Hey Teajay, thanks for reaching out. I purchased the copper version and it is currently being built. I didn’t choose copper particularly because of the price difference but because I have not read overwhelming consensus that silver is better wrt AVCs.
Arek knows me as a long-time customer so, if you are game, maybe we could ask him if we could swap units after your review and then we could both directly compare the silver and copper versions. We could even schedule the hand-offs so that each of us would have both units in our houses at the same time for a week. It would require him to treat both units as demo models and I would commit to either staying with the copper version that I already purchased, or sending it back and upgrading to a silver version, either the demo unit if you don’t buy it, or a new unit. Of course, I would do Audiogon write-ups on both and the comparison. Let me know if that sounds interesting to you and, if yes, we can reach out to Arek.
