The ability to connect the listener to the music makes this tube-solid state integrated a special component by any standard. I could happily listen to the MA for a long, long time. An all analog design, it comes with 2 unbalanced, 1 balanced and 1 Moving Magnet phono input for turntables. All 4 inputs can be given user-friendly names in order to simplify user control. Bass and treble tone controls help fine tune your music to your personal preferences.
A full range subwoofer output is included for use with a powered subwoofer to further enhance low frequencies. A "beautifully designed amplifier" with a "relaxing approach to the music, but still it plays with control and power. A powerful control microprocessor is used for smooth system operation, along with some of the latest audio-grade circuit components that deliver the best possible sound.
The McIntosh MA amplifier "is not only appealing to look at, it sounds great too. Far bigger than its size should indicate, and there is no reason to doubt the power, because it kicks hard.
It sonically fills 25 square meters [ square feet], does its job and disappears from the room. Power Guard monitors the output signal for signs of over driving and makes real time micro adjustments to the input signal to prevent harsh sounding clipping that could potentially damage your speakers.
If Power Guard is activated, the 2 vacuum tubes connected to the affected audio channel s will flash an amber color; they will return to their normal green color when the clipping has stopped.
And, based on McIntosh's reputation for long-term reliability and service, possibly listen for decades. It will allow you to find speakers that are the best suited to your tastes, and it will pamper them appropriately. A first-class amplifier. The expectations were big on our end and from what I heard during these listening sessions, I can, without a doubt, affirm that McIntosh succeeded the test on all points.
Input selection, bass, treble, tone bypass, balance and input offset levels can be adjusted using the front panel knobs or the included remote control; all settings and input selection will be shown on the OLED display. The entire unit sits atop a beautiful polished stainless steel chassis with a classic McIntosh-styled die cast aluminum name badge attached to each side. Hybrid design: vacuum tube preamp and solid state power amp Watts into 8 Ohms Watts into 4 Ohms 5-band tone control.

This McIntosh amplifier appreciated in value by Any McIntosh piece you buy will naturally look good in systems with other McIntosh of any age. They still use the signature black glass front panel, knobs, illuminated logo, and brushed-aluminum end caps on every piece of equipment they make. They have invented and patented technology which automatically gives any speaker the right power, prevents clipping, eliminates distortion and noise, and accurately displays power usage, just to list a few.
Stereo Barn has sold McIntosh since and we continue to sell it because it gives our customers an experience worth more than what they paid. See the full list of brands here that we sell at Stereo Barn. Stereo Barn proudly supports the Reading Symphony Orchestra.This sixth generation MC has many subtle enhancements from the previous release that greatly improve performance.
Combined with the widest bandwidth McIntosh output transformer design, the MC features tauter bass control and thermally quiet circuit design. The result is pure music. The seven small tubes are LED illuminated to indicate the amplifiers functional status: upon power up, they sequentially glow amber for a few seconds and then all turn green to signify system readiness.
In the rare case of an output tube failure, the small tubes in front of it will turn red to notify you of the problem. Power Control is used to remotely control tube illumination from a McIntosh preamplifier.

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. The music goes 'round and 'round. We all have our default settings. Every time, it's the first recording I reach for when I want to hear wussup in my system. I cued up "Return to Paradise. I thought of turning the contrast setting up or down on a television, or adjusting the amount of color saturation.
Zooming in and out also has its audio analogs. I heard a kind of fleshing out of Horn's voice, her deep mezzo gaining heft and impact.McIntosh Laboratory is an American manufacturer of handcrafted high-end audio equipment based in BinghamtonNew York.
