@almarg , thank you so much for coming in on this conversation, I was hoping you would. I did not get the owners manual but have requested for one to be sought out for me from a friend of a friend living in Germany so that should be forth coming. The dealer I bought the Wall from is listed as the only U.S. distributor, Highend Audio in California, and he seems to be dropping the line, this was his floor demo, which I bought for a song. He stated the mm @ 45db gain, and the mc @ 64 and 70 db of gain.
