Well, I have had an interesting experience with a JC3+. It overdrove my Bryston preamp because the MM gain was too high. However the lower gain phono stages work great with it such as the Pass Labs Aleph Ono, Musical Fidelity NuVista Vinyl and the PS Audio Stellar Phono Preamp. I love the Aleph Ono. I considered moving up the Pass Labs line but Wayne Coburn increased the MM minimum gain and that was a no-go for my Bryston preamp. I could go to the Pass Labs XOno. But haven’t found the right opportunity.
