CD player straight into amps?

I have had a Wadia 830, 850 GNSC, and now a Camelot Uther, all of which were run directly into the amps with great success. I used to own pre amps, like BAT, Sonic Frontiers, B&K, that were nice, but the sound directly seems more refined and accurate in the mids in my system.
Give it a SHOT!!!!
