Feedback: I've listened the 2105 and C-28 for several hours since returning home. They sound great. Thank you for getting these done ... and doing such a fine job. I appreciate your help and will certainly pass on my experience to others looking for McIntosh pieces to be worked on. D.C., NC
I received my MC2105 on Friday and just have to say the packaging was incredible and as a result arrived in perfect condition. I hooked it up and all I can say is the sound is amazing in comparison to what I had before. It is amazing what you guys were able to do with this amp. I could not be any happier with the work or service I have received from you guys. J.F., WV
... you provided impeccable, professional service for one of my most prized possessions, my McIntosh 2105 power amp. I really appreciate your friendly, professional help and care that you gave to my Mac. The 180 mile drive was well worth the time, as you and Ernie really made me feel at home. I wish I lived closer. Audio Classics is McIntosh heaven!!! You and Ernie made my day, .... it was so nice to get away and devote some time to my audiophile passion. The McIntosh factory tour was a dream come true for me, as I have wanted to do that for a very long time. Thank you again for calling them and setting up the tour for us. I look forward to doing more business with your great store in the near future. T.G., PA
Andy Butts is a very nice person who help me out with my MC-2105..I really dont know what i would have done without him...Very helpful,supportive and very patient with me...Great Great job guys!!! Keep up the Great work!!!! M.M., NY
C 28, MC 2105, MCD 7000 I'm speechless....... Popped in Beethoven-Sonaten CD, and just sat frozen, in complete disbelief. It was great to meet you, see the store and talk to all the nice folks that dropped in. Excellent equipment, first class service, everything I expected and much more. Many thanks to you, the engineers and staff, I'm a very satisfied customer. S.B., PA
you don't know how much happy i am. I enjoy so many years my pre-amplifier c-28 & amplifier 2105, with a mr-74 tuner recently. I like THE MCINTOSH SOUND, life-like !!!!! And the look, of course, especially the movement of needle in the blue eyes at my 2105. A MCINTOSH cd player for me is a Dream that comes true . At Shows in belgium ,i 've seen a McLaserdic playing a movie and recently i 've heard a Mc Music Server BUT NEVER NEVER heard a MC CD PLayer (including never seen one in the OFF position also in the store where i buy the book) !!!! As I could read on the web, K/S cables are amazing! I will discover these cables (not available in store outside usa/canada) who impressed so many HiFI brands! A VERY SPECIAL THANKS for your good advices, your help in this transaction, and other people working @audioclassics who can convert the CD player to work on 230 VAC giving so the chance to guy like me living outside USA to own MC products ! And of course your family who MADE HIFI HISTORY !!! V.M., Belgium
... i got it! Its fantastic, seems to be perfect, like new, the package was incredibly strong and very safe, ... Thanks for the bulbs and for anythings...im excited!!! R.R., Italy
Haven't bought from you in years -- but have been totally enjoying my MCD-7000, C28 and MC2105.... J.D., CA.
I unpacked and installed my (McIntosh MC) 2105 this weekend and am delighted with the restoration that you did. First of all the packing was incredible. Not even UPS on their worst day could do anything to it. Once unpacked the unit looked virtually new. You had stated that it would be up to minimum factory specs, and after installing I could not agree more. I am now hearing things that I think I was missing for years. After this experience I would not hesitate to use your service again. Thanks for the good work. B.O., AZ
