Pure PowerThe M23 employs Eigentakt™ class-D amplifier modules manufactured by NAD under license from Denmark’s Purifi Audio. Purifi’s load-invariant design provides wide, flat frequency response, even into challenging loudspeaker loads. Noise, harmonic distortion, and IM distortion are virtually unmeasurable at all frequencies and output levels. Another benefit of the Eigentakt™ design is extremely low output impedance and correspondingly high damping factor, for iron-clad control of the loudspeaker output. NAD combines the Eigentakt™ design with our own sophisticated switched-mode power supply, which can provide additional reserves of current when needed. Amazingly powerful and transparent, the M23 can deliver 2x260W of peak power into 8 ohms and 2x520W into 4 ohms.Uncompromised PerformanceThe ideal amplifier will achieve vanishingly low distortion, ultra-high damping factor, and rock-solid stability with any loudspeaker loud. There are many amplifiers that perform well in one or two of these areas, but fall short in others. Thanks to Purifi’s highly efficient Eigentakt™ design and NAD’s proven switch-mode power supplies, the M23 excels in all three areas – without the excess weight and cost of the old-fashioned linear power supplies and class-AB output stages used with traditional amplifiers. Eigentakt™ outperforms previous class-D implementations by a significant margin, delivering transparent, detailed sound with expansive soundstaging and holographic imaging, at all listening levels and with all types of program material – even during complex musical passages.Flexible and PowerfulEquipped with single-ended RCA and balanced XLR auto-sensing inputs, three-position gain-control switch, and 12V trigger input, the NAD Masters M23 HybridDgital Stereo Power Amplifier can easily be integrated into a high-performance separates system.

Kaluga is based on world's most sought after class-D technology: Ncore'. Unprecedented low distortion, noise and output impedance combine into what scores of enthusiastic users unanimously describe as 'no sonic signature at all'. Just music, glorious music. For instance, the two supposedly unassailable strongholds of class-A amplifiers are linearity and output impedance, at high frequencies. Plotted on next page are the output impedance as a function of frequency and the output spectrum in a high power (400W), high frequency IMD test. In both cases Kaluga outperforms any power amplifier, regardless of technology, operating class or asking price, of which such test results are available.The amplifier board is a Mola Mola specific design. The audio circuitry is trimmed to the bare bones and board-to-board connectors are eliminated in favour of soldering star-quad cables directly into the circuit board for the cleanest, lowest impedance connection possible. The input stage is implemented on a separate circuit board that uses the same discrete buffers as those found in the Makua. The output filter sports monolithic capacitors whose dielectric stability is reflected in an impressively neutral and poised rendition. The days of compromising power efficiency for audio performance are finally over: the Kaluga delivers definitive audio performance with power efficiency thrown in as a bonus.

The standalone version of our well-known archival grade Phono stage features three single-ended inputs and one balanced input. It has a balanced output as well as a single-ended output. The Lupe with its dedicated power supply, k and the added "subsonic filter" provides the discerning record aficionado with the most accurate set-up for recreating the magic of the turntable as it was intended. The display of the well-known "half sized chassis" Lupe offers at a glance information on the settings.What was conceived as a simple RIAA add-on for the Makua Preamplifier (also available in the Kula Integrated amplifier) has quickly spiraled into the quietest and probably most versatile phono stage ever built. MC/MM input stages are optimized for current noise and voltage noise respectively. Unlike the more common arrangement of an MC head amp feeding into the MM stage, the two stages are fully independent, realizing an equally short signal path for both. Input gain is switchable in 5dB steps over a 40dB range. Input resistance and capacitance are individually switchable. Available EQ settings cover practically all known cutting curves including 78 RPM.All settings are software controllable, either on the fly using a smart-phone or tablet via the Mola Mola Remote app or directly stored under the preset buttons. Digitally controlled all switching is done in the analogue domain. The Lupe can be configured to route any of the four inputs through the phono stage, this allows you to have multiple turntables and/or cartridges connected.

Experience stereo bliss with the MC462 Amplifier. The MC462 replaces the highly regarded MC452 as our most powerful stereo amplifier. Like the MC452, it features a robust output of 450 Watts per channel. With a dedicated McIntosh Autoformer™ connected to each audio channel, the full 450 Watts is available to any speaker regardless if it has 2, 4 or 8 Ohm impedance. Just one MC462 Amplifier can single-handedly power a world class home audio stereo system.The new generation MC462 stereo amplifier has received numerous updates compared to the previous model. The most prominent is that filter capacity has been increased by nearly 50%, which has resulted in a remarkable 66% increase in dynamic headroom from 1.8dB to 3.0dB. This allows the MC462 to easily handle drastic swings in dynamics and effortlessly reproduce your favorite music with virtually no distortion. Bass performance is also improved as a result of the filter capacity increase. Our eco-friendly power management system, which will turn the amplifier off after a set amount of time when no input signal has been detected, has been added. Internal wiring and select circuit components have also been upgraded.Aesthetically, the MC462 retains all the hallmarks of a McIntosh amplifier with a few key modern enhancements. The front panel now utilizes direct LED backlighting that improves appearance and color accuracy. The two audio Autoformers and single power transformer are housed in new enclosures topped by a single machined cover with glass inserts. The back half of the amplifier is home to four of our Monogrammed Heatsinks™ which connect to advanced high current output transistors that help eliminate thermal equilibrium lag time.Power Guard® that monitors and adjusts the input signal at the speed of light and makes real time adjustments to prevent harsh sounding and potentially speaker damaging clippingSentry Monitor™ - our fuse-less short-circuit protection circuit that disengages the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return to normalQuad Balanced design that cancels virtually all noise and distortion that may have crept into the audio signalPower Control to send power on/off signals to other connected McIntosh components (such as CD Players, turntables, tuners and media streamers) for easy system power up and shutdownOur patented Solid Cinch™ speaker binding posts that easily but securely attach the speaker cables to prevent them from coming loose and possibly causing a short; the binding posts are also gold-plated to prevent corrosion and ensure a quality signal is sent over your speaker cables

Give your home theater the power it deserves with the MC255 5-Channel Home Theater Power Amplifier. The MC255 features our striking new TripleView™ Power Output Meter that independently indicates the real time power reading of the amplifier’s three front channels. Instead of three separate meter windows each housing a single meter as found on our previous 5-channel home theater amplifier, the easy-to-read, 15” (38 cm) wide TripleView features three of our traditional mechanical meters in a single meter enclosure.While a totally new design, each of the three peak responding pointers in the TripleView meter have the same enticing motion that McIntosh meters are known for and function at the same high level as any of our meters. The enchanting look and welcoming glow of the TripleView meter is sure to draw interest from friends and family, but its trademarked blue lighting can be turned off so as not to compete with your TV or movie screen.Besides the new TripleView meter, the MC255 has received many other performance upgrades to deliver an unforgettable cinema experience in your home theater. Filter capacity has been increased by 50% which has more than doubled dynamic headroom from 1.7dB to 3.6dB – a key feature in a home theater amplifier – as well as improving the performance of low frequencies. When using just the front left, center and right channels, power output has been increased by 25% from 200 Watts per channel (WPC) to 250 WPC. When using all 5 channels, each will receive a healthy 200 WPC. Regardless of how many channels are used, the full 200 or 250 Watts is delivered to either 4 or 8 Ohm speakers via our Dynamic Power Manager® (DPM) technology.McIntosh Monogrammed Heatsink.The MC255 runs cool and quiet thanks to four of our McIntosh Monogrammed Heatsinks™ which are connected to advanced high current output transistors that efficiently and silently cool the amplifier; as a result, noisy cooling fans that can interfere with the movie soundtrack are not needed. A quiet, specially wound toroidal isolation power transformer also helps keep noise to a minimum. Speaker terminals have been updated to our standard gold-plated binding posts that prevent corrosion and ensure a quality signal is sent to your home theater speakers.Traditional McIntosh knobs now adorn the front panel to control the meter lights and power function. Direct LED backlighting has been added to the front panel for improved color accuracy and durability. Our eco-friendly power management system that will turn the amplifier off after a set amount of time when no input signal has been detected is also now included.While the MC255 has received many upgrades, it also comes with hallmark McIntosh technologies such as Power Guard® that prevents potential speaker damage caused by clipping and over-driving of the amplifier, and Sentry Monitor™ that protects against short-circuits by disengaging the output stage should the current ever exceed safe operating levels (it then resets automatically when operating conditions return to normal). Both balanced and unbalanced inputs are included to connect your home theater processor to the MC255 home theater amplifier.

It is well known that using monoblock amplifiers, as opposed to both channels together as a stereo chassis, is the best way to get powerful and lifelike music. By using separate power supplies that can be much more massive, each amplifier can have more dynamic power and be quieter. Keeping two separate amplifiers also makes any inter-channel crosstalk in the amplifiers impossible, so separation is better, meaning your soundstage and musical imaging will be larger and more well-defined. The simple act of separating the two channels provides a lot of distinct advantages, but also increases the investment because of needing to double up on power supplies and chassis parts.Is this extra expense worth it? One listen to the CAD-211FE will convince you that it most certainly is. With over 70 watts of class-A power, automatically transitioning as needed to over 150 watts in class-AB, this powerhouse will effortlessly drive nearly any speaker to realistic live performance levels. It includes a bias meter on the front panel to help you maintain your amplifier at its peak operating level, and offers both XLR balanced and RCA single-ended inputs to match your system. Fully differentially-balanced construction, zero global feedback, and huge reserves of current and power mean that your system will come alive with all types of music and movies.

The CAD-805 Reference Series (CAD-805RS) is the latest edition in the 805 series of single-ended mono block amplifiers that has been in continuous production since 1993.Here is what you will see with a pair of CAD-805RS moving from front to back. The front panel is a handsome thick machined aluminum that is available in either silver or black anodized finish. The CAD-805RS is equipped with a built-in meter on the front of the chassis. The adjustment pot is located at the rear of the chassis along with a bias jack for an external meter. Looking at the amplifier from above, you see a top-plate, which is finished in a handsome Anthracite Black gloss enamel, with white silkscreened lettering. To the left, the main power switch, to the right the ‘standby/operate’ switch which powers up the 211 or 845 output tubes. To the left is a rotary switch with a green jewel-like knob that chooses the appropriate bias for your choice of 211 or 845 output tubes. To the right is a similar rotary knob that dials in ‘negative feedback’ on a global basis and is adjustable from “off” in a continual rotation to a max of 10 dB of feedback. Also, on this top front portion of the amplifier are two 6SN7 input stage tubes, a 300B driver stage tube, and your choice of either an 845 or 211 output tube.Behind the tubes, the main real-estate of the 805 is occupied by two very impressively sized transformers—one power, and one output, and four electrolytic capacitors. Also, toward the rear of the chassis are the aforementioned setscrew adjustment pot for biasing purposes and the quarter inch bias jack for reading the bias of the 300B driver tube. These are the only user adjustments you will have to worry about, other than choosing your output tube flavor.The back panel offers a choice of 4, 8, or 16 ohm speaker outputs that are very high quality and heavy duty. There is a RCA input jack and a XLR input jack with a user selectable switch, and two visible fuses—one for the 300B and one for the output tube. There is also a built-in fuse within the AC power socket. The power cord is detachable.To review the circuit, the single-ended audio input signal from the outside world is passed to the control input grid of the first 6SN7 tube. This first 6SN7 stage is operating in a parallel dual triode conventional resistance-coupled Class A amplifier. This first gain stage is directly coupled to the next 6SN7 dual triode gain stage. This second stage is operating in a series anode constant-current Class A amplifier. This amplified audio signal is passed through a coupling capacitor to the grid of the 300B driver stage.The 300B triode tube operates in a Class A single-ended mode utilizing fixed negative grid voltage on the 300B driver stage. This negative grid voltage is user-adjusted by the screwdriver pot at the rear of the CAD-805RS. The 300B is directly coupled to the grid of either a 211 or 845, 100-watt plate dissipation, triode output tube. The method of coupling at this stage is called an interstage transformer. This is an air-gap design with a flat frequency response from 30Hz to 23 KHz.The audio signal from the 300B interstage transformer will drive the 211/845 output tube to 27 watts Class A output. With additional volume levels, the amplifier goes into a positive grid mode with a power output of 50 watts Class A2. In the case of the 211-output tube, the Class A2 power is on the order of 70 watts at clipping. The high-power output from the 211/845 tube is coupled to the loudspeaker via an air-gapped 150 watt continuous duty output transformer. This transforms the high impedance (8000 ohm primary winding) of the output tube to 4,8, or 16 ohms to drive the loudspeaker.

The end result is a power amplifier that brings the original recording to life in truly spectacular fashion.Short and SweetAlthough minimal in its exterior design, Edge M has some complex audio engineering inside. To remove the barriers between you and your music, we have worked hard to minimise the number of components in the signal path. As a result, Edge M delivers a more faithful reproduction of the original recording; an impressively detailed three-dimensional sound, with striking staging and focus.More Musical DetailWe pioneered the use of toroidal transformers in amplifiers, which led to improved performance. In Edge we take this one step further, using opposing symmetry twin toroidal transformers. This cancels out electromagnetic interference whilst offering outstanding power and maintaining consistent tonality, no matter how loud it’s played.Effortless Power Without DistortionUsing standard Class A amplifier technology wasn’t going to be efficient enough for Edge M. Instead we added a bias voltage to a traditional Class AB design, reducing distortion to inaudible levels. This unique configuration also produces less heat and makes the whole system much more effective.Perfect PartnersEdge systems are designed to work in perfect synchronisation. Match a pair of Edge Ms with our most versatile Preamplifier Network Player, Edge NQ, to create a hi-fi system with a sound, and a look, unlike anything else.

Performance From The HeartIn life we admire “heart.” When we say someone has heart we mean passion, spirit, fortitude. And we applaud it. While the amplifier is the brawn behind every successful music and movie presentation, it is also the heart! Its role is as crucial as that of the speakers in its ability to render delicate musical detail one moment and deliver room-shaking explosions the next. The most exquisite piece of music falls flat without clean, quiet power to sustain it through to its natural, musical ebb. Movie special effects require an inordinate supply of stable, high current power to give visceral credibility to the “special” aspect of each effect! In fact, all truly successful sound reproduction requires “heart.” The heart of an amplifier rests with its design and it is here that P2 and P5 amplifiers reveal their high-end lineage: multi-layered, hand-designed circuit boards with thick copper traces; rugged, independent power supplies with tuned toroidal power transformers for each amplifier channel; fourteen rugged bipolar output devices per channel; custom-designed convection-cooled heatsinks with serrated fins; a “no-fuse” design strategy. And the list goes on.

Designed to match, engineered for power.New MCA multi-channel amplifiers are Crafted in Canada and perfectly match the new AVM 60 processor & MRX receivers.To complement the NEW AVM 60 A/V Processor, Anthem introduces the new MCA 525, 325 and 225 power amplifiers. Available in 5, 3 and 2-channel configurations, these new MCA amplifiers feature more robust and efficient power and heavy-duty reliability. The new MCA Series delivers lower THD (total harmonic distortion) for more clean, pure sound and lower noise for a supremely quiet background.Like all Anthem products the MCA 525, MCA 325 and MCA 225, designed and Crafted in Canada, are like no other amplifiers in the world: custom low noise high-power toroidal transformers; high-current bipolar output transistors; high-quality filter capacitors; advanced power supply regulators; oversized aluminum heatsinks; custom-designed dual binding posts; and patented auto-on/off circuitry. Superior craftsmanship that is reflected in clean, clear, audiophile-quality sound from top to bottom of the frequency spectrum.An All New MCA SeriesWhat does it take to improve on perfection? Over 15 years of concentration. The distillation of endless hours of fundamental research. The willingness to rebuild from the ground up. And the focus on a single goal: Leadership through innovation and technology. Introducing the new generation of Anthem MCA Amplifiers, designed, engineered and manufactured in Canada!Completely RedesignedThe new MCA series greatly reduces the use of internal cabling for a much smoother circuit path for pure, unobstructed audio performance. The use of low-flux toroidal transformers and improved input transistors provide a greater sense of transparency, even with dynamically complex material.We’ve also improved other performance benchmarks including power bandwidth and slew rate. With a signal-to-noise ratio of 120 dB, background noise is practically nonexistent, leaving you with just pure natural sound reproduction.Higher Power into More Demanding LoadsExperience the immense dynamics of up to 600 clean Watts delivered into demanding 2-Ohm loads. Both power supply impedance and internal cabling inductance have been minimized to deliver a clear path for maximum power – even in the most demanding conditions. While previous 5-channel MCA amps used a single power supply for front left and right channels and another power supply of the centre and surround, the new MCA 525 shares its two power supply between all channels. The result is full bursts of power – instantly – without affecting channel separation.Next generation Advanced Load Monitoring™ TechnologyExclusive ALM™ technology monitors internal temperature, current and voltage to ensure safe and uninterrupted longterm operation, all the while eliminating the need for internal fuses. ALM™ is not in the signal path, so it never gets in the way. Instead, ALM engages instantly, but only in the most extreme circumstances, to protect your amplifier (and speakers) from damage.This new generation ALM™ lowers the chance of a line fuse blowing during an over-current condition. Should a fault condition arise, unaffected channels continue to play and all-channel operation resumes automatically once conditions are back to normal. The LED on the front panel confirms status at all times.Engineered for ReliabilityThe new generation of MCA Amplifiers uses of Anthem’s years of experience to “engineer out” common amplifier gremlins. Consequently, we’ve removed output relays, so the signal path has absolutely no moving parts. All parts, including the eight bipolar output transistors per channel, are run conservatively so they remain within their safe operating range. Power-on inrush current has been minimized to reduce line disturbances and stress on internal components. We’ve also upgraded internal connectors and increased mechanical strength.Green “Standby” Power ConsumptionIn addition to the reduced inrush current, these new MCA Amplifiers only use between 1-2W in “standby” mode. As with all Anthem amplifiers, they can be switched on manually, via trigger, or by sensing an input signal. New, larger, more conductive audiophile binding posts have been added to maximize contact and maintain a firm grip on the speaker cable. If you’re in the market for cutting-edge audio component separates, Anthem’s new MCA Amplifiers balance the complex dynamics of today’s most demanding multi-channel media with the rare finesse required to satisfy the audiophile in you. MCA Amps provide an abundance of conservatively rated power into demanding low impedance loads, incredible reliability, and a new design aesthetic that matches our sleek AVM 60 Pre-Amplifier.Massive Toroidal Power SuppliesMCA amplifiers deliver incredible dynamics thanks to massive “audiophile approved” conservatively rated power supplies designed with high rail voltages. Low flux toroidal power transformers ensure ultra quiet performance by minimizing stray magnetic field radiation. This provides the pure, clean, low-noise power that is needed to reproduce the full dynamics of home theater and the most complex and dynamic music recordings.Quality ComponentsAnthem MCA amplifiers are designed, engineered, and completely Crafted in Canada. We take pride in using only the highest quality components for each one we hand-build.Audiophile Binding PostsOur own custom-designed, oversized robust binding posts ensure full power delivery at all times. They’re easy to use and facilitate large speaker cable connectors.Stable as a RockOur amplifiers are incredibly stable into difficult, low-impedance speaker loads, making these superb-sounding dynamos reliable performers in even the toughest circumstances.

1-Channel Solid State Amplifier : 1,200 Watt Quad Balanced Monoblock, Redesigned from top to bottomThe MC1.25KW Quad Balanced Power Amplifier is one of our most advanced amplifiers. Redesigned from top to bottom, it replaces the venerable MC1.2KW as our most powerful single chassis monoblock amplifier. A simple glance at this 158 pound (71.7 kg) amp is enough to convey its power and performance capabilities, but when you hear it – then you’ll truly understand what it can do.The MC1.25KW outputs 1,200 Watts of pure power into a single channel with a nearly imperceptible total harmonic distortion of 0.005%. This astonishing amount of power is fully available to 2, 4 or 8 Ohm speakers our Autoformer™ technology. A pair of these amps can anchor a home audio system that can rival nearly any stereo system in the world.Updates and enhancements abound in the MC1.25KW. A 50% increase in filter capacity improves the performance of low end frequencies as well as increasing dynamic headroom. The top of the amp showcases an updated yet unmistakable McIntosh industrial design that will fit right in with current McIntosh products or those made decades ago. The audio Autoformer and power transformer remain located just behind the front panel but are now contained in new glass topped enclosures. In between them is new circular glasswork housing the amplifier’s name badge that is adorned with a decorative trim ring.The rear of the unit features 4 of our McIntosh Monogrammed Heatsinks™. Made from high quality materials with excellent thermal conductivity properties, these heatsinks are so efficient at dissipating heat that they warrant bearing the McIntosh “Mc” logo. They connect to advanced high current output transistors that eliminate thermal equilibrium lag time so that the first musical note played sounds just as good as songs played later in your listening session. The heatsinks are capped with handsome ventilation trim plates. These trim plates and the circular trim ring are made from aluminum and are finished to match the front panel handles.The AC receptacle has been repositioned to provide additional clearance so a wider assortment of power cords can more easily be used. All of this sits atop a polished stainless steel chassis which rests on 4 new redesigned feet that feature a chamfered edge. Other updates include an updated power transformer, heavier gauge internal wiring, upgraded circuit components, and the addition of our power management system that will turn the amp off after a set amount of time when no input signal has been detected.With all the changes and improvements made in the MC1.25KW, one thing that hasn’t changed is the large, fast responding 11” (27.9 cm) blue Watt meter that accurately shows the amp’s power output. Also unchanged is the signature black glass front panel with control knobs, illuminated logo, and aluminum end caps with handles. The front panel and meter have new direct LED backlighting for improved appearance and color accuracy.Other exclusive McIntosh features included in the MC1.25KW include:Power Guard® that monitors and adjusts the output signal at the speed of light and makes real time adjustments to prevent harsh sounding and potentially speaker damaging clippingSentry Monitor™ - our fuse-less short-circuit protection circuit that disengages the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return to normalQuad Balanced design that cancels virtually all noise and distortion that may have crept into the audio signalPower Control to send power on/off signals to other connected McIntosh components (such as CD Players, turntables, tuners and media streamers) for easy system power up and shutdownOur patented Solid Cinch™ speaker binding posts that easily but securely attach the speaker cables to prevent them from coming loose and possibly causing a short; the binding posts are also gold-plated to prevent corrosion and ensure a quality signal is sent over your speaker cables

RB-1552 MkII is built upon the same platform as the RB-1582 MkII with only a slightly smaller power output capability at 2 x 130 Watts. The RB-1552 MkII is a 130 Watt per channel class AB amplifier. It is engineered to be powerful and robust, yet able to extract every last nuance out of even the most complex musical score.  Notable features of the amplifier include independent left and right power rectification stages and decoupling. The layout is essentially a mono block design. Further evidence of design over-spec is in the selection of premium “slit-foil” capacitors, which provide plenty of reserve energy for extremely dynamic audio passages and are able to quickly replenish themselves due to the nature of their unique design. Input options are balanced XLR or unbalanced RCA connectors. The RB-1552 MkII stereo amplifier has been engineered to provide high-resolution audio performance, yet it is very affordable, as has been the tradition with Rotel electronics for over 50 years.
