@audiosens - I can't say if it will sound better, to you, in your system. I can only share my opinion, based on my direct experience. I've tried on at least a couple of occasions to replace a dedicated CD transport with a high-end DVD player as the transport, connected via coax, to a DAC. On both/all occasions, the transport sounded better to me. Not immediately noticeable. However, after listening for a bit, I always found the transport to be more open sounding, etter distinction between instruments/voices, etc., more airy, better soundstage width and depth.
It has been several years since I last attempted this, so things may have changed with more modern DVD players. However, I doubt it. With the exception of Oppo (no longer in production), DVD player manufacturers seem to have become less concerned with 2-channel music playback.
