So, did you have an answer to my question that you'd like to share?? Here's the question:

Anybody have an opinion they'd like to share? I'd love Pass, can barely afford used Bryston, and would like to spend even less than that...
- The Hafler amp that you're looking at.... - kootenay 22:26:59 09/22/10 (1)
  is a good one, as I have the Hafler P500 which is the pro model version of the Hafler 9505 that is configured to mono to which I'm using to drive the center channel.
  
  As far as the sound is concern the Hafler is a poor man's Bryston it has all the quality that Bryston has, except, it lacks the bottom end control.
