I am not going to claim to know the exact usage. I purchased it from Mehran, who had stated that it had about 100 to 150 on it when I bought it, that he had received it on a trade-up, and had sent it back to Japan for inspection prior to selling it to me. I would estimate that I then used it on average an hour or two a week for about 3 years. So, maybe 400 hours total?
My Audiogon userID is also wdi if you want to look at my feedback there.
