I listen with my girlfriend a lot, and having an amp with 2 Stax jacks and both a 009 and 009S is freaking awesome. Most ladies don't have the patience or inclination to sit and listen tethered like this, but we both enjoy it a lot. I also have a very high-end 2ch setup that we primarily listen to, but even still sometimes the Stax just hits the spot! Also my T2 has been out of commission for a bit, and also my hev90 balanced, so finally I dusted off my last remaining KGSShv - an older 500V IXYS implementation (on-board heat sinks), that was always my favorite of the KGSShv flavors despite not being as warm as the Sanyo builds. Wow, the KGSShv still rocks! I know it can't stand head to head with a T2, but now that it's been a while it sounds glorious in its own right. The 500V IXYS tonality is closer to what I deem "neutral", and not too far off the T2 in that respect. Its treble isn't subdued by any means, but it holds back that last bit of bite & energy that can make the Carbon too aggressive for a plain 009 (in some systems). Purk offered to loan me his Carbon, and I know it's better overall, but I think I'll be just fine getting reacquainted with this old friend.
