I've owned the B&K MC-101 Sonata, Classé CP-35, CP-40 and CP-50 paired with a CA-300 amp. The CP-50 is a significant improvement over the CP-35 and the best of the lot. I concur on the recommendation above of DR-5, DR-6, CP-50 or CP-60.
Classe' Preamp comparisons
Anyone ever had the opportunity to compare some of Classe's preamplifiers? Specifically a CP-35 to say, a model Five? Or how about either of those to a CP-50? I'm not sure of the Classe' history, but I do know that I like their sound. Just wondering which units really give the best sonic bang for the buck. I currently run a CA-100 amp into Maggies 1.6's and it seems to be a good match. I have a CP-35, but sometimes think there's something lacking....
