In terms of SQ and power to drive cans such as the HD580/600/650, where would the portable 2007 be?

Would it be worse than the 2007 but better than the 2006 due to the electronics? Or would the lack of power affect it such that the 2006 is better?

Thanks.

Your question was already answered by the man himself at post #8 above:

I'd say the 2006 Desktop Module is slightly better than the 2007 Portable Micro Amp. They're pretty different beasts, the new Micro Portable is an 8397 chip that's biased moderately into class-A. This is a common chip for portable amp makers and we think it's an appropriate solution for the class of amp. Biasing it into class-A may be more than most do, but we've got a pretty big battery in there.
