The ESP950 doesn't exactly scale well as you know. I didn't get that much more extra bass extension from the T2 compared to the stock amp. I would add that I listened to them for two days straight ~14 hours each day, and at highish volumes (92-95db) for a few hours at a time, and that I thoroughly enjoyed them.

I didn't think there was significantly more resolution from the stock amp, but it was certainly better controlled and had better blackground.

Thanks, yeah I thought I'd just ask in case the T2 had the "magic" 

Did you get a good seal?  I'm surprised the bass rolls off so much on these.

I wonder how much lower bass maters.  It would be interesting to do an mp3 test like Purrin's hearing test but rolling off lower bass at different places.

I don't wonder at all.  There's a ton of information under 100hz especially for a lot of my music.  You're starting to sound like a candidate for an unmodded HD800 driven by a DACPort.
