So here is my idea:\n \n Add a digital SPDIF input to my Sony DVP-NC650V player (similar to the popular NS500V). This provides several benefits:\n \n 1) I could play back my MP3s on my computer using 24-bit MAD decoder (and a 24-bit SPDIF stream), and get the best sound from Sony's 192(96?)Khz, 24-bit AKM DAC.\n \n 2) I could play CDs which I digitally extracted onto my hard drive (they are losslessly compressed w\/ Monkey's Audio). I could play them back through Sony's DAC--without ever using the transport!\n \n 3) No more shuffling CDs around! I could play audio CDs direct from hard disk.\n \n That's my pitch. So is this practical, or is it very expensive\/difficult?\n Leo\n \n PS: I have the schematic for my player.
