Hey guys, i have a pair of b&w 604s3. I currently have them hooked up to my yamaha rx-v2300..Would the speakers sound any better on a parasound amp? Im thinking about buying a hca1000a....the receiver is 100w at 8 and the amp is 125w at 8.....I guess i want to know how different is the power? Is there a big difference from the receiver power vs. the amp power?, thanks..................
