Which integrateds have the best preamp section?


I've been reading "The Complete Guide to High-End Audio" by Robert Harley, and he places emphasis on the significance of a high quality preamp in getting the best sound. In my search for an integrated to drive my Sonus Faber Cremona Auditors, I'm curious which integrated amps have the reputation for having the finest preamp sections. Any opinions?

Conrad Johnson CAV 50 which essentially has no gain in the preamp stage. This is by far one of the finest integrateds ever made. Too bad CJ discontinued it. But they can be found used.
The pre-amp. section of the Krell KAV-400xi has received much praise in the press. I'm considering bi-amping mine with a KAV-2250 into a pair of B&W 803D.
