The 7075 may not sport as high a rating as many of the big receivers, but it's power supply is likely larger - meaning there's more current available, which is generally going to be to the speakers' (and your ears') benefit. It will also be better able to work with low-impedance loads, something that very few receivers are designed to do. Unless you are running significantly difficult loads that need a larger amp (the example that I saw cropping up around here a lot a couple years ago was Polk's LSi15), the 7075 could be an excellent balance point between price and sonic performance.
