The CD player on the MF CD PRE 24 is the Nuvista without the tubes. See Fremer's review .
I also have the M3 and had the TriVista 21 in the past. I actually like the V-DAC better than the 21, especially with a Little Pinkie power supply. I would forget about matching looks and get a Metrum Octave; you may find yourself listening to CDs seriously. It is very small but quite attractive and it the best digital I have heard by a considerable margin.
