Amp was delivered today. What an incredible packing job. More importantly, what an incredible difference. It was a nice amp before...now its exquisite. Thanks!B.R.

UPS just dropped off my C26 and its back in its cabinet and on my audio rack where it belongs. It looks and sounds fabulous! A big thank you to you and AC for the always outstanding service! M.O. PA

Ryan and you crew just completed a restoration of my McIntosh MX110. They did an outstanding!! Job. I dont know what to say but thank you. Im utterly speechless on how beautiful it looks and sounds. Awesome job and much thanks. D.V. FL

Ryan finally got around to hooking the C1100 back up today. Everything works as it should... You guys are the best. I have and will continue to tell my friends and family what a great service you provide in both sales and service. M.H., MI

RE MAC1700 I39m on hour three of my return of my 1700 and I39m really pleased. I39m listening to a Grant Green CD I39ve played many times and CD playback on this unit has always been as close to vinyl as I39ve ever heard and the level of detail is really impressive. The improved tuner response has me thinking about putting a roof antenna up. I should have sent this to you sooner. Thanks. Have I mentioned that the phono playback sounds better than ever Nicely done. I owe you and the techs a beer. J.T. PA

Howard did a great job on the Rectilinears they are sonically perfect and I am happy to have them. G.S NY1310

I am really happy with the two repairs that your shop did for me in the past couple of months. The MR71 and the MC30 work great and I enjoy using them. Again I am really pleased with the repairs that Audio Classics did. N.U. CA

I have been listening to my refurbished 240 for several days straight through now and I am beyond pleased with the results. It was great meeting and talking to Ryan he did a an amazing job going through the amp top to bottom. It sounds better than I have ever heard it sound. not to mention super clean. The entire experience was top notch. Great customer service amazing store to visit in person Ryan and everyone I met were just awesome Also huge shout out to whomever packed her up for shipping you my friend are an artist You have a customer for life. D.D. OH

I wanted to follow on the return of my repaired MC2100. I39ve had a chance to blast through a few records and the amp sounds incredible. It39s obvious that the Audio Classics team put in a lot of effort to get this monster back on its feet and working out of both channels. HA From the Misfits to Lee Morgan to Ash Ra Tempel this MC2100 handles them all with ease and expresses sounds in every way a McIntosh should. Thanks again to you and the AC crew for getting my amp back in working order. I really appreciate it V.F. PA

I wanted to send a note thanking you and your team for the service done on my Marantz 10b. Richard39s work was incredible. Hard to believe you can get someone today with that level of experience and sophistication to bring a classic piece of equipment not only back to working condition but obviously better than it was when it was new in 1964 I am constantly amazed when listening to it now. It puts the other tuners I have to shame. The return packaging was excellent as well. I will certainly look to your group for my next audio service opportunity S.P. CA

Thanks youre a good PERSON I enjoy working with you C.R. IL

I have been listening to my system with my newly repaired MC1.2 kw. It is running fine. Thanks for your good work and excellent customer service. I knew that you would do a great job right from the start. I am glad I decided to use Audio Classics to do the repair. S.R. NY

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

I just wanted to inform you that I received the MR71. Everything looks good and the unit sounds great. Thanks for the great customer service that I received from Audio Classics. I will contact you again in the future if another one of my McIntosh components needs service. - N.U. CA

Your new technician who did my Scott 299 did a FANTASTIC job I am pleased as can be - the unit sounds as good as my way more expensive separate components including the phono section It drives the big Rectilinear III39s effortlessly and beautifully I am not parting with those. The Stromberg-Carlson 433 he fixed is also sounding amazing. I can39t tell you what a relief it is to have great service through Audio Classics G.S. NY

Thanks to you and crew for your continued after sale support. I always look here first for my latest gadgets. E.W., IL

My McIntosh MA6300 arrived yesterday as promised. You did a great job re-boxing the unit. I have it installed and running. It sounds great and works perfectly. Thanks again for your great work. T.E., MI

The MA5100 arrived yesterday afternoon. ...The amp sounds more fuller and deeper. ... Audio Classics has renewed my faith in the MA5100. The MA5100 is now performing the way it should. A big thank you to everyone who had a hand in working on my amp, and especially to Ryan and Steve who have been super to deal with. Thank you for everything you have done for my MA5100. AC continues to give superior customer service. T.G., WV

... my MC2125 that you worked on sounds great. I look forward to getting many years of great sound out of it. R.L, NY

... thank you and the rest of the team. ... I could sense and see the level of attention and caring put into restoring the two units. Cost is a factor with these equipment specially for someone new, and I did not quite know what to expect from them. I do enjoy listening to the radio and prior to the service the MR77 was disappointing but I had no idea what was normal. It now sounds absolutely beautiful and so does the humble MA6100. You guys are like Pediatricians as you cure our babies of their ails and put a smile on their parents! I hope you all enjoy the great work you do. K.A., PA

Thanks for the excellent service on my MC2505-2, it looks right now, functions correctly and sounds great. D.K., MI

I just have to ... tell you how great an experience it has been doing business with you guys. The excellent repair that Ryan and the tech staff has done for me on the Mac1700 receiver is just truly amazing and appreciated. You guys are definitely professional and know your business. The receiver has been totally brought back to life like it never has before. Power, realism, I can't thank you enough! Please feel free to use my comments on your website. D.T., PA

... thank you for doing the firmware updates…………….that is something that I wasn’t looking forward to doing! Not to get all mushy………..but I really appreciate the confident feeling of transactions with you and Audio Classics. I just don’t worry about it, knowing that your representations are always honest and full of value. S.A. TX

... I want to thank you for the work you guys did to it. .... I knew immediately the tuner sounded better but wanted to check everything out before I contacted you. You guys have refurbished that unit for me and I have purchased an MR77 tuner and MC2105 amp from you. I am extremely pleased with each piece and the fantastic sound I get out them. May be old stuff, but it sounds great to me. You have been excellent to work with and I appreciate all of your work and help with my various transactions. ... I could not be more pleased with the performance of the MA6100 and other pieces I have purchased from you. J.E., VA

I have to thank you for the EXCEPTIONAL service my MAC1700. It sounds better than new and the radio is sweet-sounding and clear. I realize it had been a long time since you looked at it and still you guys took great care of me. I will need speakers at some point and there is no other place I will look. Many thanks for all your effort it has been very much appreciated. R.C, NY

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..! R.R., CT

Mr. Modafferi created a masterpiece. Please pass along my compliments and thanks! That tuner just hauls in the stations and with it's great selectivity there's no tromping from other stations. Stations tuned in Normal sensitivity with flickering or non-existent Stereo indications almost always produce a steady Stereo indicator when switched to narrow or super narrow. Sometimes there is audible hiss and that can be cleaned up with filter selection. That tuner rocks! I'm listening to a low wattage Detroit classical music station now that required narrow and 1 step of filter but it is now crystal clear with great audio fidelity. It's antenna is 70 miles from me ... D.K., MI

I received the CD player after its repair and it is working fine. ... I convey my thanks and appreciation to both of you for the service and courtesies each of you extended to me. Again, thank you for your service and assistance with the CD player. J.G., NY

... my MA6100 Integrated Amp has arrived and is working perfectly. Thank you for your rapid response to my concerns. All of the people I talked to at Audio Classics were great. When all connected, everything was perfect !!!! and I mean perfect !!! T.Z., PA

The MR78 arrived at my office yesterday afternoon. Not being able to stand it, I took the rest of the day off and rushed home to hook it up and give it a listen. I read Richard's notes several times, and even though I am an engineer myself (ME not EE), I know my limits and admit that I don't understand all that he wrote. No matter, the tuner sounds good. I can't say how much better, as in before and after, but I can tell you that my favorite station is approximately 60 miles away and before Richard worked his magic it was listenable in mono, now it is listenable in stereo. I am very impressed. Please pass along my thanks to Richard. BTW, I sold McIntosh at stores in Seattle and San Diego for most of the 1970s and had an extremely high opinion of the MR78, but never could afford one, even on accommodation (starving student syndrome), at that time. It is a great privilege to finally own one and know that it is working at peak efficiency. B.S., FL
