I have the 5000 in a bedroom 5.2 setup and it's a great little amp and does an excellent job of driving my 4 ohm speakers!  This 7220 sounds like a excellent home theater amp with solid 7 channel power and a 
fully differential design  from Outlaw/ATI.  Though as with most of these high current 7 channel amps you'll need a dedicated 20A circuit to get the most out of it.
I hope the fans can be easily user replaced as an amp like this from Outlaw will last many years and having the fan bearings wear out is a god awful sound that I'm dealing with on DVRs that needs them replaced and I can only find ones to spec direct from China. I'm using external 2 TB HDs and if I swap out the whole DVR I lose all my recorded content - Star Trek and all 
Also on Outlaw's website it states the * Introductory discount prices & Free Ground Shipping to the 48 states are only valid until
