if the cd player's volume control is on the digital side, I wouldn't use it. You'll lose sound quality at anything except the highest setting. If the volume control takes place after D/A conversion, go for it!
Wadia 302 CD Player- Into power amp directly ?
I recently purchased a Wadia 302 CD player and have been using it with my Pathos Integrated amp, using the pre amp section of the integrated. I was reading that the Wadia can be connected directly to the power part of the amp and bypass the pre-amp. Does this typically improve the sound of the system? The pre amp section of my integrated has tubes. Do most people who have a cd player that can go directly into the power amp bypass the pre-amp? Any thoughts would be appreciated.
