MC452 Power Amp: McIntosh amplifiers have been thrilling audiophiles since 1949, when the very first model astonished the audio community by combining ample power with flat frequency response and remarkably low distortion. The MC452 is the most powerful stereo amplifier in the company’s current lineup, conservatively rated at 450 watts per channel. It features Quad Balanced circuitry that cancels nearly all distortion, and it stands apart visually thanks to larger versions of McIntosh’s signature power meter and aluminum handles. Among other enhancements, there’s a chassis updated for cooler operation, which is further assured by power transistors that employ ThermalTrak, a new technology that provides instantaneous and highly accurate transistor temperature monitoring. You also get twin-balanced input and output flexibility, along with unique binding posts that provide an optimal connection regardless of speaker cable type or termination.
MC275 Classic Tube Amplifier: Irresistibly lush sound goes a long way toward explaining why the MC275 is not only the most revered tube amplifier in the McIntosh component repertory, but very possibly the best known tube amp in high fidelity history. This truly legendary unit, with its gleaming chrome chassis and imposing KT88 power tubes, harks back to 1961, when the original version caused a tidal wave of enthusiasm in the audiophile world. Like its coveted ancestor, the current, sixth generation MC275 is a stereo amp rated at 75 watts per channel (275 stands for 2 channels x 75 watts), but its real-world power capability appreciably exceeds that conservative rating. This iteration of the MC275 includes important 21st century features and performance enhancements. Along with the widest bandwidth output transformer that McIntosh produces, you get especially taut bass control and thermally quiet circuitry. Top-quality balanced and unbalanced input connectors enhance signal transfer from your preamp while patented McIntosh gold plated binding posts assure the best connection for all speaker cables. The MC275’s seven small tubes are LED-illuminated to show the amplifier’s functional status — when you power it up, they sequentially glow amber for a few seconds then turn green to show that your system is ready. Should an output tube fail, a rare occurrence, the small tubes in front of it will glow red to alert you.
C47 Preamplifier: The C47 stereo preamp, with 12 inputs, can handle a wide variety of music sources, including many of the latest high resolution digital file formats, DSD among them. For analog audio, it includes two balanced and three unbalanced fully-assignable inputs, plus moving coil and moving magnet phono inputs. The unit’s array of digital inputs comprises two optical, one coaxial, and one USB. Its optical and coax inputs will decode digital music at up to 24-bit/192kHz for high-res playback, and it can also decode and play hi-fi DSD files via its USB input, which accepts signals up to 32-bit/384kHz and supports DSD64, DSD128, and DSD256 along with DXD 352.8kHz and DXD 384kHz. When playing SACDs, you can mate the C47 with a McIntosh MCT450 SACD/CD Transport via the MCT input, thus creating a secure custom DSD connection. All C47 inputs are available at all times, even if specific ones are assigned to certain devices, allowing you to configure your system as you wish. Bass and treble tone controls allow audio fine tuning while a Headphone Crossfeed Director provides three-dimensional headphone listening. Home Theater Pass Through permits seamless integration with a multi-channel home theater system. You can connect the C47 to numerous amplifiers and related components.
D150 Digital Preamplifier: For a complete digital stereo system, you need only connect the D150 to an amplifier, a pair of speakers, and a digital source. Or use it as a headphone amplifier by linking your digital sources and a set of ‘phones. This impressive preamp supports many of the newest digital audio formats while its USB input accepts up to 32-bit/384kHz signals and supports DSD64, DSD128, DXD 352.8kHz, and DXD 384kHz.

MHA100 Headphone Amplifier: A significant step forward in personal listening, the MHA100 combines a cornucopia of McIntosh advancements. One is a new iteration of the firm’s tried-and-true Autoformer: it provides three headphone impedance ranges, 8-40, 40-150, and 150-600 ohms to accommodate ‘phones ranging from ear buds to professional studio models. The unit also features a Headphone Crossfeed Director (HXD), which allows headphones to deliver multi-dimensional imaging and a sense of space that music lovers could previously attain only with speakers. With four digital inputs, this outstanding amplifier can decode digital music files at up to 32 bits/192kHz, and it also gives you two analog inputs. Downsized for placement flexibility, the MHA100 is easily-positioned, yet it will feed 50 watts of power to a pair of speakers when you choose to listen through them. (The power rating of McIntosh amps is invariably conservative.) The company’s famed Power Guard system prevents clipping, and a 5-Step Bass Boost control allows individualized low-frequency tailoring. Naturally, the MHA100’s polished stainless steel chassis is classically McIntosh, from the instantly-recognizable blue meters and glass front panel to the handsome, signature knobs and brushed aluminum end caps.
MHP1000 Headphones: Don’t be surprised when the MPH1000 reveals facets of your favorite musical selections that were previously veiled by your speakers and by other headphones. Its smooth, full bodied, non-fatiguing sound flows from drivers conceived in-house by the McIntosh design team, and its performance is enhanced by closed earcups that diminish environmental noise. For maximum comfort, McIntosh engineers opted for a lightweight design that applies minimal pressure to the ears, and earcup pads and headband alike are constructed of soft premium leather for an opulent feel. The MHP1000 comes with two detachable cables, one that’s 1 meter long and terminates in a 3.5 mm stereo connector, and a second that’s 3 meters long and has a 6.3 mm stereo connector. Both connectors were custom-designed by McIntosh, and both feature gold plating as well as shielded wiring for best sound. Owners of related McIntosh gear will appreciate the fact that the MHP1000 has been engineered to perform optimally with any of the firm’s current or legacy headphone amplifiers.
C2500 Tube Preamplifier: The C2500 combines traditional musical attributes with today’s digital audio requirements. Its tube circuity provides genuinely sumptuous sound while an extensive array of 15 inputs suits it for any source material you’ll want to hear. There are two phono inputs, one for turntables with moving magnet cartridges and one for those employing moving coil units, and five digital inputs, each of which feeds a built-in DAC that decodes at up to 32 bits/192kHz for highest resolution audio. Users can assign tone controls to individual source components as needed and can simultaneously connect as many as three stereo power amplifiers. (The C2500 provides on/off switching for two of those amps to simplify whole-house music distribution.) Home Theater Pass Through means the preamp can be integrated seamlessly with existing multi-channel A/V systems, and McIntosh’s High Drive headphone amplifier is incorporated for personal listening. All these benefits are packaged in a signature McIntosh chassis that isolates the unit’s analog audio circuitry with protective shielding and keeps musical signals noise-free. A top-mounted glass window lets you bask in the glow of the C2500’s six dual triode tubes.
MA5200 Integrated Amp: Integrated amps have countless fans in the high fidelity community because they combine preamp and amp on a single chassis, thereby saving buyers both money and space. We heartily recommend the MA5200, McIntosh’s entry-level integrated amplifier, which is rated at 100 watts-per-channel into 8 ohm loads. (Since McIntosh rates its amps very conservatively after rigorous testing, you can bet it delivers more power than other, similarly-rated amps.) The MA5200 also employs the firm’s exclusive Power Guard, a waveform comparison circuit that continuously monitors both input and output signals, dynamically adjusting them when necessary to avoid clipping. The unit also features the McIntosh Digital Engine, which can decode your digital music at up to 32 bits/192kHz for sound quality every bit the equal of analog, as well as the firm’s built-in High Drive headphone amplifier.

MCD550 CD/SACD Player: When you audition the MCD550 with a familiar CD, you’re bound to be surprised by musical nuances you hadn’t previously heard. In part, this can be credited to the unit’s 8-channel, 32-bit, 192kHz PCM/DSD DAC, a digital-to-analog converter with wide dynamic range and exceptionally low distortion. The MCD550 employs the converter in quad balanced mode, utilizing four DAC channels for each audio channel, to reproduce music at all levels with precision and elegance. As well as decoding PCM signals from CDs and its own digital inputs, it can handle DSD signals from SACDs. To insure superior error correction and tracking, the unit reads your discs at high speed and stores their data in a buffer memory. This outstanding player also provides both fixed and variable balanced and unbalanced outputs for maximum flexibility when connected to your system — the variable outputs allow direct connection to an amplifier without a separate preamp. You also get three digital inputs: coaxial; optical; and a USB input that allows you to stream stored digital music files with resolution up to 24bits/192kHz. Coaxial and optical outputs let you direct audio signals to a preamplifier or home theater processor. The 550 also features McIntosh’s High Drive headphone amp, which is optimized for just about every headphone you’ll ever own. A classic black glass faceplate and a rear panel with gold plated, corrosion resistant connectors complement the unit’s internal merits.
C1100 Dual-Chassis Vacuum Tube Preamplifier & Controller: The C1100 borders on the absolute. So does its silence, thanks to high-level inputs with a noise level lower than that of any other preamplifier McIntosh has ever built. The C1100’s two-chassis design completely separates the preamp’s control and power sections from its audio section, achieving total isolation of the principal preamplifier functions (control and sound) — the result is astoundingly pure music reproduction. For ultimate stereo separation and sonic purity, the C1100’s Controller and its matching Vacuum Tube Preamplifier isolate left and right channels from one another, both electrically and mechanically, and the units are connected via specially designed, high performance umbilical cables that are shielded from outside noise. Once connected, the two units act as one and are easily operated via remote control or with front panel controls. All power control, data ports and external control connections are located in the Controller section, which includes a dual microprocessor to enhance its robust nature. The Preamp section houses all audio connections and circuitry, and it gives you a total of 12 analog inputs, six balanced and four unbalanced, plus adjustable-loading moving magnet and moving coil phono inputs. Two sets of balanced outputs and two sets of unbalanced connections provide flexibility. Twelve vacuum tubes (six each of 12AX7a and 12AT7) power the preamp. For personal listening, the headphone jack has higher output than any other McIntosh preamplifier, while a Headphone Crossfeed Director (HXD) gives music heard through headphones exceptional dimensionality. Home Theater Pass Through allows for seamless integration with an existing multi-channel theater system. As is only fitting, the C1100 makes an emphatic visual statement with McIntosh black glass front panels on both enclosures, fabled blue meters, signature knobs, and illuminated logos, all of which complement the preamp’s stainless steel chassis and custom-machined brushed aluminum end caps.
C52 Preamplifier: The two-channel C52 is the most advanced, single-chassis solid state preamplifier McIntosh has ever made, packed with features and compatible with virtually any high end analog components and digital music sources you may own. For connecting analog devices, it includes three balanced and four unbalanced fully-assignable inputs, plus moving coil and moving magnet phono inputs. For digital, it includes three optical and two coaxial inputs, plus one for USB. The optical and coaxial inputs will decode digital files up to 24-bit/192kHz for high resolution audio playback. The C52 is also capable of decoding and playing DSD files, and the USB input accepts PCM signals up to 32-bit/384kHz while supporting DSD64, DSD128 and DSD256 plus DXD 352.8kHz and DXD 384kHz. The C52 also features a 24-bit/192kHz, DSD digital-to-analog-converter. All inputs are available at all times, even if you assign certain inputs to certain devices, so you have the freedom to configure your system your way. Moreover, the unit’s updated outputs are designed so that highs and/or lows are not inadvertently turned off when bi-amping or tri-amping. An 8-band analog equalizer provides all the fine-tuning capability you’ll ever want while the C52’s Headphone Crossfeed Director adds three-dimensionality to all music played through ‘phones. The unit’s passthrough capability gives you seamless integration when you use it in a multi-channel home theater. Classic McIntosh enclosure features, which include signature blue meters, match perfectly with those of sibling components from the eminent firm.
C22 2-Channel Tube Preamp: The retro design of the C22 has in no way kept McIntosh from making this stylish tube preamp the equal of any component in its current lineup. Electromagnetic input switching provides reliable, noiseless, distortion-free operation (low distortion levels of all types are less than 0.08%) so that every musical sound you hear is as accurate as it is transparent. The C22 has 10 inputs, including two balanced and six unbalanced. Its moving coil and moving magnet phono input sections feature selectable resistance and capacitive loading; that means every phono cartridge and turntable can be perfectly matched for optimum sonics. Along with a set of balanced connections and three sets of unbalanced ones, you get bass and treble tone controls that you can bypass if you wish. Power control outputs let you turn a complete McIntosh system on or off from the unit’s front panel or via remote control. Notwithstanding its retro look, the C22 has the McIntosh design cues everyone recognizes — a partial black glass front panel, signature knobs, and sturdy brushed aluminum end caps — so that it matches sibling components from the firm.
MC75 Mono Tube Amplifier: Let’s say you want an outstanding mono tube amp without opting for — or paying for — more than 75 watts. Well, the MC75 is just the ticket. (McIntosh’s power rating, by the way, is very conservative.) The unit combines classic design with state-of-the-art performance, and it provides all the features today’s music enthusiasts want and enjoy. Because the MC75 powers just a single channel, pairing two of them in a system gives you ultimate stereo separation. Moreover, the firm’s patented Unity Coupled Circuit keeps distortion low while extending frequency response and lengthening the life span of the unit’s tubes. There’s an oversized power transformer that allows a single pair of KT88 output tubes to deliver unusually high power and dynamic response, and a Sentry Monitor tube protection circuit as well. Balanced and unbalanced inputs, combined with power control, suit the MC75 for use with all contemporary McIntosh preamps and processors.
MAC6700 FM/AM/HD Receiver: Company founder Frank McIntosh was a radio engineer, so it seems only fitting that, after 20 years without a receiver, the firm’s line now includes the world’s finest. As well as providing superior FM reception when tuned to traditional stations, the unit includes HD radio technology for sound approaching CD quality from stations that broadcast hybrid digital signals. This superlative receiver will deliver performance matching that of McIntosh standalone tuners while allowing you to preset up to 20 stations on each radio band. It even includes a remote AM antenna. A 200 watt-per-channel stereo amplifier section gives the MAC6700 all the muscle you’ll ever need — it’s capable of driving just about any speaker. The McIntosh Autoformer means you get all 200 watts regardless of your speakers’ impedance, and the firm’s famed Power Guard circuit, which prevents potentially dangerous clipping, will keep those speakers safe from harm. The MAC6700’s preamp section features 11 inputs, including three digital inputs that feed a built-in DAC capable of high resolution decoding up to 32 bits/192kHz. Two dedicated phono sections are provided, one for turntables with moving magnet cartridges, and the other for moving coil, while Home Theater Pass Through lets you link the MAC6700 with a multi-channel A/V system. A McIntosh High Drive headphone amplifier with increased gain and output power is built in and optimized for virtually all headphone types.
MA7900 Integrated Amplifier: The MA7900 integrated amp packs many essentials into a single enclosure: a fine sounding preamp section; a powerful amplifier section conservatively rated at 200 watts per channel; an inboard D/A converter for handling digital music files; and two phono sections. Better yet, each of these is McIntosh-grade, so you know they’ll yield the best possible performance with program sources ranging from vinyl to digital music files. The MA7900 gives you a grand total of 12 inputs, including three that are dedicated to digital and allow high resolution decoding up to 32 bits/92kHz.

MC2301 Tube Monoblock Power Amplifier: The MC2301 is an audiophile’s dream come true. For one thing, it incorporates a contemporary version of Frank McIntosh’s legendary Unity Coupled circuit, which nearly seven decades ago lifted the first McIntosh amp head and shoulders above all others on the market. Thanks to refinement after refinement, Unity Coupling continues to endow the firm’s amplifiers with benchmark performance — in power bandwidth, flat frequency response, and low distortion alike. The MC2301 also employs Quad-Differential circuitry, a McIntosh innovation never before combined with tubes, to cancel nearly all induced noise and circuit-borne non-linearities for astoundingly low noise levels. Whether handling huge orchestral and choral forces or a rock band’s full-on assault, the MC2301 effortlessly delivers the most lifelike, most dynamic tube amplifier performance you’ve yet heard.
MXA70 Mini System: The MXA70 ups the ante for audio systems compact enough to fit tidily into offices, bedrooms or vacation homes. England’s What Hi Fi magazine called it a “classy system” that serves up “a large dose of McIntosh in a compact package” while its reliable British counterpart, Hi-Fi Choice, said it exhibits “a smoothness and a refinement you wouldn’t expect from a mini system.” This formidable ensemble mates a compact stereo amplifier, built for a lifetime of service and conservatively rated at 50 watts per channel, with a pair of two-way speakers that sound much larger than their size. For flexibility when connecting music sources, the amp has six inputs, four of which are digital and feed an internal McIntosh Digital Engine that decodes music with resolution up to 32 bits/192kHz. A dedicated headphone amp, also built in, elicits optimal performance from any ‘phone you might connect while McIntosh’s Headphone Crossfeed Director gives ‘phones imaging capability akin to that of fine loudspeakers. When driving either headphones or speakers, the vaunted McIntosh Power Guard system prevents clipping that could damage them. There’s even a built-in 5-step Bass Boost Control that allows you to customize the low end of the musical spectrum to suit your environment and your taste. On the outside, the MXA70 amplifier boasts elements that have made the McIntosh look both enduring and instantly recognizable: a polished stainless steel housing; prominent blue power meters; a glass front panel; and brushed aluminum knobs and end caps. The mini system’s high gloss, piano black speakers add to its visual impact.
MC152 Amplifier: Yes, you can save money and still own a vaunted amp from the current McIntosh lineup.

Even with its space-saving, six-inch-high chassis, the unit provides standard-setting performance, which makes the MC152 the perfect choice for music systems that don’t require higher power, or for pairing with home-theater surround speakers. This fine amp delivers 150 watts of power into two channels at 2, 4 or 8 ohms (the power rating is conservative, as is always the case with McIntosh amplifiers), and both balanced and unbalanced inputs are built in for connecting your preamp. McIntosh output Autoformers mean every speaker receives full power regardless of impedance while the firm’s unique Power Guard circuit prevents clipping that could damage speakers. Patented binding posts provide secure cable connections for optimum speaker performance. As for appearance, two large blue watt meters, a gleaming black glass front panel, and silver end caps visually telegraph the McIntosh message: high performance for a lifetime.
MC301 Monoblock Power Amplifier: McIntosh’s MC301 monoblocks are ideal for those who want monophonic amps but don’t need all the muscle of the firm’s larger units. (Because each speaker has its own dedicated amplifier, mono amps provide ultimate channel separation.) Each MC301 delivers 300 watts of conservatively-rated power to a single channel at 2, 4 or 8 ohms. Both balanced and unbalanced inputs are included for preamp connection, along with balanced and unbalanced outputs that make bi-amping speakers easy. This is a small-format McIntosh amplifier, with a space-saving chassis just 6” tall, yet it’s packed with the company’s technological advancements.

As for its looks, the MCT450 housing is classic McIntosh, from its polished stainless steel chassis to its black glass front panel and brushed aluminum end caps.
MC205 5-Channel Amplifier: This McIntosh powerhouse can deliver more than a thousand watts in total, but there’s a lot more to it than muscle. Consider its versatility: you can employ it as the sole amp in a 5.1-channel home theater, or as a dual zone amplifier. In the latter mode, it will direct three channels of power to a theater in one location (thereby adapting an existing two-channel amp for theater use) while powering a superb-sounding stereo music system in another. A further benefit is the constellation of technologies that McIntosh employs in its Dynamic Power Manager, which insures optimum performance with both 8 and 4 ohm loudspeakers — every last one of the unit’s 200 watts per channel will be fed to them. Moreover, you can listen to the MC205 for hours without being overcome by listening fatigue, an annoying phenomenon that many amplifiers cause. The unit keeps total harmonic distortion below 0.005% across the 20-20,000 Hz audio band, even at full power, and it suppresses noise. Formidable build quality also helps this brawny amplifier perform noiselessly, since it eliminates the need for the cooling fans that mask musical and cinema-sound clarity in so many other amps.
