I have a Theta Miles (balanced version = $1400 used) that has an analog volume control and drives my BAT VK-500 really well. Impedance between the two components seem to be no problem. It is definately better than when running through my Forte Model 2 preamp. Part of the problem may be that the Forte has only RCA outputs and the BAT XLR inputs. I convert with a AQ Lapis 3 RCA to XLR IC. I don't know how much this conversion process degrades the signal.
I think the general consensus about driving amps without a preamp is that it provides more detail and clarity. Many people seem to prefer good preamps in their systems because they provide more bloom, dynamics and overall magic to the sound. I'm sure a big part of this depends on the efficiency of your speakers, the gain of your amp and the output of the cd player or DAC.
I would definately give the Theta Miles CDP a listen in your system.
