I've narrowed my decision to one of these two amps. As I stated in an earlier post I am mostly interested in which one can deliver the best bass for movies, DVDs (action/adventure).

I appreciate the advice/education and look forward to your comments.

i have both amps. there is not much you can do to the ha-2. you can boost or lean the bass on the ppx3-6sn7 to match your cans by substituting tubes.
