Classe preamps

I liked the CP 30 I had, built very well, with a full powerful sound. The phono stage was good too.
I would go for the newr rather than the older amps. Also consider the integrated CAP-150 or 151, very good value.

I have older classe' DR9 amp and DR6 pre-amp (purchased via audiogon)and they are built like tanks and I believe sound far superior than the newer classe' gear.

I have a Classe CA-200 and a CAV-75 amp for surround. I think they sound awesome. The 'Classe Sound' is rich smooth midrange with clean smooth highs. The bass is full and deep, although I've had other amps that were tighter in the bass and more detailed, but the Classe wins overall because of the warmth in the midrange. Vocals are awesome. Don't pay too much attention to the audioreview reviews, if you notice many of them seem to be people that hate Canada. Maybe they are threatened by the compatition. I read these too and they made me nervous, but I'm glad I ignored them. The sound is excellent and build quality beyond reproach. Good Luck.

I have the classe 6 preamp and think they represent great value at $1000 or less on the used market. I talked to classe about their more recent models, of the ones you mentioned they seemed to prefer the 47.5 over the 30 45 or 50.
