I need the more better digital

Red book spec digital cannot provide you with what you are seeking. My advice is to go with a SACD player. The lack of music is a serious problem, but the sound quality is reputed to be better than any available red book playback. My experience with SACD is that it's equal to my RPM/Benz/JRDG analog rig.

The Theta Pro GenV, while not as good as the DCS, is certainly more affordable. If you want smooth, then try listening to a Bel Canto dac. It is not the last word in resolution, but if you hook it up to a good transport like a CEC, with a jitter reduction device, it sounds pretty smooth. It is also really cheap.

Didn't like Krell, Classe, or Wadia? Are you sure you like digital at all or is the price/performance of those high dollar pieces vs the more real world, say maybe 1-2k range of players the issue? Maybe the SACD format will float your boat a little more, kind of limited on the software right now though.
