I like ATI amps. They are built like Soviet military hardware. I don't mean tubes, more like tanks. But, ATI amps also have wonderful sound quality.
I'm a fan.
On the other hand, I am not a fan of the Outlaw monoblocks and an Outlaw processor. My friend picked up a bunch for his 5 channel surround and to my ears the monoblocks sounded flat with a pair of Michaura M665s (like M60s) in front, a pair of Michaura M55s in the back (like M22s) and a customized center channel with a Merak cabinet and a pair of Axiom 6.5" drivers and 3/4" titanium tweeter.
I used the same speaker kit with a Sony TA E9000ES processor and Anthem PVA 5 amplifier. Sounded wonderful.
