Using CD player without Preamp?

No. The best preamp is no preamp. The only thing you may be missing is other sources of music. Phono, tuner, tapes, equalization. If you're happy with your system, save your money for more music instead of electronics. I myself, like all the other sources, but that's me. You have nothing else to degrade your sound the way you are set up.

There is another post on this subject from a few days ago. I agree with Polk as long as the output stage was actually designed to drive a power amp. Despite having a nominal output high enough many CD players will not be as good as a good preamp in driving a power amp. But if they have been designed to do so then adding anything else will degrade the sound to some degree.

yup,old business,check out the recent thread.....good luck
