McIntosh MC252 Power Amplifier 
Page 2

The most popular song in Depeche Mode’s entire career, “Personal Jesus” pounded out from the Aerial Acoustics loudspeakers next with a precision and clarity that I had never heard before when listening to this synth-driven power song. Gore’s vocals popped with a cadence and vocal structure that was sent out to the speakers with exceptional gritty fervor. If there were any “hiccups” in the sound engineering of this song, the Aerial Acoustics would have highlighted them with clarity, but I could not discern any minor or major lapses in sonic displacement in the song “Personal Jesus.” A true test for any power amplifier worth its salt is to experiment with sound placement by moving around the room that you are in and seeing if the audio follows you or if it only has one truly “sweet spot” that cannot be easily reproduced. I did just that during this song, and the sound not only followed me to the right corner of the room, it actually sounded more fully solid there than where I was sitting for the last ten minutes of the audio demonstration, another solid sign that the MC252 could deliver power where it’s needed the most, in the entire soundstage of the listening room, not just one or two spots.

To experience the full depth of the MC252’s power, and to witness just how the entire audio system I was listening to would handle a variation of jazz vocals, deep acoustic bass tones and piano, I loaded up Diana Krall’s 1999 release on Impulse! Records entitled “When I Look into Your Eyes.”  I skipped to a bouncy jazz number entitled “Popsicle Toes.”  This was an excellent song to sample as it highlighted the pure warmth of the MC252, along with the mid-range nuances that the Aerial Acoustics loudspeakers brought into the audio experience. The acoustic bass melody really sprang to life during this song, and you could actually hear the bass player’s fingers snapping against the taut bass strings as the piano player began adding his flourishes to the snappy tune. The main elements that distinguish the MC252 power amplifiers from other power amps in the same price range, is the ability the MC252 has in delivering a much more “natural” sound to music CD’s such as Diana Krall’s 1999 album, as well as bringing the high end of her vocals to new sonic heights without any sound blur or coarse harmonics. The next song up was a very laid-back and slow building tune called “I’ve Got You Under My Skin.” I was able to discern how this audio system sounded during the quietist parts of this song and how the MC252 amplifier would convey the emptiness of sound when there was a break in the vocals. The amplifier did a stellar job of eliminating any kind of noise at all during the silent parts, and delivered the perfect touch when it came to allowing the orchestration of this quiet piece to overwhelm the song when needed, but with a laid-back kind of smoothness that was never crude sounding.  

Downside

While the MC252 brought a natural kind of warm sound to the audio system, it also delivers a bright kind of clarity to the audio configuration that might prove too overwhelming to an audio system that’s not set up with loudspeakers that can handle the range delivered to the speaker’s tweeters.  Even though the MC252 did a good job at sending quality mid range and treble tones to the loudspeakers, the bass was just a tad too light for my tastes. Your subwoofer that is currently integrated into your own audio system should be the right match for this power amplifier, otherwise you might be disappointed by the less than stellar low end that the MC252 powers out.

Another negative aspect of this power amplifier is its sheer size and weight. At 95 pounds and standing at ten inches tall and 15 inches wide, your audio rack must be customized to handle such a formidable unit and you really need to use the most reliable and expensive cable wire to get the most clean and concise power from the MC252..

Conclusion

Suffice it to say that the McIntosh MC252 Two-Channel power amplifier does not disappoint when it comes to supplying the exact amount of power needed to drive any high-end audio system on the market today. The amp’s ability to reproduce the full audio spectrum when it comes to intricate musical displays of jazz vocals or the much more electronically-inclined music of synth bands from the 1980’s, you cannot really go wrong by purchasing one of these amplifiers for your own sound system. The engineers at McIntosh have outdone themselves by implementing several new selling points in the design of the MC252, including the exclusive power guard system which protects your loudspeakers and audio system by adjusting the input level at all times, which prevents clipping and sudden drops in sound clarity.

You must have a really good idea if your system at home would be a perfect match for the MC252 before purchasing one. This amplifier has a substantial ability to drive mid-range sounds to any pair of loudspeakers that need it, but since the low-end suffers a bit, I would highly recommend that your audio system features a very fatty subwoofer so that you can still get the low-end signals that you really need, while at the same time you are upgrading your high-end so much that even the old music CD’s you have in your vast musical collection sounds as fresh as the day you bought them. And if you are a genuine fan of the McIntosh label, you will not be disappointed in purchasing at least one of the MC252’s for your system.

Enjoyed your article about theMcIntosh MC252. You however stated that Mac made
amps in 1990. McIntosh is one of the last American audio companies made in the
USA, and their beginnings go back to the late 1940's (or thereabouts). Their
comitment is renouned. A case in point my first peice of Mac equipment, C-26
Pre-amp, MR77 FM tuner, and 2105 Power amp were all purchase in 1969.


Expensive yes, performance unsurpassed. Only in 2008 did I sell my tuner,
and pre-amp and power amp in order to upgrade to home thearter equpiment. After
all these years upon selling the equipment I got what I paid for it when
new.

Cordially,
Kenny Klem

Bonjour à tous,

j'ai fait l'acquisition récente, du MC252, qui alimentent une
paire d'enceintes françaises CABASSE COLONNES 135.
Ces enceintes ont un haut
rendement: 93db/w/m
Le son est d'un naturel saisissant !! on ne sait pas si ce
sont les enceintes qui jouent ou l'instrument.
Les basses sont pour ma part tout
à fait satisfaisantes
j'ai essayé le MC402, et j'y ai trouvé peu de
différence

My MX110 tuner/preamp was made in 1962. I've had it for nearly thirty years
myself. It's the one piece in my system I've never had the urge to change. Had
Richard Modafferi work on it a couple of years ago, and sounds better than
ever!
Hope to pair it with an MC252 in the near future.

Bonjour,
J'ai eu l'occasion d'essayer, les deux amplis MC252 et MC402.
sur des
enceintes à haut rendement, 93dB/w/m, il y a peu de différence entre les deux
appareils, le MC252 gardant l'avantage d'être moins lourd et moins
volumineux.
Sur des enceintes à 82 dB/W/m, de même que sur les enceintes 2 ou 4
ohms, le MC402 est plus " à l'aise" surtout dans les graves
Sur les
médium-aigus, pas de différence.
Un petit détail: je crois que sur tous les
macintosh, il y a ce même problème curieux ?? il y a un peu de jeu dans les
boutons.Pourquoi ?? pour un appareil de haut de gamme tout de même!!!
Enfin j'ai
comparé l'ampli mac 252 à un ampli harman citation 22, les différences sont les
suivantes:
le harman est un peu plus dynamique,mais aussi plus agressif dans
l'aigu
Le mac est plus doux dans l'aigu, et de plus les basses sont plus
présentes à bas niveau ...
Enfin j'ai choisi l'ampli macintosh 252, pour les
tranfos de sortie ++++ car c'est une protection absolue pour mes enceintes, vis
à vis du DC current
Dommage que l'on ne parle pas assez souvent de cet ampli
dans la presse, même dans " the absolute sound" auquel je suis abonné et
que je reçois en France
Amitiées à tous les amateurs de produit sûrs et
solides.

Arthur  - A few comments about this review   |2010-05-20 04:55:27
McIntosh has been making amplifiers since 1949.

The first multi-channel
amplifier they made was the MC7106, which came out in 1992.

The price of the
MC252 is currently $5,000.

All McIntosh amps from the last two decades have
Sentry Monitor and Power Guard - not just this model.

Speakers only offer
subtlety and dynamics if the amplifier and source are able to convey it to them.
In a review using a system that is not one's own, traits cannot be reliably
attributed to one component or an other. It takes lots of time and
experimentation in a familiar setting to determine what an individual component
sounds like.

In addition, I want to point out that expectations for A/V and for
audiophile playback are quite different. "Very fatty" bass is
considered horrible by audiophiles but loved by the AV crowd.

Also, it is
clear the reviewer is used to hearing a subwoofer. The problem is not the lack
of bass from the amp but rather the lack of depth from the speakers. 4x7"
woofers in a 15x17 room is plenty of bass, especially with a Mc, but bass
extension of the Aerials is nothing like a subwoofer or amp can do - hence the
"problem." The amp's response is down only 3dB at 10Hz so clearly,
light bass cannot be attributed to the amp. I have heard the MC252 sound
absolutely thunderous on huge Focal Utopia speakers.

The prior author in this string of comments points to the importance of
listening to new equipment with your own system. It is not possible to know
which of several unfamiliar components is responsible for observed sound
characteristics. Find a local dealer and add the McIntosh mc 252 to your
existing system and see what it does.

As to Aerial Acoustics speakers lacking
bass, I would disagree. I have owned Model 8B's (no longer made) for over 10
years, and use an Ayre CX-7eMP CD player, Ayre K-5xeMP pre-amp and Proceed HPA2
amp rated at 250w/channel at 8 ohms. No shortage of bass. I suggest the
reviewer consider what effect, if any, the speaker placement in the listening
room may have. And the prior commenter was right on target in stating that
those who use sub-woofers in an AV system tend to be looking for room-rocking
bass that is unnatural in classical, jazz and other acoustic music
performances. I have a large M&K sub-woofer, but it is not used for 2-channel
music listening - only for multi-channel home theater.

Magazine and similar
reviews are not very helpful unless the writer is comparing one piece of new
equipment to other things in the system that he/she listens to every day.
