Yes it is a nice sound doing it that way...
I have make it that way with several products and it is really nice the sound that comes out, yes most of time there is less bass and maybe a kind of blurred edges in some instruments but with a nice combination CD-amp-speakers you can live with it and enjoy a minimalistic sorrounding sound plenty of openess and details...
I heard no blurring of instruments when listening to the Wadia connected to the classe amp and maggies. In fact I thought it was much more involving and resolute then the preamp they had on hand (some ML unit).
Bass was not at all lacking either.
From my limited experience in this area, I would say don't skimp on the type of direct control CD player you are hooking up to your amp.
Wadia, Cary, Theta and a number of other high end manufacturers actually intend for you to use the built in volume control so you can bypass a standard preamp altogether. Of course I think it might also depend on the amp so anything said here must be taken with at least two grains of salt. Maybe some amps require such high input signals that these players don't reach that level so the bass is rolled off and things get blurry...
Then there are those CDP's that have a built in volume control but it's not the main intent...it's just kind of there as a bell 'n' whistle feature...those certainly don't warrant getting rid of your preamp...
It always goes back to proper synergy when pairing up components. I could say the Wadia/Classe/Maggie combo is sweet but someone might not like Maggies and therefore has a pair of speakers that don't sound right paired with Classe amps etc etc...
It's all about experimentation until you've found that proper synergy...
I do believe that CDP's with specialized built in volume controls are a great way to go if you just listen to CD's.
Plus it's also been stated that you save on interconnects, power cords and can divert that money either back into a better player or more music.
