Hi, I agree with the other posts about the superior sound of the old Mac tuners compared to the MD's. I have a MD-102 in my system upstairs and it sounds fantastic on the jazz and classical stations I like. The rock stations I like don't tune in as well, that is not the 102's fault, it's my antenna and geographic location. However, I bought a Mac MR-67 on ebay ($600) and bought NOS Telefunkens for all the tubes except the 6AU6s in the IF section and now that is my absolute best-sounding tuner. I also have a vintage Fisher 350-C and a Meridian 204 and an old Marantz 2110. The Mac sounds incredibly good, and the MD102 is a close second.
