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.

Many high end pre-amps due not employ a potentiometer as a volume control. Some use a high quality resistor ladder instead. So comaprisons have to be a little more detailed.
Everytime I've heard a comparison between a Wadia (or any other cd player w/volume control) direct to amp vs. preamp, I have strongly preferred using the preamp.
For what's worth, I'm using a 301 with a tube VTL 5.5 pre and a Plinius 102 power amp. And to my ears that's the best option. Í tried the "direct" option, and the sound lost some of its weight, soundstaging was flatter and became a little brighter. A lot of it may depend on your preamp. And if your power amp prefers direct feeds. Peter Thompson, from Plinius, says his amps don't like direct feeds...and he's right.
