Hey guys, So, Im thinking about upgrading my receiver. I just feel that I could be getting better sound out of my speakers if I upgraded. Currently I own a Kenwood vr-6070 100x6 receiver. Im just unsure if now is a good time to buy. Im really interested in improving sound quality. Use is about 60% music 40% movies. I have a 5.1 setup with Fluance SV10 towers, SV6 bookshelves for center and surrounds and the Dayton 10" sub. This is what im considering right now. http://www.harmanaudio.com/search_br...0630-Z&status= After typing that Im wondering if the $500 MAX I have allocated for this upgrade would be better off put towords a new sub. What do you guys think I should do?
