After demo'ing the Yamaha YSP4000, I have decided to forego that option and go for a good 5.1 system. Here's where I'm at...
Sony 52" XBR4
Sony STR-DG2100 -- great features, matches well with XBR4, and great price at B&H
Definitive Mythos Gems for front and rear
B&W ASW608 Sub
Thoughts?
I am still working through the wiring options, but will probably use something like the Wiremold on-wall tracks to hide the wires to the TV. Has anyone used them and able to comment on how well they work and appear?
