I'm starting to upgrade our stereo system. I picked up a pair of Klipsch KG 4's and changed out the tweeters for Crites titanium. Now I'm looking to replace the 10 - 12 year old Pioneer surround sound receiver. So I want a 2.1 set up that I can listen to internet radio sources. The FM reception with our attic antenna is lack luster, and our local classical station streams its broadcast. So I'd like to try internet radio rather than antenna most of the time. I'd also like to listen to music in iTunes off my macbook. This receiver or amp will be connected to a turntable, CD player, DVD/TV. The system will get used primarily audio from DVD/TV and maybe an hour a day listening to music. I'm considering the Yamaha A-S501 vs Yamaha R-N602. Any advice would be appreciated.
