Greetings from MN! My Yamaha RX-V373 AV receiver has never done very well with 2 channel TV audio from my Altec bookshelf 887A speakers, especially when it comes to voice reproduction. (Tivo Bolt with a Comcast cable card). I've enjoyed stereo since the Ventures Telstar album came out, but when it finally came time to buy an HDTV I thought I had to buy an AV receiver, and that it would do just fine pumping out 2 channel audio. Heck, it's got EQ and what else do I need? Stupid, yes? Anyway I seem to have found a solution: I'm ready to order a Nero-XD 200W HiFi DAC 2-Channel Class D Stereo Power Amplifier. It has Optical audio inputs and analog. Should I connect it to the Optical Audio out on the Samsung plasma TV, or the Tivo Bolt? The Tivo has both analog L/R out and an optical connection. Will one work any better than the other and will there be any problem with audio/video sync Or should I consider some other setup. (The smaller footprint of the Nero is also appealing and an FM tuner section isn't required.) Thanks!
