If I absolutely had to replace my current AVR right now, I'd get the Integra and
Outlaw Audio
Taxi has the Integra, and it seems to work pretty well (other than being slow on aquiring signals via HDMI). Another friend of mine has the 7075 and it absolutely rocks. Don't shy away from the rated 75 wpc... Look at the power requirements for this amplifier compared to any receiver that you're looking at... this is a tru 75w of output. Also remember that for each 3 db of output, you're looking at doubling the power requirements. So, to get an additional 3 db of output, you'd need an amp with 150w, to get 6 you'd have to have 300, etc...
