Thank you for the quick turn around and your personal attention in getting the tuner back to me in a timely manner. I had a chance to listen to the unit last night and this morning and it sounded terrific; as it had 15 years ago when Richard Modafferi did his magic on it then - with the Modafferi Mod. Stereo imaging is crisp and detailed. Hum is no longer a problem. Everything sounded “just right”. Within a week of me sending the unit back, I was surprised to get a call from Richard Modafferi himself... explaining the tuner problem and what he had to do to repair it. Please thank him for me and let him know how happy I am with the result. I want to thank Audio Classics and its staff in serving the audio community. Thank you for having the knowledge and know-how in repairing classic equipments (like the MR71) for audiophiles to enjoy. Please accept my sincere thanks to you and your staff for the attention to detail and for the services you provide. Happy listening and look forward to doing business with you and your company again. D.Y., NY

RE MA230: It sounds like a million bucks! Thank you!! K.K., OH

Now that I have had my Marantz 10-B home for a month, I needed to tell Richard Modaferri and you how pleased I am. As I may have mentioned when in your shop, I got into the hi-fi hobby in the early ‘60s when I was in my early teens. I purchased the tuner new in 1967 and have always considered it my most valuable hi-fi possession. Knowing the complexity of the unit, my concerns over the years have always been who could work on it. Aware of Audio Classics’ reputation for vintage Mac and Marantz equipment, I always suspected you were the place and finally just made the phone call. There are other people out there who say they can work on 10-Bs. However, knowing of Mr. Modaferri’s fame with his MR-78 and other products, I was relieved that he could and would work on it. As you said, it is now good for the next 50 years. I will have to let my daughter (who when little would sit in front of it when I turned it on and clap when the STEREO light came on -- and who today has a vintage Mac system purchased from your store) cross that bridge. Again, many thanks to you, Audio Classics and especially Mr. Modaferri. JE, ME

RE Marantz 8B: I received my amp today and hooked it up, all is well. Thanks to George for doing everything I needed- I failed to mention I needed a new power cord, but he did it anyway. Great packing, very impressive turn around time, you guys are the bomb- D.Q., IL

MAC1700: Just a note to let you know I received my receiver last week and it sounds terriffic. Nice Job! R.P., CA.

I just received my Marantz 10-b and you guys have shipping and packing down to a science. ... I am very satisfied with the repairs and alignment done to my unit. Thank you. P.N., CA

My appreciation for the good workmanship of audio-classics . It also applies to your repairs. Thank you very much for the way you conducted the handling of the repair. It sounds as if it was new. H.G. Australia

...the c32 you repaired for me sounds great ,good job. I do think that replaceing all those alum foil ribben cables could make this one of the best c32 around. Again Great JOB W.B., MI

Just wanted to let you know that my refurbished MC2100 arrived safe .... I set it and the 2100 I recently bought from AC up in mono mode over the weekend. The sound is just wonderful. Thanks for doing your usual excellent job. It is obvious that AC treats this old Mc equipment with a lot of TLC. It was great finally visiting your shop and meeting you face to face. Looking forward to the next visit. B.J. TX

I am very happy with the service you and your service dept done on my mx-113. Very clean and sounds great. Thanks for dealing with me and for have patients. To you and all of the service dept, I just wanted to say great job and thank you for a wonderful service. D.C., IN

....I had the pleasure of having several of my Mc Intosh components serviced by your fine company. I was very delighted by both the quality of work and prompt turnaround. A.D., NJ

Just wanted to let you know that your employee, Ryan Kilpatrick, has been a great help in setting up my equipment. You are very lucky to have such a nice guy, never gets uptight, stays with it till it all comes together. I cannot say enough just wanted to let you know. Thank you. J.H., AZ

Thanks for the help on the phone today. I followed your directions and the amp works great. I spent the afternoon listening to music and love the sound of the amp. Thanks again and I look forward to doing business with you again. A.G., VA

The MA5100 is back safe & sound. .... As we hear the warm, delicious McIntosh sinuous waves, we both thank you for your expertise and the very timely repair and delivery of our unit. In closing, we will never quite understand the lemmings who migrate to the new toy store to purchase their inevitable listening displeasure. The MR65 will follow shortly for you and Modafferi to give your special attention to. R.S., PA

I have received my MR71, given it some burn it, as it has a lot of new parts, and now feel that it is fully burned in. My thoughts on the Unit follow: 1. Magnificent sound quality - it has returned to its Marantz 10b killer status. After break in, I came into my house and heard in the living room Bach's Unaccompanied Cello played by Starker. I have the original Mercury album by Starker and frequently play it. I immediately accused my wife of using my TT to play the Mercury Starker, as it sounded so close to the LP that I did not think that it could have been FM. I have asked my wife to stay away from the LP head end and was initially cross with her until pointed out to me that the TT was not operating, that the same Starker album was on FM. I was surprised as the Starker album sounded on FM so close to playing the original LP on a super tweaked TT/TA and cartridge that I could not hear anything that told me that it was FM only. I believe that this story says it all. 2. Stereo separation and selectivity - excellent. Please give my thanks to Richard for having done his magic again with my Unit. Each time he has it (three times now) it comes back better than ever. G.M., NY

As I wrote earlier, our MA6900 encountered the same sort of failure that others have described - a sudden loss of output, with both meters pegged at the top of the scale, and both powerguard lights on. After discussing the issue with Audio Classics' Ryan Kilpatrick, my wife and I decided to make the three-hour drive up to Vestal with the amplifier... Ryan was ready for us when we arrived shortly after the store's opening, and he immediately went to work on the amplifier. We relaxed in one of the sound rooms, enjoying a superb McIntosh system, and in short order, Ryan confirmed that the problem was a faulty capacitor, and he assured us that he could complete the repair during our visit. Ryan also let us know us that he had quickly arranged a private tour of the McIntosh factory while he made the repair on our amplifier! At McIntosh, we met Chuck Hinton, who took us through the factory, providing terrific background information, and kindly answering our many questions. We got to see transformers being potted, as well as the fabrication of those famous glass faceplates. Chuck concluded our tour with a listening session in the McIntosh theater, and words just are not adequate for the experience - what a system! On returning to Audio Classics, Ryan had the amplifier wrapped, and ready to go, confirming that the repair had been successful, and our trusty MA6900 checked out perfectly. In a nutshell, this was the single best customer service experience that my wife and I have ever enjoyed - far beyond anything that we expected, and clearly a standard for others to shoot for. Ryan and the folks at Audio Classics could not have been nicer - they are genuinely friendly people with a passion for their work, and a high regard for their customers - their relationship with McIntosh is quite special, and it shows.We join the many who sing their praises - thanks, Ryan, Chuck, Audio Classics, and McIntosh! S.E., PA

Just wanted write and tell you that George did a great job inspecting and servicing my MC 7270. Plus he was a treat to talk to for a while and most hospitable. It may have only been some minor oxidation on the input level switch but cleaning it and the input level paths seems to have added new life to the amplifier. I use Legacy Audio Focus speakers and they have never sounded so good. Thanks again and see you next time. D.C., NY

Just a short note to thank you for the exceptional work you did on my MAC4100 Receiver. It sounds absolutly wonderful, as good or better than when it was new. Not only that, but it looked new too. I was somewhat concerned sending my Mac to NY from Kansas. Needless to say that was not a problem Thank you and your team for the outstanding work. C.K., KS

Just wanted to say thanks. The Marantz 3s are killer once again. In addition to playing vinyl and fm, porn bi amped is the only way to go. actually bi-bi amped porn is something that you need to experience. R.B., IL

Not that I ever had a single doubt. I've been dealing with you guys indirectly since the mid 80's and nothing but 1st class. Now I have to admit 700.00....plus shipping is a LOT more than I figured to spend on this old dog..considering the big parts had already been replaced. ....BUT it IS totally spec! I have a hearing loss in my left ear from stage monitors...43 years of rock and roll....My loss is in that 3.5k snare drum trauma range....but I must say today I feel like you gave me back some....this amp NEVER sounded this good. I do have pretty good high frequencies surprisingly enough and there are transients in the left speaker that haven't been there...in 20 years. ....It suspiciously looks as if you put some really nice preamp tubes in there....all matching yellow print sylvannias....me likes! Whatever unknown extras I sent were well worth the outcome. Thank you so much for being a first class operation, and if the other one ever gets dodgy enough for me to warrant the expense....or if I have a windfall....you know where I'm sending it! Great box too! I'll just hang on to that in case.T.T., TX

Long overdue "thanks" to helping resolve the C2200 issue! It's been back for a couple weeks and performing flawlessly! J.M., MD

....have not talked to you in a while. But as I listen to my system I can not thank the staff at Audio Classics enough. I still marvel at the quality of the sound. But then again, its a McIntosh. G.B., IN.

received MX113, it's perfect thanks a lot S.D., Italy

The amp arrived safely and I allowed it to warm up for a few days. Since then it has played brilliantly. It really does help to bring an amp up to spec. So thanks very much again for the high quality work. W.L., WV

I never would have believed how much difference an amp would make in my system. As a long time Audiokarma guy I always bought the wisdom that the speakers are the first place to spend money, and sources are second. I now know better! I really appreciate the service I've received from you (and the gang on Saturday, when I picked up the box). The amp sounded and looked way, way better than it did during my first visit, I believe new gels or equiv were done to the meters, since instead of faded and streaky they are now ballsy Mac blue. The unit really looks like it just drove off the factory lot instead of being 30 years old. THANKS!!! I can tell you one thing... I am done messing with Audiogon, eBay and CraigsList for used audio. You guys simply make those choices obsolete. Once again, thanks and I hope to see you guys again soon. C.L., NY

I just want to express my sincere thanks and appreciation for a job well done! My speakers have never sounded so good, and the amplifier is cleaner looking, sounding and more powerful than ever. Your quick turnaround time and flexibilty in drop off/ pick up situations is second to none. You have earned a customer for life! G.V., NY

Just wanted to let you know that the MR73 arrived intact, looks fantastic, and is working very well. I appreciate the hard work by Richard Modaferri and everyone else involved. Thanks for the terrific service! A.G., OH.

Thank you for all your help it is very nice to have someone you can trust and think highly of and respect their opinion on things and I like to listen to what you have to say so I can learn things to thanks again B.E. CA

As my restoration project of my late Father-in-law's McIntosh system draws to a close, I would like to thank your company for your patience and understanding while working with me. In particular, Ryan Kilpatrick has represented Audio Classics as a kind, receptive, and knowledgeable gentleman. He always demonstrated respect to me as a customer and to my McIntosh components while they were undergoing restoration. I feel fully confident in recommending Audio Classics to any one searching for a truly customer service oriented organization where quality can still be found in great abundance. T.W., MD

I truly appreciate your time spent and advice. The guys at Audio Exchange were definately positive in mentioning you all, noting your willingness and ability to source high quality gear, and your service & support. They were clearly placing you right on par with the factory itself for your service and support, and noted only a couple primary differences ... That you all were generally quicker and more responsive when it was within your bailwick, and that the factory was ultimately more capable of resolving it beginning to end when things such as laser & disc drive repair were involved. Both to be expected, I'd say. For my part, I will continue to recommend you all, and I have even more confidence and reason to now. Can't say thanks enough, E.C., VA.
