Hey gang, I have a MegaBass SS rackmount head that I've had for years thats done excellent for me. Great tone and it's really LOUD to be only 200w X 2 (each side). I know however though as I add cabs and if I do a larger venue or play outdoors I need to push the Avatars I'll be feeding. B212 and a Pro410. Both 8ohms. The P head (rackmount BTW) has all the versality and input/output jacks for adding power sending power, xlr, send/return loops, etc etc etc... It seems like the only bad thing about it is it has that "P" word on the front! Enough said, what are some opinions to POWER UP? QSV RMX2450? Carvin DCM2000? I need to stay in my budget. THANKS!
