Hi guys, I need to get a 500 watt plate amp to power a computer sub I'm building. Parts express has 2 that will satisfy my needs: http://www.partsexpress.com/pe/showd...number=300-752 http://www.partsexpress.com/pe/showd...number=300-806 They are similarly priced and have similar features, save for 2 points. The bash has infinitly variable phase from 0 to 180 degrees. The Dayton has parametric EQ and a 0 or 180 degree phase switch. I don't know which would be more useful, the highly variable phase or the paremetric EQ, what do you guys think? This will be the deciding factor for me.
