WRECKA/Inspinout,
I don't know anything off hand about each of the amps you are referring to. I do know they are both high qaulity, have similar specs and similar retail prices. As far as spending 750 for a 450 watts amp....well, prices are mainly established by the type of amp. If you get a class a/b amp, it'll cost you $1 to $2 per watt. While class D will cost 40 to 50 cents per watt. This is where the big variation in the price of amps comes from.
