I'll probably get bashed for this but........... Every CD player I have ever heard (with a built in pre-amp/volume control) sounded better through a preamp. I have heard/done comparisons with the Wadia seperates, DCS stack, and my own Theta Miles. With a preamp in the system I noticed, across the board, a large increased in dynamics, soundstage depth/width and tone color. Preamps thet were included were CJ ART, Aesthetix Callisto sig, and ARC LS25II.
Hope this helps
