Wow, this amp rocks and I can highly recommend it for home use. It will last you a lifetime more likely than not. I was doing some pretty loud listening last night for a few hours and the fan didn't even come on. These things are designed to withstand 95 degree heat outside in the sun and can drive a 4ohm load full tilt. Many have no problems driving 2ohm loads in stereo with it. For looking so small and petite it sure packs some weight a lot of power. Yes I could hear differences in this amp and my AVR. The amp, probably due to some much headroom, easily drove the bass woofers on my 3.5 way 4ohm speaker with authority. Very, very nice amp for the home user and a lot cheaper than those Krells and such.
