    @cocolinho Many thanks, I look forward to comparing these to the other Staxen. Depending on how they measure, I may have to quickly snag a pair.

    my pleasure.
    To be honnest I did not like them so much.
    I had the chance couple of years ago to listen SR007 MK2 on a tube amp (727 II I remember well) and I enjoyed immensely the moment.
    Few months ago I had the opportunity to buy for a very cheap price an old combo SR202/SRM212 which I also liked a lot , I believe it crushes many combo amp/headphones available under 1K. (I owned a big chunck of headphones under 1K available)
    So when I red the reviews about L700 being in middle ground between Omega & Lambda with some 009 techs I took the plunge & bought SR L700 blindly.
    But I think my SRM1/MK2 don't make them justice or I simply expected something different; they are probably very good but my own experience did not reach the level expected.

    Only two days with BHSE, and I have to say it really opens up the listening experience : details, clarity, impact, bass,...
    But SR007 are not the only ones to benefit from it : I wouldn't have thought there was so much potential in my normal bias phones :eek:

    You may have one of the very few units with a normal bias jack. I believe even female HE90 jacks are far more common.

    AFAIK the bias voltage can be changed out of the PSU, so I might look at getting the bias changed on the second jack of my own unit at some point...

    I have to admit I'm pretty spoiled by the BHSE as well. Have you played around with the tubes yet?

    I've hesitated about the NB jack, but as you can see, I've three of them I like two of them a lot (SR-5 and Lambda NB), so...

    A raw picture of it for those allergic to head-fi :

    [​IMG]

    There are some minor flaws that show hand-made stuff (irregularities on the black coating mainly) and bothered me initially, matter of expectations vs reality...and OCD can be strong with me ! But all around, it's a really gorgeous piece of gear.

    About tubes, just inserted the Shugang treasures that come with it (I took the option, mainly for aesthetics reasons :D), and enjoying. I don't want to spend kilobucks in NOS (without any idea of their real lifetime) rarities. The Attorney on HF said Mesa-Boogie EL34 blu grade are the best for current production tubes, and two pairs are easily available for 140 €, I'll try that one day. As I said earlier on this thread, I'm a bit lazy, and not as analytical as Sorrodje for instance ;)

    I'm quite meticulous about gear condition as well, and would have been far too irritated by the scratch on one of the tube rings. Would be a good gesture if you could get that ring itself refinished or exchanged.

    AFAIK the kilobuck NOS tubes are those Philips metal base EL34s that run ~$2k+ for a quad. I'd rather stop at some NOS Mullard XF2/XF4s for $350-600 from the right channels, but this is more for practicality and longevity than any fuss about the tube's sonic characteristics in particular.

    Be careful with Distorsion measurements. Not perfect condtions and probably limited measurements rig explain all oddities.

    Yup. Surprising bass Roll-off . Dunno why. Take it with a grain of salt. I can hear it when I listen to a Sweep tone But i'm still cautious and I'd prefer to see other measurements... Actually it measures like if i had a bad seal. And i can warrant the seal between the pad and the coupler is as perfect as other Stax measurements in this thread. Leaky enclosure by design ? no port I can see at least. This SR-L700 does not fart.. that should mean something about the imperfect seal. I highly suspect it's purposedly designed with a broken seal to improve bass quantity and that explains the slight impression of low-fi bass. Maybe I'm wrong or crazy.

    Distorsion seems a bit high in the low end as well but I'm cautious about my own distorsion measurements.

    I'll publish more pics and thoughts in the dedicated thread

    Subjective impressions :

    Didn't listen to that one. Maybe @3X0 will be happy to give his impressions. It Seems what we measured is somewhat in line with what he hears. :)

    To me, subjectively, the SR-009 is more of a true Omega successor than the SR-007 is. The Omegas have exceptional midrange---maybe my favorite of The Big Three---but the top end is a little fatiguing for me unless I'm pairing it with one of the more easy going Stax amps. Exceptional clarity, tight bass.

    By big three do you mean Omega/007/009 or Omega/HE90/R10? :p In all earnesty I'm not a huge fan of the 007 or 009.

    @sorrodje's superimposition of the 009 vs. Omega is exactly how I hear them -- most robust, visceral and complete bass out of any electrostatic I've heard, significantly more airy and open-sounding (even though 009 is no slouch), and more natural sounding overall. Also IME more resolving than the 009 or HE90 by a hair, though the latter makes an interesting bedfellow.

    Easily my favorite headphones by a long shot -- to the point I'm considering collecting backup pairs.:confused:

    I mean the Big Three of the Staxen: Omega / 007 / 009.

    The SR-007mk1 is my favorite of the group, because I personally find the Omega and especially the 009 a bit too bright for extended listening unless you pair them with warmer upstream gear. A lot of folks feel the 007 is too dark, but that suits me just fine for extended listening.

    I do prefer the Omega to the 009 hands down. That's why I've got two pairs and no SR-009. :p

    From what I heard at your place and a few days later when Milos let me borrow his DIY clone, you should take a seat in the waiting list of people who want to hear it :p

    Just for the record, I did some work on my SR-303 ...

    This is how the SR-303 measures on my rig:
    303_stock.png

    Tried some modifications:
    First: Stripped HD800 pads from any plastic and replaced the Stax pads with them -- see magenta plot
    stock_vs_800pads.png

    Second: Removed disintegrated foam behind the driver. Replaced it with some very thin felt and supported the dust-protection membrane behind the driver with a 2mm felt disk: see yellow plot
    stock_vs_800pads_vsfullmods.png

    This baby sounds very smooth and mellow now.

    Did someone measured the L300? Also with L500 and L700 earpads for comparison VS stock measurements.

    I'm really interested on buying one from Ebay (Japan imported, saves me almost 100€ with the included taxes and shipping), but there are no measurements and practically everyone complains about the stock earpads, would like to know if L500/L700 earpads degrade/improve sound quality apart from comfort.
