I still think those who are trying to find an affordable amp for the 009 would like the 007t2 amp.
The bass has a very fine control and transparency and detail, and is clearly deeper than the HD800 bass.
In fact, in contrast to other comments here, the bass stands out as one of the best features of the 009/007t2 combo.
The issue with this combo is that, in comparison with, say, LCD3s or TH900s, there is extreme clarity in the highs,
and it is not as relaxing up there as the non-stats, but it is completely un-distorted.
The 009 has less bass, but it is ample, and the bass is the opposite of bulbous, in fact I have never heard such a beautiful quality bass on any phone or speakers ever,
with NO overhang or annoying softness, which really bothers me (like in JVC 1000s or Grado PS1000s or Denon D7000s).
This combo has brilliant, see-through fast bass.
I like all of these phones a lot and they all get head-time (the HD800s less so, not in the same league as the Fostex, Audeze, or Stax for me).
