OK - forget that quality of music is a subjective matter. I have a Denon DVD1920, and a Denon AVR2805. I also use good quality interconnects. I like to listen to a lot of stereo music, and i'm currently unhappy with the sound of my setup. I have tried analogue and digital connections between source and amp. Is it worth me getting a DAC, or is my amp a lost cause for stereo? I was thinking of an M-Audio Superdac. Any opinions?
