I too was considering a Mac MR 85 but for some reason, can not find any reviews on it either with our fellow Audiogoners or any other site, including fmtunerinfo! Very strange. I have SF Piano home editions with MF A5 integrated, and using an old but good Vector Research 7000 as my tuner. Want to experiment with something else, either tubes or ss, but don't know what to do as I am still a relative newbie in these matters. Apreciate your take. Thanks, Alan in NY
