New amps for Classe Wilson system
Stick with what you know and love IMO. The JC1s are the one part of my system that I do not consider changing, they are fantastic amps.

Well played Marakanetz! :) 
today i got my new Focal Electra 1038BE ,help
With your budget, and the fact that you are still missing 3.1 of your home theater, I think you are going to run out of budget quickly if you are going to match the Focal BE's.If so you may have no other choice than to go with a receiver or lower ...

Are all external hard drives the same?
I use Hitachi Ultrastar 1Tb drives and have had excellent results with them. I know that many VERY large cloud storage companies (which I won't name but guarantee that you have heard of) use these which speaks volumes to me. 
room size for Pass XA30.5 power amp

Mcintosh 601's vs Classe CA-M600's
The JC-1's are absolutely in the same class as the amps you mention. Don't let their price tag fool you.Yes I am a current JC-1 owner, and have owned amps from Mark Levinson, Classe, Linn, Pass Labs, Ayre, and a few more I can't think of at the mo... 
Classe CA-M600 vs Parasound JC-1
