i've owned the Playback Designs MPS-5 CD/SACD/server dac digital player for almost 4 years. it has an Esoteric disc drive, and has multiple digital inputs so works great as a music server DAC.
if you are considering those players i recommend also checking out the MPS-5.
i'm really into analog and have 3 high end tt's as well as a couple of RTR Master recorders. the best thing i can say about the Playback Designs MPS-5 is that it's the first digital that can hold it's own in my system against the analog. click on my system page for details.
also; the dac in the MPS-5 is programmable, so it's as future proof as any digital i've seen.
the EMM Labs and Esoteric make high quality products too, so good luck on your search.
btw, i'm not a dealer. :)
