I can't decide which of the following 2 options I want to do as upgrades: Option 1: Price: app. $1100 Sell my Yamaha HTR-5550 receiver and keep my Sony DVP-NS755 DVD. Buy the Sony STR-DA4ES receiver and a Denon DVD-1600. Use the Sony exclusively for SACD playback, the Denon for DVD-A and Video. Option 2: Price: app. $1400 Sell both my Yamaha HTR-5550 receiver and Sony DVP-NS755 DVD. Purchase the Denon AVR-2803 and Denon DVD-2900. Use the DVD-2900 for everything that comes on a disc. What do you all think about the two options? I really am torn between the two options, both receivers sound great to me on my Boston Acoustic speakers.
