even running in SE mode) gave it a further improved performance whilst still maintaining what makes the LSX foundations to its signature sound so great.
*Foot note on above sessions with using the supplied tips:
Like some IEMs out there may prefer foam tips sonically (like my Vibro lab Mayas do) I personally found that foam tips are a bit too stifling and muddying to the mids and treble compared to silicone tips which became obvious to me in like the first hour of using them I used with the LSX which came more apparent when using with the more neutral brighter sound of the Onkyo DP-S1 or Pioneer amp showed how much information was been subdued in the upper mids and treble so I ended up using the silicone Spin Fits in the end. (again like general ear fit of IEMS with tips YMMV)
Conclusion:
I’m not sure where to start really as from the word go these were easy to get on with and the natural fluidity and striking the right balance of warm with detail yet keep it still quite airy with space and clarity to breath enough whilst been dynamic delivering a natural timbre & tonal quality all round has made it hard to pick any holes in this IEM for those who appreciate dynamic, rich and smooth force of nature enjoying music which still is resolving due to the high amount of varying levels of detail which I have to say won me over quite quickly with me saying to the LSX’s at the end of my time with them “You had me at hello”!
Only negatives if anything on the sound would be for those ears out there that prefer your signature to be a neutral flat response only or a brighter treble sound or further still like it tuned above the 3db in the sub bass department or you prefer your IEM to have that vast big soundstage then I would say these might not be for you possibly but as one who appreciates and loves the In Ear Prophile 8’s as one of beter neutral IEMs I have heard or owning the bass hungry darker sounding JH16Pros I would say give them a try and they might surprise you how they pull you into the music with minimal effort.
That’s of course if you do not already own maybe a IEM like the gorgeous higher resolution JH Layla’s or Obravo master pieces with mind blowing natural visceral bass I have ever heard from a IEM which comes to mind, both of which are in the £2.5k + £3K + bracket to note.
The Lark LSX to me is simply a beautiful mid centric full sounding tonally organic IEM that strike a good all round balance that when paired with a livelier or brighter or less mirrored image of the LSX gets the best synergy and balance for these IEMS.
I even thought about the price which tugged at me a bit as the price to have customs is no more than the universal which then that initially sounds great from Lark considering they also charge no extra for artwork on either universal or CIEM plates that other CIEM manufacturers do but maybe the universal price could still be a bit lower to start with which I was thinking the latter and still do really as I think maybe $200 lower than the customs would be about right.
After ten glorious days with them and listening to plenty of other flagships out there ranging from £1K to £3K in the last year I would have to say I would actually still pay $1699 for the Universal as all I know is if I had the money at the moment I would of ordered a pair from Lark Studios by now which was only clarified for me by myself when I sent them back and consequently missed them greatly within the first day of not having them to hand.
Only other gripe personally as I am a bit of an overall package/ design & purpose for storage pouch, good as the LSX is on Sonic’s alone and the accessories supplied and packaging is solid enough I feel when you are getting a flagship IEM as both a customer and for the companies sakes from their POV they need a sharper eye in the design department to make them stand out a bit more from the crowd with a more modern and sophisticated presentation. The travel pouch or case needs to be more protective with purpose as also the overall packaging and brand design to reflect their high quality product in this very busy and competitive arena in the IEM business so hope it is maybe something that naturally will evolve and improve over time with the company growing with future success as they release more models.
Despite still not been completely perfect I found it hard to fault the overall sound partly as this happens to be my type of signature anyway so tried to do this without there been any signature bias, if anything I was probably harder on it as I know how I like this type of signature to sound from having my Vibro Lab Mayas at the moment (which after this I have to concede this is definitely another level up to the Mayas in most areas for the record!) but more importantly the LSX regardless of its signature managed to nail every one of the many departments like timing and harmonics in making music sound balanced, dynamic, clear and detailed in a enjoyable manner making the LSX fluidly cohesive and natural to listen to for hours at a time.
I know it feels like Lark is new on the scene to some including myself and is this maybe a case of flavour of the month some might ask as some IEMs can have a touch of that sometimes but all I know if you like what you hear from the LSX with their non-fatiguing sound these will last many moons more than just the latest flavour that passes into insignificant to the next big thing next month.
For me the LSX has the long term addiction to portraying music with detail with soul & emotion combined with deft and uncanny tonal performance could make this a cult legend over time sound wise alone as much as the Noble Kaiser 10 or another great 10 driver IEM by the same great man back in the day which have similar signatures.
To finally sign off I personally would give overall a 4.5 only for the fact I think the presentation/ design & quality with case & pouch could be better for the price as well as the universal price could still be a bit lower but for sound alone these Larks would get a 5 rating only for the fact I could not find much to fault when listening to them despite not been the widest soundstage or the tightest tuned bass out there (still above average though on bass) and that they pair easily with different sounding sources as I simply just could not get enough of listening to them in the ten days I had them.
I hope that going by this Lark Studios go from strength to strength going by this first outing from them so will be interesting to see if they can produce other models regardless of costing less or more than the LSX that they keep to the bar they have set for their house sound and principles in the LSX and produce good balanced liquid detailed IEMS that one can just enjoy the soul of the music rather than analyse with a microscope of concentration.
Good luck in this game for the future Lark studios in making more music loving IEM models…

Intro:
Firstly I would like to thank Lark Studios for organising this tour in conjunction with Audio Concierge for the opportunity to be able to listen to these in the comfort of my own living room for ten days to put them through their paces and let me give my impressions on the Lark Studio LSX Universal IEM.
It’s been a while since I’ve done a review on Head-fi as it has been a busy year for me in general but when this opportunity arose and worked out I would be off over the Christmas period to give them the time they deserved to listen to them in depth I thought why not?
I’ll be honest in saying I had not heard of Lark IEM’s until this came about so was going to be an unknown quantity to myself as usually in the past most of the items I would review I already had an interest or curiosity about that said item in what it sounded like as had already known about the product but yet the Lark was an unknown to me or what specie of in sound these IEMS actually were.
I’ll be honest from the outset and say I have tried a few IEMs in the past year or so as I have been looking for a potential replacement flagship for my JH16’s and I know I can’t quite afford the mouth-watering but as equally stunning sound of the JH Layla’s or the stunning Obravo £3K+ range to date.
I had heard plenty of others ranging from the £1-3K mark and I am finding as good as many of them sound they are just missing that X factor in the sound for me or sounding a bit too similar to each other at times and I am referring to the IEMs that are in the realms of a 65-75 inch 4K OLED panel!
I currently am using now as my main go to IEM the Vibro Labs Maya which went largely under the radar to a degree which was tuned by Luke Pighetti who sadly is not in this game anymore which just shows how competitive this market is now days and is more busy than ever the domain of IEMs whether Universal or custom fit.
The Maya is a quad BA driver Maya that strikes the cord in the signature that I fell in love with when I reviewed them a couple of years ago and ended up buying a set which cost $599 when they was out and for me has given a lot of good IEMS up to the £1K mark a run for their money so I was finding it hard to find something to takes it’s mantle so to speak in my eyes especially in the mids with the Mayas deft but exquisite mid detail retrieval despite the Maya fit been one of the more awkward I have ever encountered in a universal IEM using the bigger 600 comply bore tip size really lets it down and wished now I had it turned into custom when I had the chance by Luke.
So for me at the moment it has been about finding a flagship IEM that could replace my beloved Maya sig whilst improving on it technically without costing the astronomical amounts flagships have moved to as their ceiling price last few years whilst currently I am on a more austerity budget in this hobby to what I used to be whilst my good wife starts up a new business from scratch after redundancy so for now I cannot think of stretching to the “super £2.5+ iems” of this world for now.
Build & design:
The pair I had for review was as can be seen in photos is a black looking face plate finish with the LS branding on one plate and the Lark bird logo on the other side with a smoke transparent shell so was not able to see that well at any of the driver workings which is a shame yet from what I could see it had a good finish to the casing and the supplied standard copper cable is very pliable and non-microphonic with a standard straight 3.5SE plug and 2 pin fit for the earphone end. One of the unique selling points that will be tempting is Lark do not charge for artwork on their iems.
Size and fitment:
The shell on this universal LSX on first inspection thought they looked maybe a bit big and maybe cumbersome considering it has to house 10 drivers somehow into each ear and bearing in mind everyone’s ears are different it will always be your mileage will vary depending on your ear shape.
I happen to have small ears, so I was told by my Audiologist when I had my first ever ear impressions done for my JH16’s back in the day but the Larks actually fitted in my ears quite well without sticking out or feeling awkward to fit in and most importantly felt comfortable over long listening sessions staying anchored in pretty well even though it doesn’t feel like it takes much for them to just slot in the ear compared to some other IEMs which can be more time consuming to twist and fit in just in the magic perfect place.
Supplied accessories;
The Larks come packaged in a hard sturdy presentation box with the LSX IEMS and the accessories laid out in the laser cut foam cut out sections.
The LSX comes bundled a plenty with accessories:
Comply/ Spin fit tip pack of multiple sizes and both foam and silicone tips.
Leather carry pouch/ bag
6.5mm adaptor
Plane attenuator adaptor
Cable strap
Amp/ dap band (they refer to it as a sports bracelet?)
Cleaning brush with ear hooks
Lark Studios embossed Cleaning cloth
VIP owner’s card
Only thing for me here which does gripe at me a bit and couldn’t ignore in the end… as sturdy as a job it is doing is the packaging, storage box design and storage pouch supplied with the presentation case red foam cut out for everything it seems out of place, almost dated in design and more like an old jewellery box which I know some far eastern companies in the past have been a bit eccentric with their style and design which is very reminiscent to this Lark offering here also when it comes to the storage box & travel storage pouch.
For example the supplied drawstring pouch is not a suitable for on the go storage solution to protect a $1700 IEM and feels more like a token gesture as I do wonder how many people will use this pouch for its intended purpose?.
For me the overall design and packaging does not reflect the quality of the IEMs themselves and now been familiar with the Lark build and sound quality think a package that encompassed the design styling of say the way Oppo, Meze or RHA or even Flare manage with their design on mid entry products and packaging of their products goes a long way to helping the perception and over all eye to detail of a company’s overall cohesion of a product from conception to finished article which would be icing on the cake if they could give the overall product a more classy and sophisticated modern approach with a travel storage solution that has purpose to protect the said IEM’s when we are still talking above $1600 for a flagship IEM.
I know the company is starting in its formative years as a new company on the block and hopefully in time they will be able to evolve the level of design and imagination on the packaging and travel case storage ideas as the company grows bigger with popularity and sales.
Sound:
Not knowing at all what Lark’s values were on the sonic side in terms of sound signature I must admit I had some trepidation on what the tuning of the LSX was going to be like as to start with I have sensitivity with treble with overly bright/ harsh IEMs on the top end plus I am not a fan of having the mids sucked out so the treble and bass dominates too much the overall zen balance of an IEM.
In the first minute of putting the LSX in my ears they immediately aligned any fears I had of getting an aggressively harsh over bright or sibilant treble or sucked out mid-range tuned IEM. My first actual worry if any from my first brief encounters on listening with the LSX actually; was the bass going to be too dominating over the rest of the sound spectrum?... Scroll down to bass header for that more elaborated answer.
It becomes quite evident very quickly with these IEMS they are going to be just as easy to listen to as they are with the very efficient 20ohms it takes to drive these 10 driver IEMS.
The LSX sound is one of gliding smooth velvet with rich deep resolving bass lines, non-offending extending highs and a minefield of details in the mids to die for with good level of tonality across the board.
The Larks never sound like they are struggling to deliver the music to you, it has an uncanny knack of making it all seem free flowing organic analogue feel to the sound the LSX offers which makes these IEMS quite easy to find good synergy with other equipment regardless of their signature which in turn also makes these a better IEM for all those poor recordings out there that are over harsh due to the LSX signature. Although a poor recording will still be obvious to hear the LSX has a forgiving nature with the smoothness and finesse in the manner the treble handled by Larks tuning makes any harsh or hard recording sound more bearable than normal but it still won’t hide the shortcomings of a poorly mastered recording in general.
Treble 3 BA Drivers; (2 BA drivers & 1 x Super tweeter BA driver)
Some treble tuning even on a flagship IEM can sometimes be almost trying too hard in been over resolving and become detached from the rest of the music like a separate entity that distracts your mind and becomes an irritation taking away concentration on the overall balance of anything that may be happening with the all essential mids or even bass areas.
With the treble on the LSX it is delivered by two treble BA drivers and one super tweeter BA driver allowing treble notes to extend past any of our hearing thresholds yet does it with smoothness and good full bodied texture to the finer treble details
The lower and mid treble notes on the LSX manage to knit into the mid-range part of the music with good cohesion which doesn’t give that detached feeling when listening to the treble range.
Some might say it is a rolled off or rounded off to be a non-offending treble but this IEM treble still has that airiness and smoothness whilst having that shimmer and lively energy with trailing edges to symbols and hi- hats in the extension decaying well when the treble note arises above the rest of the frequencies in the mix.
This allows the treble to never be lost in the mids and the super tweeter allows the treble extension to rise above everything to the higher frequencies when the recording requires it giving that top end giving it that more feel of openness and a natural ability for the highest notes to become more prominent to hear in delivery and decay more precisely yet does this without ever wanting to sound like someone putting their nails down the blackboard due to the silky liquid smoothness of the treble tuning.
Instead the gently smooth sweet sounding treble notes blend in with the mids and bass on an even kilter making listening sessions a pleasant experience with still been able to enjoy the intensity of those higher frequencies when they happen yet because the LSX has room for instruments to breath you just naturally hear those treble notes shine through the overall mix of the mids instead of you having to concentrate on finding those notes making it more naturally relaxing sounding and not that tuned type of flagship IEM that is trying to scream look at me I am your analytical high detailed thinned out treble that wants to use razor blades in your ears to make it’s point.
Mids; (4 x BA drivers)
The Lark's mids are definitely the engine house of these LSX with its four drivers syncing very well with a vast amount of detail with a full bodied rich dynamic versatile mids which you would think is a given for a flagship IEM that has four drivers delivering the core information yet it does it with a flexibility and subtlety and clarity you hear the fine timbres of instruments are projected with clarity and deft vibrancy and energy to each note attack.
Coupled with a good noise floor on the LSX which these very efficient IEMs never showed any hiss with the equipment I tried it with is what helps it give it still enough room to breathe in the space it has to work in and keep good clarity with a soundstage that is maybe not the largest I have heard on an IEM but it is still competent enough at this level as I think due to the LSX getting the balance so right in many other areas this never becomes a factor unless of course you are a diehard Sennheiser HD800 fan who craves that dizzying vast soundstage to show of the imaging in an IEM also.
The LSX’s characteristic is actually a fairly intimate closer feeling sound which makes you feel very close to the band performing so much so it feels like at times you are in there with them pretty much instead of the performance in front of you.
Some may prefer it as if you was sitting further back in an auditorium feel or the soundstage was huge but I personally love this type of delivery in the mid-section and although it is an intimate feel the LSX still somehow manages to feel spacious enough to have room around the notes to breath due to the way the depth and headroom Is dialled in on the LSX.
The Lark IEMS even though as mentioned above with the close intimate sound has a very accomplished imaging which is accurately pin point and fast which was one of the straits of this IEM that impressed me a lot which also helps with this IEM feel like they still have a good sense of air between each note due to the accuracy in timing with the imaging.
Timbre is one of the corner stones that makes this IEM shine with the ability to do subtle micro detail with trailing edges on Violins or acoustic guitars you could hear those small changes in the string vibrations of the note decaying with ease due to both that closeness to the music I mentioned earlier.
The perfect timing with the start- stopping of notes making string frets really resonate with the note changes with any type of guitar on the LSX with help of the super tweeter kick in with its liquidity on the higher string notes which making these LSX so non fatiguing to listen to.
Vocals have good tonality, clarity and placement in the soundstage with the low floor noise the vocals stand out without ever been overbearing or shouty.
I would normally point out which vocals in particular an IEM shines with and doesn’t yet any vocalist sounds full bodied and powerful without spiking or booming whilst been able to showcase the versatility of been supple finer details with delicate vocals to the aggressive upper mid-range & treble edge of grainy rock vocals styles just adds to the fluidity of the mid-range naturalness in tonality coming through.
Like the overall soundstage vocals feels fairly intimate and I must admit I am one who prefers the feeling like I am front row with Tori Amos, Stevie Nicks, Gregory Porter, Adrea Bocelli…list goes on, yet given the cosiness with vocals on the Lark’s they always seem to have plenty of separation and headroom to work in and breath on their own in the mids as these IEMs just make you want to listen for another hour at a time with the LSX portraying the accurate vocal qualities tonally makes them very rewarding in this section.
Drums had the same ability as strings do with tonality to trans-fixate on the LSX with the rendering of each bass note impact been played as what it manages to pull off in the mid bass section here is how well the low mids are seamlessly in sync with the upper and sub bass section that there is no disconnect allowing for a more natural decay of instruments so with drums there is no hump or in the lower or higher mid bass frequencies here which I have known to ruin a good overall IEM that I owned in the past.
Considering the lush, smooth and warmer side of the LSX the piano also manages not to be coloured at all in tonality allowing most genres of music to stand out when a real piano is used with the good air and sparkle towards the top end of the key notes with flat notes having good resonance with subtle harmonic decay of strings depicting whether a key is been stroked softly comes through clearly or if a key is hit hard delivers good impact to the mid bass.
Sharp notes loudness rise to great effect in the upper mids helping tracks like fast blues piano playing come to life with good zest and dynamics.
Because of the impeccable timing and depth that the Larks possess it makes hearing the resonance and vibration in notes have feel as well as sound even on BA drivers it all adds to piano sounds having a soul on the LSX and not just a hard sounding dull note played each time.
The LSX is far from not trying to be the most analytical Flagship IEM on the planet and does not try anything other than a midrange that has a good focus on a smooth liquid detailed harmonics with mid bass notes allows for a natural layering of continuous decay of the note through to the lower bass floor.
Even though this IEM has a moderate staggered V shape the mids work flawlessly with the sub bass region does help a lot towards making this IEM have that feel of having a consistent balance in the bass response but also over-all balance to spectrum when you are listening to them as even though the LSX is not tuned flat/ neutral it has just the right balance of tonality, timbre and timing to make these sound organic analogue heaven to listen to with most genres I tried (Classical, Rock ,Dance, Pop, Metal, Jazz, Blues, acoustic, live recordings) making this quite a flexible sounding IEM.
It’s hard for me not to say the mids really are the jewel in the crown that shines on these Larks, not that this makes them any more dominant in any way to the lows or high area qualities this IEM possesses, just the mids are very accomplished because they are so harmonious with the lows and highs is what gives the LSX such a natural balanced feel to the signature when listening to them.
Bass (3 x BA drivers)
Bass will always be a decisive factor in choosing an IEM just in terms of the quantity of bass we each personally prefer from a light weight sub bass or a heavy sub bass on the bottom end and there will always be those that want a more studio monitor neutral flat response or those who want Rob D’s Clubbed to Death bass hit you as hard as been surrounded by 400 watt speakers in a night club.
Yet with the three drivers on bass duties the LSX provides a smooth bass transition through the range with a good tight powerfully weighted kick in the lower mid bass which decays well through the lower frequency range with good control and depth without ever losing control. The LSX may not be the tightest ever bass around out there but it has enough grip and control that a bass hit never sounding bloated or soft with any songs I heard.
The LSX is on the right side of a rich deep dynamic bass without been over rich which I think hits the right balance of having enough bass which would reflect how low you would realistically hear a drum kick go in a live environment for example without been over accentuated falsely. This falls between both true bass heads or neutral flat bass response perfectionists and those who like a bit of added bass that won’t over running & ruining rest of the sound spectrum.
The devil is in the detail as well as the quantity of the bass and from the mids to the lows in a bass note is helped by the clear transients which help differentiate the types of bass notes been played. The lowest bass notes attack and impact it gives feels upfront with the rest of the music yet the reverb and decay of the bass note falling away into that black background can still be visceral in feel below 60hz which is always welcome in a BA driver layering it more behind upper bass note impacts giving the bass a healthy field of depth from the mid to low bass region which is great for rock, blues or jazz music especially.
Somehow it seems Lark Studios have paid as much attention as everything else on this IEM to getting just the right balance for it to blend in to the mix without been overbearing into the mids and stops before becoming too heavy or over bloated with songs.
In all a very good high quality tuned bass that suits any genre well due to its well-controlled tuning and smooth consistent manner that can still have good impact in the right places to give it slam when needed yet maintain subtleness when needed with the detail rendering through the fine timbre showcased on these Lark IEM’s.
Comparisons with the equipment used;
I found no matter what source or set up I tried during my time with the LSX it shone and performed to a high standard and had good scalability when going from say a DAP to a dedicated Headphone amp, it was more just a question which one did it shine with the most & least?....
With the Sony WM1A Walkman the LSX soundstage was made to feel more spatial whilst the Sony’s now more balanced airy detailed mids since a major update last year really shows off the Lark’s resolving mid-range ability with clarity and the now more linear tighter bass on the Sony gives a synergy that makes them an ideal pairing with the LSX’s.
It was a similar story with the Onkyo DP-S1 just the SX1 sounded a bit more neutral and brighter in the upper mids with a more attacking emphasis on the mid bass to the Sony whilst still sounding balanced as the DP-S1 more direct lively approach mirrored the warmer smooth nature of the Lark’s signature to great effect. Vocals really stood out with an air and height to a singers range like it had no ceiling felt like vocals on the LSX was the focused driving force that carried the Onkyo to have a good transparency and tempo.
A third different sounding dap in the newer A&K AR15 A&Norma which feels like it has gone back to the more old school smoother A&K sound compared to its predecessor the more funky sounding dynamic A&K 70 mrkii yet the LSX is still at home enough with the AR15 with the clarity of the mids on both the AR15 & Larks been able to capture the subtle details and reveals a good openness with the top end having a noticeable sparkle yet a certain amount of the natural smoothness the A&K provides without both been over bearing in warmth or richness.
I found with all three daps I tried the LSX they all paired well despite all been different sounding daps albeit they seem to step up in warmth with the Onkyo been more dynamic/ bright, the Sony been richer with still a moderate amount of warmth since the f/w update in 2018 and the A&K has warmth with smoothness.
If it was the Sony before it had the major fw update taking it from super warm and rich with it's boomier sub bass I highly wonder if it would have been too much together with the LSX’s but with the new fw update been more refined, linear and airy than previously with this and the Onkyo’s sig make for an equally as good yet different pairing with the LSX and the AR15 although sounding enjoyable enough they were just missing the bit of life & dynamics missing with the Sony & Onkyo players brought to the LSX with the right balance to counteract the smooth richness the Lark’s have to bring the best of both worlds together.
With amps/ dacs:
Moving on from daps running the LSX through a Pioneer U-05 Dac headphone amp and a Sennheiser HDVD800 Dac headphone amp showed even though the Larks are a very efficient IEM they scaled up really well with a nice big desktop amp and again like the daps it was very adaptable to both the opposite scales of sound signatures the Pioneer and Senn amp/ dacs operated at.
The LSX loves the extra currents on tap of these desktop amps yet managed to still sound quite on the noise floor on both amps which just helped the LSX feel like it had more depth & headroom to play with than it did on the daps which was nothing to complain about to start with but again was noticeable if for example I added the very underrated high quality Vorzuge Pure portable amp to the daps via line out just goes to show what extra you can still get out of these tiny micro drivers with good high quality amping.
The only down side I could find from a signature source with the LSX if the source bass was a bit softer or warmer with the likes of the Senn amp or a Chord Mojo the LSX would still enjoyable enough to listen with but was evidently noticeable when I then paired with a more tighter linear controlled source like the Pioneer U-05 or Vorzuge Pure amps that add that extra tightness controlled attack and neutrality with more headroom and airiness or brightness that counteracts the Larks more lush approach have that same effect the Onkyo or Sony daps did paired with the LSX.
The Chord Mojo pair’s fine with the LSX but the warmth of and the lushness of bot the Mojo & LSX might be a bit too much for some looking to strike that balance of the LSX smooth lush side but not overdo it. But if I was to pair the Vorzuge Pure with the Mojo the story changes on the cleaner signal and power tightens it all up with added weight and extension giving a less softer fuzzy lush approach to the LSX’s so they shine at just the right balance without sounding too soft and dark.
With the Pioneer U-05 coming from the same stable it is very much same type of signature to the Onkyo DP-S1 DAP but with a bigger better amplifier and running with a XLR balanced really gave the LSX a more expansive projection with and headroom scaled it up another level on the smile-o-meter with the LSX.
The last piece of equipment I had to try the Larks with was the Mojos older and now newer brother in the Hugo2 which before plugging It in I knew how much improved the H2 is to the original Hugo making it more versatile, further controlled and nimble than ever with anything that now gets hooked up with it due to its vastly improved voltage section, yet until you hear it you still do not know how these things will inevitably might pair up.
Despite knowing how good both the H2 and the Lark’s are it was a bit like hitting the jackpot as the analogue wizardry of the Hugo 2 analogue sounding dac and balance between aggressive and passive aggressive it can walk draws out the full tonality, dynamics, depth and detail these Larks have to offer and combines the power of the amp to deliver plenty of body and resolution to every note played (especially noticed with vocals here) yet somehow find even more calm and space for the music to be delivered to the LSX drivers made it an all-round performer to the highest standards with Hugo2 driving the LSX.
On the cable front the only thing left for me to try which would of been nice to compare which was unfortunately not available was the PW audio Saladin cable that Lark offer as an upgrade cable to see how much better the LSX could sound as the supplied universal cable only had a 3.5se plug thus not been able to try it in balanced mode in theory.
Alas I have a pure Silver custom made cable (to my spec) by a good fellow head-fier LEDZEP who only uses good quality silver solder on the connections and makes it to military spec literally and can hot swap balanced connections using mini XLR connectors. Up to now I had enjoyed the LSX with the supplied copper cable enough but the Silver cable takes it to another level of clarity and control of notes whilst also adding a slightly more neutrality to the signature just enough without taking away what is already the magic of the smooth, liquid detailed LSX sound.
I was then able to find out the also added benefits of running this now either balanced 2.5, 4.4 or XLR 4 pin so the LSX running in balanced, especially with the XLR balanced finds that extra bit of space and airiness in the soundstage whilst giving more controlled higher headroom with a desktop rig.
I have found some warmer sigs like the Larks in the past benefit staying with a copper cable ( i.e. Meze 99 classics for example) more than a silver just for the natural pairing for the timbre side of things but putting a pure silver cable on (even running in SE mode) gave it a further improved performance whilst still maintaining what makes the LSX foundations to its signature sound so great.
*Foot note on above sessions with using the supplied tips:
Like some IEMs out there may prefer foam tips sonically (like my Vibro lab Mayas do) I personally found that foam tips are a bit too stifling and muddying to the mids and treble compared to silicone tips which became obvious to me in like the first hour of using them I used with the LSX which came more apparent when using with the more neutral brighter sound of the Onkyo DP-S1 or Pioneer amp showed how much information was been subdued in the upper mids and treble so I ended up using the silicone Spin Fits in the end. (again like general ear fit of IEMS with tips YMMV)
Conclusion:
I’m not sure where to start really as from the word go these were easy to get on with and the natural fluidity and striking the right balance of warm with detail yet keep it still quite airy with space and clarity to breath enough whilst been dynamic delivering a natural timbre & tonal quality all round has made it hard to pick any holes in this IEM for those who appreciate dynamic, rich and smooth force of nature enjoying music which still is resolving due to the high amount of varying levels of detail which I have to say won me over quite quickly with me saying to the LSX’s at the end of my time with them “You had me at hello”!
Only negatives if anything on the sound would be for those ears out there that prefer your signature to be a neutral flat response only or a brighter treble sound or further still like it tuned above the 3db in the sub bass department or you prefer your IEM to have that vast big soundstage then I would say these might not be for you possibly but as one who appreciates and loves the In Ear Prophile 8’s as one of beter neutral IEMs I have heard or owning the bass hungry darker sounding JH16Pros I would say give them a try and they might surprise you how they pull you into the music with minimal effort.
That’s of course if you do not already own maybe a IEM like the gorgeous higher resolution JH Layla’s or Obravo master pieces with mind blowing natural visceral bass I have ever heard from a IEM which comes to mind, both of which are in the £2.5k + £3K + bracket to note.
The Lark LSX to me is simply a beautiful mid centric full sounding tonally organic IEM that strike a good all round balance that when paired with a livelier or brighter or less mirrored image of the LSX gets the best synergy and balance for these IEMS.
I even thought about the price which tugged at me a bit as the price to have customs is no more than the universal which then that initially sounds great from Lark considering they also charge no extra for artwork on either universal or CIEM plates that other CIEM manufacturers do but maybe the universal price could still be a bit lower to start with which I was thinking the latter and still do really as I think maybe $200 lower than the customs would be about right.
After ten glorious days with them and listening to plenty of other flagships out there ranging from £1K to £3K in the last year I would have to say I would actually still pay $1699 for the Universal as all I know is if I had the money at the moment I would of ordered a pair from Lark Studios by now which was only clarified for me by myself when I sent them back and consequently missed them greatly within the first day of not having them to hand.
Only other gripe personally as I am a bit of an overall package/ design & purpose for storage pouch, good as the LSX is on Sonic’s alone and the accessories supplied and packaging is solid enough I feel when you are getting a flagship IEM as both a customer and for the companies sakes from their POV they need a sharper eye in the design department to make them stand out a bit more from the crowd with a more modern and sophisticated presentation. The travel pouch or case needs to be more protective with purpose as also the overall packaging and brand design to reflect their high quality product in this very busy and competitive arena in the IEM business so hope it is maybe something that naturally will evolve and improve over time with the company growing with future success as they release more models.
Despite still not been completely perfect I found it hard to fault the overall sound partly as this happens to be my type of signature anyway so tried to do this without there been any signature bias, if anything I was probably harder on it as I know how I like this type of signature to sound from having my Vibro Lab Mayas at the moment (which after this I have to concede this is definitely another level up to the Mayas in most areas for the record!) but more importantly the LSX regardless of its signature managed to nail every one of the many departments like timing and harmonics in making music sound balanced, dynamic, clear and detailed in a enjoyable manner making the LSX fluidly cohesive and natural to listen to for hours at a time.
I know it feels like Lark is new on the scene to some including myself and is this maybe a case of flavour of the month some might ask as some IEMs can have a touch of that sometimes but all I know if you like what you hear from the LSX with their non-fatiguing sound these will last many moons more than just the latest flavour that passes into insignificant to the next big thing next month.
For me the LSX has the long term addiction to portraying music with detail with soul & emotion combined with deft and uncanny tonal performance could make this a cult legend over time sound wise alone as much as the Noble Kaiser 10 or another great 10 driver IEM by the same great man back in the day which have similar signatures.
To finally sign off I personally would give overall a 4.5 only for the fact I think the presentation/ design & quality with case & pouch could be better for the price as well as the universal price could still be a bit lower but for sound alone these Larks would get a 5 rating only for the fact I could not find much to fault when listening to them despite not been the widest soundstage or the tightest tuned bass out there (still above average though on bass) and that they pair easily with different sounding sources as I simply just could not get enough of listening to them in the ten days I had them.
I hope that going by this Lark Studios go from strength to strength going by this first outing from them so will be interesting to see if they can produce other models regardless of costing less or more than the LSX that they keep to the bar they have set for their house sound and principles in the LSX and produce good balanced liquid detailed IEMS that one can just enjoy the soul of the music rather than analyse with a microscope of concentration.
Good luck in this game for the future Lark studios in making more music loving IEM models…
