Gerryn - I preferred the Mephisto to the old Capitole and the appearance of the new Capitole doesn't excite me - neither does the price tag!! Yikes!
Actually I saw a new Capitole (MkII) being sold on Audiogon today for 5500.
I am not terribly familiar with the Classe' CP-60 preamp. So take my suggestion with a grain of salt... kay? In a case where I had a solid state preamp, I would run the Capitole directly to the amplifier.
With the Capitole, you are speaking about one of the finest CD players in the world. So when you go to connect it to a preamp, you must also ask yourself, "Is this preamp one of the finest in the world?" If not, I would be affraid of using the pre simply because it could strip away some of the Capitole magic. Of course you have to try it both ways to see which you prefer. Less magic may be a good thing! :)
Make sense?
I have a VERY resolving preamp and in my system, the Capitole sounded better with it vs. its own volume control.
