You have to decide on tube or solid state. As a former owner of the CP-60, I can't recommend it highly enough. The best SS preamp I ever owned or auditioned. That is a very extensive list too, including the likes of Krell and Levinson gear. That being said, I've currently forsaken SS for tubes, namely a BAT preamp. It's not as flexible as the Classe, and the bass isn't as strong, but there is something about the way it handles vocals that has me smitten.
