The McIntosh MR78 is highly regarded for superior selectivity and sensitivity with low distortion. The MR78 was designed by Richard
Modaferri and uses his patented RIMO filter, an IF passband filter with remarkable adjacent channel rejection and user selectable passbands.
Audio Classics has a limited number of these tuners that have been recently modified and aligned by the designer himself.
- Multiple selectivity, normal, narrow and super narrow, switchable from the front panel. An elegant solution to a tough problem. Switching is
done by means of diodes using DC switching; an ideal way to handle a difficult RF problem. A two position RF selectivity diode switching circuit
for low and high gain antennas adds a useful parameter that is unique.
One pair of balanced high level inputs and balanced outputs for all six outputs.
- Linear phase (constant delay) IF amplifier for low distortion at even high selectivity and low distortion. Patented two eight pole filters
are selectable as well as a four pole multi element crystal in the super narrow position.
- A phase linear bridge discriminator provides distortionless conversion from FM to audio and exhibits a capture ratio close to 0dB. No active
elements are used, providing a driftless, ideal detector.
- Five element tuning capacitor improves RF front end characteristics; more tuned circuits for better selectivity. Silver plated
chassis and RF coils for better shielding, lower losses and higher Q circuits.
- Highest spurious rejection 100dB (IHF) and highest image rejection 110dB (88 to 108 MHz). This means you receive the stations at only the
right place on the dial. You don't receive the same stations, or some mixture, as you tune across the dial.
- McIntosh developed a special detecting circuit used in the multiplex section. An advantage of this circuit is the elimination of the critical
adjustments necessary with commonly used matrixing circuits. The circuit detects the L - R sidebands, then automatically matrixes the
recovered information with the L - R carrier signal. This yields the left and right program output with maximum separation.

Feedback: The MR78 is brilliant. Although not as warm sounding as the MR67 it makes better use of the external antenna, is much more selective and the sound is crisper and more detailed. The controls give me more control over the station tuning. Plus it is a beautiful unit. G.L., NY
The MR-78 returned home yesterday ..., as predicted. It worked perfectly right away. Thank you very much for the fine work in restoring and reinvigorating my tuner. It looks better than new, and plays better than ever. It also works perfectly, and pulls in more stations though these apartment walls. Stereo lock on all local stations is 100%, a huge improvement. Again, thank you Richard Modafferi for your work. M.H., DC
Received the Mac MR78 tuner yesterday in a tank like packaging, and fired up the unit right away…The best word to describe the sound of the FM music is AMAZING, and of course paired with my first Mac C28 preamp. I think the two units are meant for each other. I placed the MR78 on top of the C28. Never thought that FM broadcast sounds like CD or better. This should be the ultimate FM tuner and will beat any sophisticated and cost to no object digital tuner in the market today. The unit is really gorgeous from any angle, well built machine, built like a tank! Thanks again for an excellent service. My next venture will be the Mac MC 150. Hope to get this one soon for my collection. R.A., FL|
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

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.
I sent my MR78 for the full
"Moda-Mod". To say that I am
happy or satisfied with your work is
... 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

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
& 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
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.
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
