It is perhaps the finest, most sophisticated amplifier I have heard in its price range in my system. While still looking very much like a McIntosh, the MC has received some key design updates. Direct LED backlighting now illuminates the front panel for improved color accuracy.

The audio output Autoformers still straddle the power transformer, but are now located in new enclosures that are capped by a single cover containing glass inserts that show the wiring diagram for each transformer.

Numerous circuit components and internal wiring have also been upgraded. The MC sits on a beautiful polished stainless steel chassis and features the timeless McIntosh black glass front panel, illuminated logo, control knobs, aluminum end caps and a pair of fast responding blue Watt meters.

After spending seven years in Silver Springs Maryland they moved to a newly built facility in Binghamton, New York where they remain to this very day.

Let it be known that I am no stranger to McIntosh Audio gear. Various McIntosh products throughout the years have entered and unfortunately left this humble abode yet there are still two pieces with me today. Guests are amazed when shown my original McIntosh MC tube power amplifier they were built from and a near museum quality tube MR FM tuner with the optional slant leg wooden cabinet produced from Of course they do and it is always my pleasure to let people experience just how good they still sound.

The high prices McIntosh products bring on the used market are a direct reflection of their ability to last throughout the years. Quality and reliability are two words synonymous with McIntosh audio equipment. McIntosh Labs still produces many high quality products with designs that are eye candy for audiophiles and with sonic capabilities to match. It would take too long to go into all the various legendary products McIntosh has sold throughout the years or are currently offering today.

Gee did I forget to mention they also design a belt-driven turntable complete with tone -arm and cartridge. As you can see an entire system from beginning to end could be purchased with just one visit to your local McIntosh dealer. Spend some time reading over product details on their web-site then head on down to your local dealer and treat yourself to a day of fun and excitement as you experience these products first hand.

It weighs in at pounds sans shipping carton and pounds with. Therefore it is best to have a strong friend or two to help carry it into your house for placement within your audio system. Luckily my twenty-one year old son was there to assist me in lifting it on top of my audio rack. This amplifier was definitely meant to be displayed with its beautiful front faceplate featuring two large easy to read watt meters and two equally attractive aluminum side handles.

Two small LED lights located in-between these meters tell when the Power Guard circuit is activated for either or both channels more on that later. Of course there is also an IEC outlet to the delight of those with high performance power cables. It would seem that the designers at McIntosh Labs rightly assumed most owners would want their MC openly displayed front and rear rather than left behind closed audio cabinet doors.

Located directly behind that beautiful front panel are two Autoformers and in between them one very large thirty pound output transformer. You also have ample cooling fins which McIntosh lists at being more than square inches worth. These fins are to help keep your from overheating without using large fans and that familiar accompanying fan noise found on some amplifiers. Close by and hidden from view are four rather large main filter capacitors rated for storing over Joules of energy.

As for internal designs this one has plenty. Each half of the amplifier contains complimentary balanced circuitry. The resulting Quad Balanced configuration cancels even order distortion. Its Sentry Monitor system is a short-circuit protection device, no fuses needed, to disengage the output stage before damage can be done. This system continually monitors both voltage and current at the output stage keeping it within safe limits and will afterward automatically resets itself.

Enough of this though for all we really need to know is how does it sound? So let us move forward now and experience all the MC has to offer in a real world environment. These loudspeakers are great at revealing the voice of any associated equipment that has been my privilege to put in front of them, whether CD players, turntables, cables, preamplifiers or amplifiers.

It is my pleasure to inform you the answer is both yes and no. Yes in that it sounded clear and holographic with good detail but no in that it had a more solid lower bass foundation enhanced by all that extra power factory stated at watts minimum. As for dynamics the life of music in a word YES! The snapping of fingers in the beginning had a realistic quality about it as did all vocals. Never did music feel restrained but rather open and forceful with plenty of power behind each note.

The feeling that you could tap into an almost limitless supply of clean clear musical energy prevailed throughout this review tempting me to turn up the volume more than was normal for my listening pleasure.A one-of-a-kind, ultimate solution for bi-amping loudspeakers: a Watt vacuum tube amplifier and a Watt solid state amplifier on one chassis.

The MC is replacing the MC Stereo Power Amplifier which has been around in its current guise since and has had its innards girded to the tune of a nearly 50 per cent boost in filter capacity yielding a 66 per cent increase in dynamic headroom from 1.

The MC features both balanced and unbalanced outputs making bi-amping and tri-amping easier, or for feeding a second system or — there's more — home theatre people should smile connect a subwoofer.

Chain of playback is what it's about Submitted by Rafe Arnott on July 17, - pm. Hi, If you like to listen to computer audio through a two-channel or multi-channel setup, you'll need an amplifier to hook up your speakers to. Unless you just like to plug in your headphones into your Android, or iDevice or your computer and forego the whole stereo thing I'm a bit more into the whole holistic playback chain that makes computer audio compete, or beat traditional analog playback chains Turntable, reel-to-reel, cassette, CD — what have you, that are then connected to preamps, amps, speakers, etc.

You get where I'm going.A patent was granted that same year for the Unity Coupled circuit and transformer. A week after the MC's arrival I saw for myself, on a guided tour of the plant, how it all comes together. What are you? The solid-state MC power amplifier replaces the MC and is now the most powerful stereo amplifier McIntosh offers, with a specified continuous power output of Wpc into 2, 4, or 8 ohms, and peak output current of 75 amperes per channel.

The MC's distortion is specified as not exceeding 0. In the MC, which operates in class-AB, the concept of complementary pairs is taken to an extreme. What McIntosh has created is a push-pull amp in which each phase of the signal waveform is itself amplified by a push-pull output section: There are two complete push-pull amplifiers in each channel, their outputs combined in what McIntosh refers to as a Quad Balanced architecture.

Beginning in with their first transistor amp, the MC, McIntosh has used output-stage Autoformers to optimize impedance matching between output devices and loudspeaker loads, as well as to protect the latter from DC. Fifty-two years later, an output-stage Autoformer allows the company to combine the outputs of multiple push-pull amps in a manner that, they say, has unprecedented distortion-cancelling capabilities. This is also how the MC can deliver the same Wpc output to its pairs of 2, 4, or 8 ohm speaker taps.

This cool running is in part achieved through what McIntosh describes as their current-generation ThermalTrak Power Transistors; the MC's power output circuit monitors their temperature and adjusts bias accordingly. Another reason is the extensive, heavy-duty heatsinking built into the rear half of the MC Also visible from that vantage is evidence of McIntosh's pride in the MC's lineage: circuit block diagrams handsomely adorn the top plate.

At The black glass faceplate proudly displays two large meters backlit in McIntosh blue, each about 5. The meters' upper scale is calibrated in watts, to indicate the MC's output: the large numbers top out atand after that, in smaller numbers, come "" and "1. The rest of the front panel is minimalist. There are only two control knobs: the one at left, labeled Meter, turns the meters' Lights Off if desired; the Watts setting shows you real-time meter readings, while Hold lets the needles linger on peak output levels before slowly resuming action.

The rear end of the MC is straightforward. In addition to the six pairs of speaker output taps sticking straight up from the shallow rear deck are AC in, a fuse bay, and, jutting out horizontally from the rear panel, pairs of balanced and unbalanced inputs and outputs.

One small switch lets you select between balanced and unbalanced operation, and with another you can enable or disable the Auto Off function, which shuts down the MC after it hasn't sensed an input signal for 30 minutes. I particularly liked McIntosh's patented gold-plated speaker binding posts. Each has two moving parts, which you first tighten with your fingers, then tighten a further quarter-turn with a small wrench suppliedfor a snug connection.

System and setup Not wanting to face too many variables, and to give the MC enough time to break in, I spent my first days with my system unchanged, listening to my Harbeth Central upstate New York, where I live, benefits from ample clean power, but kicking that power's quality up a big notch is my AudioQuest Niagara power-line conditioner.

The two amplifiers in my reference system that had preceded the MC, a solid-state and a single-ended tube design, each produced some level of hum, as well as noise through my speakers, that I could never eliminate.
