I own a couple of big buck,pre's CAT3 and First Sound. If you can get your pre within 1 mt. of your amps;and if your cd or dac have 3v output the Placett Pasive (1k, used) is all the pre one would need.--Just my opinion.
Narrowing the Search
Looking in the Gon and have narrowed on three Pre Amps that seem somewhat similar. Classe CP-45, CJ PV12-L, and the Classe Audio Six R. Any opinions of one over the other and in particular the Classe Audio Six R. Not much background to be dreged up on this. As always, your thoughts are appreciated. Thanks, Dave
