I have the JC-1s, and was using a CJ 17. The move from that to the Ayre K1x was huge, one of the best pieces of gear I've bought. Another thought might be the Aethetix Calypso if you gotta have tubes. Don't be afraid of the K1x thought because it's solid state, it's anything but forward or agressive.
Preamp Recommendations for Parasound Halo JC-1's?
Just purchased my JC-1's and love them. Looking to upgrade from my CJ-PV10A. Any recommendations? Thanks.
