    i'm on a roll... the kgsshv

    In my experience (could be placebo), even correcting the voltage balance and offset, a warmed up 500V KGSSHV will sound better compared to cold. That is to say, a servo wouldn't improve the sound much if the amp is cold. Does that sound about right in your experiences?

    At lower volumes, do balance and offset voltages that are farther away from zero make a bigger difference vs higher volumes? For example, my 500v kgsshv is usually ~2v away from 0 for balance and offset. If the left channel is negative 2v and right channel is positive 2v, would that be audible at low volume and not higher volumes, or is it always 4v/500v difference at any volume, which is less than 1% between the channels?

    It'd be great if someone with a 007mk1 can compare the subbass quantity vs the 009S with dance music. I can't live without the 007mk1's bass

    This has been addressed before, but for the YOLO types, if you take off the black cloth debris cover on your 007, the clarity improves by 10-15%, which is very significant. Do it at your own risk though. I love my kgsshv + 007mk1 so much. I can't thank Stax and KG and spritzer and the community enough. My system has become my most cherished possession by far. It's been a long journey where I didn't believe perfection existed, until now

    In my experience, channel imbalance has been a problem predominantly with the Omega type drivers. Stax and channel imbalance seem to go hand in hand unfortunately.

    It's quite a shame, considering the Stax high end sound is basically "perfect" and "worth it" if you take care of the equipment to last 10-20 years. You can spend ~$6k on a system that provides 15 years of enjoyment, granted no technical issues appear with the headphones heh I guess headphones will always be niche because it messes up your hair

    I was surprised when I saw Stax's sales numbers, assuming they are true. $1.3 million a year is only 325 SR-009.

    My 007mk1 has the most "meaty" sound of all the stats I've tried, on par with the HE-1. I hope the new 009S is similar. The only thing keeping my 007 from "perfection" to me is the excursion distortion. I've had the 007a (made in ~2015 I believe), and the bass was nothing compared to my 007mk1 in terms of headphone rumbling character. It also had too much sibilance.

    I'm thankful that Stax was able to engineer the perfect headphone sound for me. I'd like to support them by buying the 009S, but I'm basically 100% satisfied with my 007mk1, and they're now owned by Edifier anyway

    Basically gold drivers and MLER"2" instead of MLER I guess we can't complain since they're the same release price.

    In the example song I posted, it's actually not very "loud" volume wise, but it's definitely a lot of bass. My issue isn't that I listen to everything very loud, but sometimes I hear distortion, and I have doubt in my mind whether or not it's my system or the music, and that leads to decreased enjoyment. I just want to point out that I think the 007mk1 on the kgsshv is magical. I've heard almost all of the best headphones (ironically not the 009), and I've yet to find one that bests the 007mk1, especially in it's subwoofer-like subbass. It's also incredibly non-fatiguing and neutral. Yes, it's missing a bit of high end sparkle, but I don't find myself wanting more.

    Yea, with my Lambda Nova Signature, when there's too much bass, it starts to either rattle or sound flappy / flabby. My 007mk1 doesn't sound like that, but they have a totally different enclosure, so maybe the symptom presents itself differently.

    Thanks for trying it out. "To the bone" doesn't pose any problems for my 007. "Gave your love away" has a lot more bass, to the point I feel that my 007's drivers can't handle it.

    I've tried it with several different DACs and input types. I find it very odd that not more people have encountered this issue. I think the active Stax community isn't very large and perhaps not many listen loud (~70% of live volume). With the YouTube video I posted, the distortion occurs within the first 10 seconds, and without the distortion, the bass sounds very smooth. When it's distorted, it has a bit of grain and bassy crackles, just like when a dynamic speaker can't handle the bass. The song is really smooth, so you can definitely listen to it loud.

    I'm using the 4vrms XLR output from a CEC DA53 balanced DAC from 2007. I find that the distortion is volume dependent. For example, at around 12pm with the XLR output, I can hear the distortion, and with the 2vrms RCA output from a different DAC, I can also hear the distortion at around 3pm (similar volume as XLR at 12pm). I've tested all sorts of variations over the past month (optical, USB, different amps, different sets of Stax, different cables, etc.). The only thing that I haven't tried is a different power/outlet environment.
