don't buy rf on the net. Go to an authorized rf dealer and open up a few boxes, look at the birth certificates. You'll see that some of the 50x4 models did not reach max T.H.D. untill 800watts, another may have only hit 400 or 500watts. If you buy one on the net your likley to get one of the bad ones. I've never owned a profiel amp, but i can imagine my friends reaction (the guy with the P/G titanium amps) if i told him i bought a profile amp. :hilarious
