Right now I have 4 possible places to play a CD in my system. Yamaha cheap 5 disc changer, nice sony 400 disc changer, Yamaha CD Recorder and a Yamaha DVD player. All 4 are connected to an rx-v1400 via optical connections. First of all, does anyone know if any device will play a cd better than the others. I figured that because they dont do any decoding, it's all just about equal. I can't hear a difference. Also, is there any reason to spend money on expensive optical cables? 2 of the 4 optical cables I use are the stock ones that came with the units, and I can't hear a difference between them and the $20 acoustic research ones that connect the DVD and 400 disc players. The cables are all very short so I can't imagine there's much of a difference between cheap ones and really good ones (atleast not that I can hear). Any clue?
