<font color='#000000'>Hi Glassman
Those are 2 very good suggestions. ATI supplies OEM amps worldwide (Outlaw audio sources their amps through ATI, if you compare the amps with the covers off they are identical). Adcom is a good company providing good value products. My recommendation would be to go with Earthquake Cinenova Grande 3 or 5 channel amps. I own a Cinenova 5 XLR and the output on this monster is prodigious. It weighs 120 lbs unpacked, and DOUBLES it's output at 4 ohms, from 300 to 600 watts! This has been verified by independent testing. It is super clean with pinpoint imaging. I use it to biamp my Axiom M80s, and could not be happier. Furthermore, they can be had at half or less than MSRP, brandnew from one internet dealer, whose link I can supply if you are interested.</font>
