Tduffy1,
I'm in the same situation you are - driving an amp directly from a CD player. In my experience only, I have compared the CD->AMP Vs CD->PRE->AMP combinations within my system using an Audio Aero Capitole MKII SE CD player, First Sound Presence Deluxe MKII preamp and Art Audio PX25 SET amp.
Here's what I found:
(A) CD->AMP
* more detailed, for example it was easier to distinguish the words a vocalist was singing and mids & highs were a bit clearer -- this makes sense as fewer pieces in the audio signal path should be less damaging to the signal
(B) CD->PRE->AMP
* more bass
* more dynamic
The preamp section of the Audio Aero is very good and uses an analog volume control, but I suspect it can be bettered by either custom modifications to it or with a very expensive preamp. . .
I chose to go with the CD->AMP config as musical details across an entire freq spectrum are more important for me than a slight increase is bass and dynamics (as I'm using 97dB efficient speakers they're already quite dynamic). I can improve the bass amount and dynamics when I plan to buy a pair of subwoofers and put a high-pass filter ahead of the SET amp thereby reducing the heavy bass demands on it to improve dynamics.
Hope this helps in some small way.
