Feedback: This is great. i've taken the liberty of mounting my metz antenna on the outside of my townhome and i'm pulling in low-power, small college stations (and others) and using the functions on the MR-78 to enjoy stuff I was never able to (or knew existed) before. this tuner has redefined my feelings towards FM radio..... I told one of my younger friends about it and he was floored, he can't wait to come over.... I actually got a kick out of finding some tiny little conservative religious radio station in the middle of nowhere and listened to the preacher rant for a while as I enjoyed a nice cold vodka Mojito, thinking..... "wow, his voice is pretty clear and has good stereo separation!" Mr. Modafferi, you are the best. J.L. NC
Hope that all is well in Vestal. Please extend my most sincere congratulations to Mr. Modaferri and also to anyone else who worked on my MR-78. This is the best sounding tuner I have tried to date. Considering my location, that is one huge compliment. R.O., CA
finally baby is back home. It sounds wonderfully. My experience with Audio Classics was the best possible. Yous service was fast, professional, honest. I offered you the possibility to get more money: you did not take advantage. You charged me the freight you really paid, and did not charge the new box. Richard Modafferi did a wonderful job and an exhaustive report. Thank you very much for all of this, and for the joy I am feeling now. A.M., Italy
Another BIG thanks to the service dept. My MR-78 is back better than new. They did some major work on this unit last year. When it developed another problem, all got fixed under warranty. Like they say down here "Dont get no better than that" Thanks again. 73's J.Z., SC
The MR78 and MCD7000 arrived today. I just had to let you know how happy I am with each one. Not only do they sound terrific, the aesthetic value is absolutely first rate. I sincerely thank you. Your salesmanship and products are second to none. You've got my business for life! Thanks again. Sincerely, D.B., MI
The MR 78 tuner is truely a wonderful tuner and I am glad I got it repaired and modified by you folks. J.D., MD
wOW !!!!! What a fantastic job .., The piece never sounded better . makes my other mr-78 sound really distorted .. YOUR company really is the best I've had the experience to deal with ,THANKS for everything including the bulbs ...D.S., PA.
This is one week listening music from the MR78 : a fabulous pleasure ! We really enjoy this source of real music. Back to home we push out the stress of all the day with jazz or classical, uncompressed audio from some good radio companies in Paris. Thank you again, D.K., France
Just wanted to say how pleased I am with how things turned out on the Mac tuner and amp. Got everything hooked up and the system never sounded better. Your packaging for return shipment of the amp and tuner was super. My thanks to everyone at Audio Classics who made this happen. Hope to work with you folks again. J.D., MD
Received my wonderfully packaged and restored MR-78 (Modafferi-mod) .... and can only say WOW! I am blown away by the tuners musicality, improved stereo separation, and outstanding S/N ratio on FM stations 60 miles away that I normally listen to. On vocals it lets one hear the timbre of each voice better than before. My thanks to Mr. Modafferi for his work .....I also appreciate the nice detailed invoice of what was done. Again, thank you J.D., MD
.... I just wanted to say that the MR78 is absolutely fantastic in every way. Since I unboxed it, believe it or not we've put over 200 hours on it, running almost 24/7 in my studio, making these endless long hours bearable! Incidently, this one is the best sounding MR78 I've heard-and I've heard some damn good ones... Thanks again for the "deal"-whatever it ultimately cost me, it's worth it. Till the next transaction- B.C., CA
Just wanted to mention that the MR 78 got here on Monday. I am more than happy with the cosmetic condition of the tuner. More importantly, it sounds wonderful! Im still contemplating a CD player.... Thanks for your help. Best regards, B.M., N.J.
..my modified MR78 is nothing short of spectacular in terms of sound and soundstage. Thanks for a great job. R.F., NJ.
I recently purchased an MR78 with the modifications of Rich Modafferi, from you and I am wholly pleased with it. ... The '78 is dynamite. J.Y., OH.
The McIntosh equipment I bought from you is working great...especially the MR78 with the Modafferi modification. R.S., NY.
Received the C34V yesterday and as with the MC2002 and MR78, it is in pristine condition. Your honest representation of condition and service make your company unique in todays business world. D.I., MI.
...Thank you for the great job you did on both the MPI4 and the MR78. The MPI4 functions as it should. In fact it works better than when it was new...Thank you for your prompt courteous attention. M.P., FL.
I sent my MR78 for the full "Moda-Mod". To say that I am happy or satisfied with your work is an understatement! ... this MR78 now outperforms, in any specification or subjective criteria you wish, a number of 1990 state-of-the art tuners as well as a fully restored 10B. The quality of workmanship, packing and the fact that some of the work I requested ... was performed at minimal or no cost, make your service an excellent value. J.W., MD.
We are so pleased with the modified MR78 that the superlatives are flying all over the house. This tuner is quite simply put "Breathtaking with good signal source. R.H., FL
Re: Modafferi MR78 Modification: I've recently purchased an old MR78 and had this modification done -the result being th best tuner I have ever heard. My previous tuner -Onkyo T-9090 (I) - may be an "eye lash" better at receiving weak & distant stations; but the audio qualitiy of the mod MR78 is far superior. I have tried most of Stereophile's Class A tuners in my system, and the Mac-mod. is in a class by itself. By the way, I would rank the Magnum FT-101 best in sound quality amoung currently available tuners. J.V., TN
My MR78 Tuner is doing just fine - It was well worth the wait and I appreciated your finding such a fine instrument. J.C., NY
I'm very pleased with the results of our MR71 venture. The sound quality is truly amazing with good programming. Soft, lush top end & detailed throughout the entire range. I've never heard a tuner image like this before and it is truly exceptional in this regard. In comparison with my MR78 modified by RM, it seems to be an equal in sensitivity and general sound quality. The 78 sounds more truncated in the highs, but more extended. Also the special controls offered on the MR78 make selectivity better. I now own two of the finest sounding tuners that money can buy (yes I've heard the 10B & Sequerra) and can vigorously recommend both units to music lovers! Thanks for your advice on the RM modifications to these specimens. R.H., FL
I would like to thank Richard for developing such a great product. The MR-78 provides great overall performance, and I'm looking forward to enjoying the unit even more after Richard is through with it.J.L., MI.
I just wanted to say \"thanks\" for the L-52 cabinet I recently ordered. It arrived the other day, perfectly packed, and in the Original shipping carton! It was in mint condition; I almost felt like I had bought a brand new cabinet. My MR-78 looks great in it! J.H.,CA
Re McIntosh MR78 repair: It arrived Friday and I have been listening to it all weekend. I think it actually sounds better than when new...R.B., WA.
