I was using an htpc for playing ripped blu ray movies, but for playing from the actual disc a standalone player is more user friendly. I am 2 channel only and using an idsd dac which has both usb and coax inputs. I love the ease of use of the standalone player, but the sound quality of the pc movie audio running usb to the dac is MUCH better than the standaone player running coax to the same dac. Everything else is the same - same disc, settings etc. Any explanation for this? Don't want to go back to using a pc to play movies. Many thanks.
