Ok, guys, should I bother upgrading my old receiver (Sony STR-de625)? I've it had for almost 8 years I think. The 'A' channel doesn't work, but that's no big deal since I can just plug into 'B'. I'm looking at either a Yamaha HTR-5860, 5850, or the 5890. It'll be used with a set of Boston Acousting reference series speakers, and an Athena sub. Also, a 32" sony wega flat panel I bought last year. Overall, I'm hoping to take advantage of the optical outs for better sound quality that I can use with my DVD player.
