I have had my Cayin for about 3 months now. I agree, it just brings out stuff I havent heard before. I had it driving my NHT VT-2's, amazingly it did surprisingly well, even tamed the NHT edge. Now driving GMA Europas it just keeps me enthralled.
CDP is a CAL CL-5. TT is a Music Hall MM-7, or will be as soon as the new one gets here, original arrived damaged. By the way, Walter at Underwoodhifi is wonderful to deal with, and is cross-shipping the new table, excellent service for a first-time customer.
I havent played with different tubes yet, but am looking at either EH or maybe Svetlana's.
