What processor competes with best preamp?


Are there any processors that will match sonically the best preamps when playing a good CD? Has anyone done a comparison or blind A/B and not heard any difference( assuming all other parameters were matched)?

Thank you John for your descriptive follow-up.I'm sure this will help others who have had my same thoughts.I will now upgrade my system to have the best of both worlds.
I'd suggest putting the Theta Casablanca with the Xtreme DACs on your short list to listen too.
I second the PRIMARE P30. Got one... love it. I'm all LINN activ except for the Primare. Bypass mode really does the trick. Not a lot of fancy stuff, just good clean sound. Check Simuko.com.
Stehno,I was curious.Why do you use a pre/pro with a 2-channel amp? My guess is so you can play DVD's but I was curious why you don't want center channel or surrounds.Thanks,Sherod
