Well, whatever the cause, I just spent some time to verify how great the 009's sound is (w/my Rhino Ray Charles CD and) and the bass is the kind of bass that makes me forget about speakers,
really resonant, solid, and transparent. Again, this is with my 007t/ii amp.
I like to contrast the bass with my LCD3s (w/ a Pinnacle), and the bass presentations are 2 different animals, with the LCD3 a more earth-shaking bass that seems to be more spacious but still
detailed and musical, whereas the Stax 009 bass is quicker and more clearly attached to the musical component generating it, so it's more localized, and it's also more defined.
Both are great, and I love to hear both versions with the same music.
(My Stealth interconnects also help out the bass a lot. I did some A/B testing of ICs and the Stealths really stand out in the solidity and sheer beauty of the bass, along with the sweetest, pristine upper highs. I did these tests with speakers a few years back and settled on the Stealths for good. Kubala Sosnas were a close runner up.)
I just do not hear the 009/007t bass as wooly, and I know what that means from my former Grado PS1000s and JVC DX1000s (and also somewhat from my Senn 600s).
The 009s may have a touch, just a fleeting touch of glare on a strong central vocal compared to dynamics (TH900s, LCD3s), but it always seems to disappear somehow after
about 10 minutes of playing (all Staxes I ever owned -- Omega 1s and Lambdas -- seemed to benefit from playing a while at each session).
And with the Stax 009s, like no other, the sound just seems to dig deep and make the world go away, a trance-like experience. I don't know what it is about these 009s for me,
but they do the music-as-drug thing like no other phones I have owned (and there have been many over the years).
(And since this is with the 007t/ii amp, that is why I endorse it so highly.)
