Here is a slight twist, have you thought abut using an amplifier with a volume control? I am using a David Berning ZH-270 amp with an Electrocompaniet EMC-1 cdp and I am getting very good dynamics, detail, and resolution (overall, better purity). My speaker is fairly efficient at 91 db/8 ohms (very linear).
I agree with Drewfidelity that there are many variables when you introduce another component, such as a pre-amp. I don't really believe there are any components that are totally neutral so, the introduction of a pre-amp could be either pleasing or disturbing to your taste. Certainly, a good pre-amp can provide more drive and dynamics (especially when using long interconnects). Some use a pre-amp to add a certain flavor that are pleasing to their taste. As they say, different strokes for different folks!
I think it would be a tremendous advantage to audition equipment in your system to determine your personal preference.
