  • The first SR-Lambda series was introduced 36 years ago and it has further developed into a new-generation SR-Lambda with its newly designed enclosure - the new SR-L700 advanced-Lambda series Earspeaker.

    TOP QUALITY SOUND ELEMENT
    The SR-009 hand selected thin-film diaphragm as well as fixed electrodes machined through three-layer stainless etching using heat diffusion has been employed for the SR-L700 sound element. Thus, rich deep bass response, delicate high frequency and soothing mid-range has been achieved in a balanced sound.

    10-CLICK TYPE HEADBAND ASSEMBLY
    The headband (ARC) assembly of the SR-L700 is equipped with 10-click slider mechanism for head pad height adjustment adopted from SR-009. Once adjusted, the slider always maintains its optimal position to make readjustment unnecessary. This enables you to enjoy hours of pleasant music listening with utmost comfort.

    LOW CAPACITANCE WIDE HYBRID CABLE
    6NCu high purity 99.99999% copper wires are employed for the core wires, and six silver plated high purity 99.9999% copper wires are arranged for the perimeter. The whole cable uses the conventional wide format parallel structure to lower the capacitance between each wires and finished with the most suitable structure to drive the earspeaker.

    NEW GENUINE LAMB LEATHER EARPADS:
    New earpad design is carefully hand crafted with genuine lamb leather for utmost comfort for hours of music enjoyment as well as sound performance.

    The Holy Grail

    Pros - Perfect treble, spot on vocals, impeccable mids.
    Cons - Plastic build and electrostat bass
    I have never owned a pair of STAX or any electrostatic headphones or iems prior. I had the opportunity to hear the best available at Can Jam LA 2017. After hearing the MrSpeakers Electrostat, Sennheiser Orpheus, Sonoma, and STAX sr-009, sr-007, L-700, L-500, L-300 on the Headamp Blue Hawaii Special Edition. I was set on buying a pair of L-700's, which I am wearing right now! I am using a Headamp Koss DX Edition electrostatic amplifier.

    I have owned and had a chance to listen to numerous dynamic driver and planar magnetic headphones, such as the Focal Utopia/ Elear, Hifiman Susvara, Hek/v2, Abyss 1266/ phi, HD800/s, Sony z1r, Pioneer SE-M1, and Audeze LCD-4.

    With that being said, the only thing that the L-700 loses on is the lack of bass response compared to planar magnetic and dynamic driver headphones. In every other aspect, the Stax L-700 beats every pair of headphones in tonality and musicality.

    I personally Used EQ to improve the bass response to make up for the lack of bass. I also attached Mrspeakers Electrostat pads onto the stock brackets with bass ports unblocked. The size of the pads are identical to the Sennheiser Orpheus dimensions.

    I listen to every genre you can imagine, the only sonic imperfection is the lack of bass that is improved with EQ and the Mrspeakers ear pads. The soundstage also increases with the electrostat earpads too. Having heard the Sr-009/007 side-by-side, I would still take the L-700 over them due to their price vs performance bargain. They beat out the sr- 007 and aren't far off from the famed sr-009. I personally sold my other headphones and am completely satisfied with the L-700!

    Musical and Easily Enjoyable Stax
    Written by Kiats
    Published Feb 22, 2016
    5.0/5,
    Pros - Excellent tonality; musical; easily enjoyable sonic signature; easy to match with amps
    Cons - May be fragile because of plastic parts
    I am a relative newcomer to Stax and electrostatics. I would say that my journey began in or about April 2015 when Gavin, aka Spkrs01, was kind enough to introduce me to this wonderful part of the music world. Spkrs01 was absolutely wonderful in that he was unfailingly patient and kind with my endless stream of questions. Anakchan has also patiently offered reliable and honest views.
     
    I started off with the SR-009 and SR-007 Mk1. Thereafter I picked up a pair of SR-007 Mk2 late last year to complete the line-up of Stax Omegas. Aside from my Stax set-up, I also have a little collection of other full sized cans: most of the top tier Grados, the LCD 2 & 3, HD700 & 800, Hifiman HE-6, HE-5LE, HE-560, HE-500, HE-1000, Fostex TH900, AKG K702 & K812, and  the Final Sonorous X and the Abyss.
     
    I still remember when Spkrs01 and Anakchan were at the May Avic Fujiya Show, they had both heard the new Stax Lambdas which were being unveiled at the show. Both of them gave glowing impressions of the L500 and L700. The common thread was they liked the tonality of the Lambdas. Especially the L700 which was more refined and perhaps may extended in its range.  It was indeed exciting to read the specs and other details about the L700: http://www.stax.co.jp/Pdf/Export/Web_News_SR-L700-E.pdf. I had mentioned the impending release when I had dinner with Anakchan in early April when I was in Tokyo for meetings. I am glad that I did and both Anakchan and Spkrs01 gave it a listen at the show.
     
    I immediately dropped a note to Claire of Jaben Singapore for her to secure me a pair when it became available in Singapore. The exact date escapes me but I recall that the new Lambdas were launched in Singapore in time for the International Sight & Sound Exhibition 2015 which was held at the end of November 2015. When Claire informed me that my set had arrived, I quickly drove down and made a pay, grab and run. The lovely Sheila, who works with Claire, bore witness to my famous whirlwind check out process.
     
     
    Home Desktop Stax Set Up
     
    Currently, the Stax chain comprises an Auralic Aries (with external linear PSU), connected via a Audiquest Diamond USB 3 cable to a Bricasti M1 DAC and then a pair of Tralucent Uber balanced interconnects to the Cavalli Liquid Lightning 2, and then pass through to the VAW 8PS via a pair of Toxic Cables Silver Venom balanced interconnects. Power cord for the DAC and the Liquid Lightning 2 is a Tralucent Uber power cord, while power to the VAW 8PS is supplied by a Tralucent Silver/Gold power cord. Power to the components of the desktop rig and sources is fed through an Isotek Aquarus and all the power cords use US plugs. Mains power is fed to the Isotek Aquarius via a Tralucent Uber power cord.
     
    My Synology DS 414 and a Seagate Backup Plus HDD (connected directly via USB to the Aries) are powered by the new Plixir Elite BDC Power Supply kindly customized for me by James Soh of Sound Affairs in Singapore. James had also helpfully suggested that I run a separate switch for the audio components away from the wifi access point. The switch is also powered by the Plixir Elite BDC Power Supply that James customized for me. The Aries and the Synology DS414 NAS are connected via the dedicated switch by a pair of Ranko Acoustics OCC audio LAN cables.
     
     
    Build Quality
     
    The build quality of the L700 is pretty good for its price point. There is probably more plastic or synthetic material on this Stax can that I have seen prior to this, as compared to the Omegas. However, I am not saying that it is flimsy. It is well made and put together. The nice touch is the genuine lambskin on the ear pads, which is probably the most important part, if you ask me.
     
     
    Comfort and Isolation
     
    Although the ear cups of the L700 is in the classic rectangular shape of all Lambdas I have come across, it was surprisingly comfortable. This is not least because of the lambskin ear pads. The clamping force was also quite light, although still adequately firm.
     
    As for isolation, well, it is as isolated or not as the rest of the Stax cans. It was is really an open can and if isolation is what you are after, this not the can for you.
     
     
    Music Genres
     
    I have a decently comprehensive music collection with a wide repertoire. Early church music, classical music, classic jazz and  extends to modern jazz, rock, pop, acoustic vocals and even some EDM and Indie (thanks to Awry and Destrozer who are happy to educate me).
     
    What I will say about the L700 is that it is such an easy can to match with different genres. It handles them without skipping a beat. It is also pretty forgiving of the less than perfect recordings because of its tonality. It lends itself to pure musical enjoyment.
     
     
    Sound Quality
     
    I think the L700 is fairly well balanced: the trebles are extended, the mids border on lush. The bass, while it is quality bass, is not quite in the same class at the 009 or 007 for the matter. In terms of tonality, I think it sits somewhere between the 009 and the 007. Which suits me perfectly as I was looking for something which would have a place in my current range of Stax cans.
     
    The L700 is very musical and enjoyable. One can just sit back and relax, be absorbed by the music. That is the most charming characteristic of the L700: it is wonderfully enjoyable and even addictive. If you are looking for a Stax can which is relatively easy to drive, thoroughly enjoyable with excellent sound density and depth and yet carries the quickness in response of an electrostatic, this is the Stax for you.
     
    While there have been some exuberant suggestions that the L700 is better than the 007 and a possible candidate for 009 replacement, I think these are perhaps a tad euphoric. Do not get me wrong: I thoroughly enjoy the L700 and think it is an excellent Stax can. However, in terms of soundstage (both width and depth), detail retrieval, nuances and suppleness, the Omegas are still in a class of their own.
     
     
    Pairing
     
    While the L700 is admittedly not as finicky or difficult to pair with amps as the Omegas, it still appears to appreciate the additional driving power of the LL2 and VAW, and is sufficiently transparent to allow the differences in character between the two amps to be apparent.
     
     
    Conclusion
     
    I am glad that two reliable pairs of ears in Spkrs01 and Anakchan got to hear the L700 at the Avic Fujiya Show and that I was able to take the leap of faith as a result. I am as always grateful that Claire was able to secure me a set as soon as it was available in Singapore. The L700, while hardly being the last word in electrostatic technology is a very musical and easily enjoyable pair of Stax can at a very attractive price..
