Feedback: I just wanted to say thanks for your great service on my c22 and mc240 that you restored ....The equipment sounds fantastic better than I would have imagined. But I hope that you don39t tire of hearing this kind of praise G.F. NY|
Just a note to let you know that my wife and I could not be more pleased with our recent purchase at Audio Classics. We drove up from New York this past Saturday with the intent of purchasing classic McIntosh vacuum tube equipment (I had purchased an MR67 tuner from you about five years ago). I have a very large record collection, over 20,000 LPs, and I was way overdue for a sound system upgrade. We spent a couple of hours with Ernie Schleider who was extremely courteous and helpful. He set us up in the listening room and left us to our own devices. I had brought along a dozen LPs, both jazz and classical, with widely varying voice and instruments for comparison testing purposes. My wife really got into the comparative testing mode and she played an active part in the selection process. After listening to three different MC275 power amplifiers, coupled to both C20 and C22 pre-amplifiers, we selected the MC275 and C22 combination that seemed to be producing the best sound. Of course, there is nothing like hearing the equipment in your own home and listening space. All I can tell you is that the equipment has exceeded our best expectations. The clarity and depth of sound coming out of the LPs is just spectacular. There is also a notable improvement in the sound quality of FM radio broadcasts. Bottom line: we could not be happier and we couldn't think of shopping anywhere else for this classic equipment. We should have made this purchase years ago and we sure are glad that we did it now.

You are a worthy humane cause to and for Everything McIntosh ! You did a fantastic job refurbishing my Dad' vintage 68' C22 Preamplifier and MC250 Amp which coincided with a personal visit to AUDIO CLASSICS, you arranged... a free MAC FACTORY TOUR and kept me busy ... while you did your magic to my McIntosh gear . ...."I DON'T FORGET A GOOD TIME by your presence and detailed efforts..!

upgrade Richard did on a C22....

performance of the C22....; so once
again thanks much. L.M., NY
