Socal Canjam 2023 Impressions
This is my 3rd Canjam. My impressions are getting longer and longer every year as I got more diligent at taking notes (but whether those are high quality is questionable). Bear with me.First I want to mention my reference point. I use Susvara on a non-traditional chain: Holo Audio May, Primuluna Evo 400 pre-amp, fed into 2 AHB2s in bridged mono mode. I started with using just WA33, to using WA33 as a pre into a single AHB2 (a huge improvement), and then to my current chain (even more refinement and details). I came to the show for any crazy stuff to wow me, especially on a pair of Susvara, or anything that’s just different and special. Being used to Susvara on mono blocks, most things will sound a little warmer, a little less detailed, with a bit smaller soundstage, but it’s still a ton of fun to explore, and maybe I will find some black magic. Being at the show floor with my dumb ears, many of my impressions are some variation of “sounds pretty good, but nothing catches me”, though I try to be a bit more helpful than that.
Highlights
Even though they all sound spectacular, this is not a ranking, just a list of experiences I enjoyed a lot.HE-1: It’s just a special experience. It sounds natural and beautiful. I have heard stronger technicalities in almost every aspects, but HE-1 is just so balanced and relaxing. The fact that I’m experiencing this legendary system also adds a lot to the fun of it.
Tungsten with Riviera AIC-10 and Viva Egoista 845: in my book, the only other non-estats headphone that can compete with a well driven Susvara’s technicalities with similar tuning. Hearing this on Riviera AIC-10 and Viva Egoista 845 and comparing with Susvara is through and through awesome.
SR-X9000: I got a chance to really sit down and enjoy X9000 on a few strong but different amps. Gave me a new sense of appreciation for estats headphone!
Amber Pearl: black magic IEM. Warm, rich, full, lush. I normally enjoy a brighter sound signature but this black magic just got me trapped on the dark side. The entire IEM auditioning was a ton of fun for me. I knew nothing and they are all new experiences.
Amps
Viva Egoista 845, Susvara & Tungsten (single sided driver and double sided driver)
Tunsgten is interesting. I heard those headphones on Viva 845 on the first day, and thought Tungsten was much better than Susvara. But on the second day, they don’t sound quite as different as I remembered.First of all, Viva 845 is formidable. Its power reached at least the level of feeding WA33 into AHB2 for Susvara. Only other amp I heard at the show that’s comparable was AIC-10. You can hear from the body, the bass quality, the separation, and the soundstage. Those things are hard to do right on Susvara but they tend to be very noticeable when done right.
On the first day, I spent like half an hour A/B testing Susvara with Tungsten (double magnets) and decided Tungsten had more body, more noticeable details, wider soundstage, and better separation. Going from Tungsten to Susvara, the sounds becomes way softer and muddy. I couldn’t believe it. No other headphones make Susvara sound that way - it’s usually the opposite. I decided Tungsten is a winner.
On the second day, I after my AIC-10 experience (which I will mention later), I compared those again on Viva 845. The difference felt a lot smaller and there’s no longer a clear winner. Susvara opened up more today (I’m not sure why). My new impression is that Susvara has stronger midrange, and Tungsten’s details are still better defined.
I also compared Tungsten’s double sided driver vs single sided. I have to say double sided driver sounds much better. It has a ton more details and body, whereas the single sided version is flat, muddy, and has a weird “grainy” texture to it, like a layer of coarse sand. I even felt the single sided driver one may be defective.
Riviera AIC-10, Susvara & Tungsten (double sided driver).
Just a lot of power. Together with Viva 845, those two are the most powerful amps I have heard at the show that drive Susvara at or close to the level of ahb2 power amp. That power is felt in the richness and the body of the first second of music. It’s not a subtle improvement - it’s something you immediately notice. I got a chance to A/B Tungsten and Susvara on AIC-10. Both of them are on the neutral/slightly bright side. Imaging is on par. Tungsten has more energy and decisiveness. Susvara felt softer overall, but has stronger mids, more air between instruments and a slightly bigger soundstage. Special thanks to @goldwerger for recommending and bringing me to the booth and lending me his Tungsten for auditioning.MASS-Kobo Model 465
Many people had very good things to say about this amp but I didn’t quite catch the magic. Yes, it is a powerful amp but I don’t think it is quite as powerful as AIC-10 or Viva 845. I get pretty decent soundstage, detail and slam on Susvara, but it lacks a certain “magic” in those departments that the other amps had that got me like “yes, this is it”. I do think it is more powerful than Envy and Bliss.Zähl HM1
After seeing Golden Sound’s highly positive review, I wanted to try this amp at last Canjam but it had a lot of noise in the signal. This year, HM1 seemed quite popular as there’s ALWAYS someone there. Now onto the sound:It is a powerful amp - I want to say maybe it’s little more powerful than Envy, but less than AIC-10 or Viva 845. The most interesting thing about it are the crossfeed knobs that change the soundstage and sound direction. It can move the “main” sound (like a singer’s voice) from slightly left to the middle to slightly right. And it sounds just as good in any position. The knobs can adjust bass and treble. They work like EQ but it’s easier and maybe sound a little better. I want to note they don’t change the quality of the treble or bass. E.g. It won’t make bass go deeper or become more tactile, but it will give more quantity of it. As for the soundstage adjustment, the knobs can expand or shrink the soundstage, but the widest it can go is not super wide. What I found interesting is HM1 achieves all these adjustments without adding artifacts or color to the music. It’s very nice.
YAMAHA HA-L7A
I tried this amp with the YH-5000SE. I mainly wanted to see the “field change” knob that gives you different sound presentations.What I found is it meaningfully changes the soundstage but it doesn’t do it the same way as HM1. They give you a few presets to render music. The “outdoor live” setting makes vocal tracks sound like coming from huge speakers in a park, and “concert hall” make them sound like in a concert hall with a little echo effect. Those are pretty fun to play with, even though you can’t fine tune the aspects like HM1. I also don’t think you can use HM1 to achieve the same effects that HA-L7A gives you. But one grip I have is those settings change the sound quality - they don’t sound quite as natural as the original and I feel some details are lost. In that regard, I feel the changes you can make on HM1 are more desirable because they don’t have those side effects.
Bartok with DCS Lina clock and amp
I really appreciated the way DCS sets up their room. Everyone gets its own corner which helps reduce ambient noise.This stack sounds very good. But my untrained ears can’t pick out anything outstanding. With Susvara, they reminds me of WA33 without any power amp. Similar level of details. Similar soundstage. Similar energy and bass. Does not give oomph to Susvara that you get from power amps. I feel Susvara may not be doing this stack justice simply due to the lack of power. With easier to drive headphones, maybe this stack will really shine.
Feliks Audio Envy
I want to thank the ZMF room for having an excellent range of amps to try. They even had the Western Electric 300Bs on the Envy unit there.Envy definitely gives more juice to Susvara than DCS stack. Lots of energy and decisiveness. It sounded really good but didn’t get to the “magic” level of Susvara performance for me. The body, bass, or soundstage didn’t quite reach the level that WA33 + AHB2 had, but very enjoyable nevertheless.
Holo Audio Bliss
I didn’t spend a lot of time on Bliss because I tried it right after Envy and decided there’s not a ton of meaningful, non-subtle differences to quickly point out. I think Susvara on Bliss is quite enjoyable; it has a little more details than Envy but a little less slam.Ampsandsound Red October
I always swing by for a listen when seeing Red October at a show. I know it’s an extremely high performing gear and always enjoyed hearing it. It has a ton of power and very big soundstage. Super good details. Very dynamic. I think it has a power similar to Masskobo 465, and probably more power than Envy and Bliss. But it’s not often talked about. I think more people should hear this amp!Boulder 812
I got a chance to try Boulder 812 with Susvara unfortunately I don’t think it can quite power it. I had to turn the volume knob to the maximum for normal listening level and there’s lots of audible clipping at that point so I can’t spend too long with it. It could be some settings are wrong or the chain is not set up for high power.LTAZ10e
I only listened to Caldera on this amp - maybe I was too lazy to pull out Susvara from my backpack. On Caldera, this amp has a very wide soundstage, and excellent separation.Double Heli Chimera Cable
Think this is worth a mention. Thanks to Chris at Mimic audio, I got quite a bit of time to carefully A/B this massive top of the line cable with my Norne pure copper cable. The difference is not subtle - immediately the sound feels “bigger”, the presentation becomes sharper, like wiping clean a fogged window. The bass becomes stronger and its quality becomes better - meaning the bass goes deeper and its shape is more defined now. Going back to my cable Susvara sounded a tad muddier and softer.Headphones
HE-1
A dream come true to finally demo the legend! I really liked that Sennheiser has a private, quiet room for it. I think many of HE-1’s best qualities can’t be properly appreciated on the noisy main show room. Now onto the sound..Somehow I expected HE-1 to have a very warmish, silky smooth tuning, but it’s not like that. HE-1 has a ton of details, about the same as Susvara, but has a smaller soundstage. From treble to bass, everything is extremely well balanced. There’s no one single thing that catches my attention. It is a very airy presentation, but at the same time, bass is dynamic and very engaging, but not a lot of slam (it won’t move air like Abyss). Mids have good energy and details. Treble is detailed and has good texture but it’s not harsh. Nothing is exceptional, but everything is just very good, and there’s no fault. HE-1 sounded like a supercharged HD600. It’s flatter than HD650, and more engaging than HD800. It doesn’t have a lot of body to the sound like a well driven Susvara or Utopia. It also doesn’t have crazy realistic imaging like the king of imaging (IMO), the Aperio, or very wide soundstage like Susvara on steroids. HE-1’s sound feels like coming from a normal headphone, but from top to bottom, it’s just so well put together. So, with black magic nowadays there are chains that can do many things far better than HE-1, but HE-1 is just, unsurprising and beautiful, and that has its place.
Also in the HE-1 demo room there is the first ever open headphone that Sennheiser produced in the 1960s. It doesn't sound that bad! Yes there's not a lot of details, but it sounded like an average modern over the ear headphones you can buy for $10.
Austrian Audio - The composer
Pretty good overall. Nothing stood out. It is a little dry. It has a lot of texture. Treble has a little too much energy. Female vocal sounds a little too bright. You can adjust the angle of the driver to get different fit and sounds, which can be interesting, but I didn't try it.T+A Solitaire P on HA-200
Quite warm. The soundstage and imaging is good, but not extraordinary. Has a bit less details than Susvara. Bass is dynamic but nothing crazy.Drop + Grell
I’m not sure what to expect, but the tuning wasn’t to my liking. When it was plugged into the SMSL amp, it was very muddy and there were no details to hear. I chatted with the representative and asked them if this is normal, and they offered to plug the headphones into their Drop + xDuoo TA-84 amp. This is more like it - now there’s actually a soundstage. The drop/grell’s tuning is heavily leaning towards lower frequencies. A lot of bass with a lot of energy but IMO it bleeds into other frequencies, making them sound muddy and veiled. The signature is very warm. The booth had HD6xx (practically the same headphone as HD650) and I had a chance to A/B them. HD650 sounded cleaner, more detailed and balanced. There are probably people who like the Drop/Grell tuning, but I can’t bring myself to enjoy it.YH-5000SE
The booth has two pairs of pads to try! The representatives are very nice and eager to see how you like different pads and will swap them for you.With leather pad: Wide soundstage. A tad warm compared to Susvara. A little on the thin side. Not a lot of body/weight to the sound.
With velvet pad: Quite a bit warmer sound than with leather pad. But less detailed, and overall presentation feels muddy. I liked the leather pad more.
ZMF Caldera
Compared to Susvara on Envy: warmer than Susvara. Slams harder than Susvara. Details stand out quite more. Coming from Caldera, Susvara sounds softer, but more refined. I think Envy is driving Caldera fully but not quite as fully for Susvara. Midrange on Caldera is very recessed compared to Susvara, making Caldera very V shaped. And interesting thing to note is the soundstage on Caldera feels like a dome around my head, and there’s a decidedly a boundary, a limit where sounds can stretch to. Soundstage on Susvara, while not quite bigger, doesn’t feel there’s a boundary. I suspect this is due to Susvara has darker “ambient sound” than Caldera on many tracks. This hides the boundary. In other words, Susvara has a darker background. Last year I heard Caldera and really liked it, so I spent a bit more time with it this year, but I don’t quite like the recessed mids.ZMF Atrium Open
Didn’t spend a lot of time with this one, but oh it’s so pretty so I had to give it a go. The mids are a lot more prominent on Atrium Open than Caldera. Way less details than Susvara.HEDDphone 2
I heard Heddphone one previously and felt it sounded too soft and muddy. The Heddphone 2 sounded much better compared their predecessor according to memory. It’s warm, but it’s clean. I felt it sounds even cleaner than Caldera. Imaging is good, and music has good body to it. Female vocal is beautiful - reminded me of HD650. Soundstage is smaller than Susvara. Details are less than Susvara. Slam is stronger than Susvara.D8000 Pro Limited Edition & Kallyste Amethyste
I first heard it on Viva 845 and wanted to A/B with susvara, but didn't get a lot of time. Compared to Susvara, it is warmer, has a little less detail, and it’s a little softer.Worth mentioning, I did get a chance to hear this headphone on the Kallyste Amethyste, just on the right side of the HM1 stack, and the gentleman I just met (Sacham?) said “you have to hear this”, and boy it was wonderful. Very full-bodied, super engaging, very 3D. This sound IMO gets the closest to my experience of Susvara on mono blocks. This is 100% of that magic of well driven TOTL headphones. It’s just so right and beautiful.
DMS Omega
It’s a very warm headphone. It has way less details than Susvara - the bass felt muddy and soft. Soundstage is ok. It reminded me of Drop/Grell, which I didn’t care for.STAX SR-X9000 and SR-009S on SRM-T8000
I sort of ran out of items on my wishlist on second day so I just wandered around looking for anything interesting. I went to the room deepest inside where Stax and Woo Audio are, and saw a few empty seats. I never before had an opportunity to demo the best stax headphones side by side. They had two headphones running into the same SRM-T8000 amp - excellent for comparison!Sound is super airy. Very floaty. Very typical estats signature - non-offensive and a ton of details but never get in your face. Bass is a little light, but its shape and texture are excellent. This combo feels similar to HE-1 in that it’s so natural, detailed, airy, and has excellent imaging. It felt a little brighter than HE-1 and I think HE-1 has a secret source in the tuning that made it more engaging than X9000. But still, X9000 in this chain just draws me in and whereas on so many other chains I just tend to focus on their technicalities. This one, while the characteristics don’t seem as impressive, it just relaxes you. I went to certain passages of songs looking to analyze them but kept drifting to just enjoying the music.
I compared X9000 with 009s. The latter is quite warmer. Its soundstage is smaller, and it has a “cave sound” feeling. The bass is stronger. Whenever I switched from 009s to X9000, the music just opened up and the soundstage got bigger and more relaxed. And felt like a breath of relief. I very much liked the X9000 - its tuning is similar to Susvara.
Woo Audio 3ES & SR-X9000
Compared with T8000, 3ES has stronger bass and is a lot warmer. The soundstage is smaller. Music notes stand out a little more with more energy. Treble feels very slightly harsh. Much more sub bass than T8000. I felt 3ES turned X9000 into a 009s, and that signature didn’t have the magic for me.Blue Hawaiian Special Edition & SR-X9000
I haven’t heard BHSE in a year and previously just remembered it sounded very energetic. What’s a better opportunity to demo it with X9000 right after I heard X9000 on T8000 and 3ES?!BHSE is very special and yes I hear it in the first second. The 3D imaging is oohhh so good. Not crazy like Aperio, but the imaging is decidedly better than everything else I heard on the show except maybe Susvara on steroids. BHSE is a little warmer than T8000, but not as warm as 3ES. The sound is very rich and has a lot of body. The bass and sub bass are not exaggerated but very high quality. Definitely more than T8000, and on par with 3ES. I think it combines the best qualities of T8000 and 3ES: the staging and detail of T8000 with the bass and energy of 3ES. Probably because I’m sharing the source with another gentleman so I’m not as relaxed, I didn’t quite get the “draw me in” feeling I felt with T8000. After hearing BHSE, I went back and listened to T8000 again. Yes, the sound is thinner. Yes, the sound is floaty. But the presentation is just musical. I don’t know what it is. Yes it has lot of details and they are not offensive or even stand out that much, but they are just there and draw you in.
IEMs
I am not an IEM guy. I heard a few IEMs in a previous canjam and owned the EE Odin for maybe a year before I sold it. So my ears are way less trained on IEMs. I didn’t know any of the names when I tried them, and even now, I don’t know the price of most them. I will just speak what I felt.Empire Ears Raven
I liked EE Odin, and Raven felt like a good improvement on it, if you like bass. I’m not very into bass but I can appreciate the fun of it, so I like the fun factor. Raven brings the “knocking off socks” bass of EE Legend Evo to the base sound signature of Odin. So that’s a big change. Then, I think the mids are tuned to be more forward. Vocals sound excellent - very smooth but still with a lot of details. Good 3D imaging. The bass can feel a bit too boomy on certain tracks even if you appreciate its massive fun.Then, seeing me trying out the Raven, @wazzupi brought me to the unique melody’s table and started introducing a bunch IEMs that I have not heard of before and asked me to try them on. This wasn’t on my wish list but I figured what’s better than going on an adventure especially when you have an insider guiding you, and at a show like this?! So I spent the next hour plus exploring whatever I got recommended.
AROMA Audio Jewel
Immediately, this feels like a “susvara” to me. Not boomy. Not warm. Very detailed, very refined. Not harsh or etchy. Sound is on the thinner side. It felt like the detail king tastefully done.Unique Melody Amber Pearl
This one gives me a big “wow” factor. Syrupy steroids. It’s a LOT warmer than Jewel (and all the other IEMs I tried), and while it’s usually not a good thing from my experience (see all the examples above), Amber Pearl is a big exception. It’s OMG so rich and full. Lush in the best way possible. The overtones are damn impressive. Listening to guitar on it is an experience. Soundstage and imaging is maybe a little better than other IEMs but when you have such a full sound they add up to what you feel is just a “bigger” sound presentation than others. Bass is very impressive but not over the top like Raven. I tried female vocal on it - beautiful. Very refined. Any reasonably detailed IEMs or headphones will have a little bit of sibilance on my test track, but here, there is none. I think it’s probably the only IEMs I tried that didn’t have sibilance at all on my test track, which just goes to show how warm and smooth the sound is.Oriolus Traillii
Sound signature is quite similar to Jewel. Not warm. Quite detailed. But it has more bass than Jewel. Female voice has a bit more texture than Jewel but also more sterile (could be because I just listened to Amber Pearl). Female vocal has a little sibilance in my test track, which clearly shows it’s on the brighter side of sound signature.Elysian Annihilator
A ton of details. Very textured sound but very dry and etchy. Sounds sterile. Especially with string instruments. Ok bass, nothing to point out. I’m not a fan.Aura IEM by Vision Ears
It’s dry like the Annihilator but it’s less resolving. I didn’t listen to it for very long before giving up.Canpur CP622B
I had a hard time fitting it in my ears; it could just be me. Sound is very clean but doesn’t come off overly detailed that can feel unnatural. Bass is very good too. I felt the overall presentation is slightly better than Jewel and Traillii but I can’t quite put my fingers on it. It’s just overall very balanced and there’s nothing that I can point to.Aroma FEI WAN
3D imaging stood out as the first thing I noticed. Very holographic. Bass is very dynamic. It is a little warmer than Jewel and CP662B but not nearly as warm as Amber. The music notes have body, which contributes to its impressive imaging.Noble Audio Viking Ragnar with stock cable
Sound is very airy. 3D imaging is quite good. Quite warm and thick sound. A little dry compared to the more refined sounds of other IEMs, and has maybe it has a little emphasized upper midrange? But that’s going into a level of detail my untrained ears can’t pick out at the show floor.Viking Ragnar with their Magnus 8 cable.
Hugo recommended I have to try the Viking with their “8 wire” cable. So I did! Immediately, much more details. More resolution. The 3D imaging become quite a bit better! Now it’s apparent Viking Ragnar’s sound signature is on the warmer side, as the notes become more defined in their timber. Dryness is also more apparent now (as resolution brought out the sound texture even more), but it didn’t hinder my overall enjoyment. The air and impressive 3D imaging made me think this super charged Viking Ragnar maybe the second most interesting IEM I heard, after Amber Pearl. I can’t help but wonder what Amber Pearl will sound like on this cable!64 Audio Volur
After my interesting IEM journey on day 1, I started taking notes of IEM names from people’s impressions. Volur become a new wishlist item so I went to check it out on second day.The sound is very airy. Bass is pretty good and dynamic, and not overly done. I believe it has more bass than the other IEMs I heard except Raven, and the bass felt quite clean and satisfying. Volur is on the warm side. Overall, an impressive sound but no “wow” factor for me.
The people
Lastly, I want to just mention how much fun I had with all the awesome people. Echoing many of the others’ experience, I started going to canjam for the gears and the people part always turned out to be even more fun. Thanks to @warrenpchi and @wazzupi for inviting me to the dinners and parties, for introducing me to many fellow enthusiasts. Hearing passionate debate on IEM and headphones differences over the dinner table is just something special. The water cooler folks are a special group. I also want to thank Chris from Mimic audio for always being so patient, friendly and helpful. You folks are awesome. Until next time!P.S. Baekjeong KBBQ was worth the wait!!
