No I don’t, wish I could, in Australia they are over $18k. And to buy a s/h pair in the US is cheap enough, but shipping for me is a huge cost, and then I’d need to convert them to 240v, but this could be just a primary transformer tap change if lucky.
I have something similar two pairs of ME850’s (long out of production) but very similar topology to the JC1’s.
My reviewer friend Edgar Karmer for HiFi Australia, 6Moons, and who also owns Audio Esoterica magazine has a pair of JC1's, and they were the best thing (beside an ME1500 also out of production) we found from many to drive his Wilson Alexia’s with, which are also a bitch to drive.
