I'm thinking of upgrading my entry-level Yamaha receiver. It works fine, but at higher volume levels the sound is a bit harsh. I'm basically looking for something with very clean sound, I'm not very interested in lots of other features. I went to the home theater store here locally, and was interested in the following models: Pioneer Elite VSX-36TX $999 Pioneer Elite VSX-41TX $599 Denon AVR-3802 $999 The salesman told me that the 36TX has Burr&Brown DACs whereas the other two do not. I've heard that these are very good DACs, but I don't know how much impact that has on the sound. Can someone tell me the pro's and con's for these models, or suggest something else in the same price range?
