My sony receiver is not the best one, but also not the worst one. Since I already have denon receiver in my dedicated home theater, the Sony will be moving to my bedroom and i will use it for a while. I don't know the difference in DAC quality between Sony and PDM320, but PDM320 is described as a pro-cd player and the price is not too expensive. Well, I think i'll get a cheap dvd player in stead and use digital out. I'm thinking of Pioneer 536a or denon dvd-910.

thanks for all comments.
