(just kidding)
You've just thrown a monkey wrench in my thought process.
I need to replace my B&K Ref 7270. Been thinking about either the Gemstone Blue Diamond, Outlaw 7700 or the Emotiva MPS-1. All around $2K US for 7 channels.
I could buy seven A500's for that same money and end up 500W per channel.

(I getting wood just thinking about it)
Oh Lord, please save me from Loserwife's wrath!
EDIT: I think mulesteritus is a communicable disease.
