NAD M28 Seven Channel Power Amplifier
A serious theater or media room needs power that stays clean when every channel is working.
When the Processor Is Good but the Room Still Feels Held Back
Many theater systems run into the same problem: the processing, speakers, and room plan are capable, but the amplifier section cannot keep up. Effects lose focus, dialogue gets buried, bass feels disconnected, and the system sounds smaller than the room should allow.
That is especially noticeable when all channels are active. A properly designed surround system needs consistent power, not just an impressive number on a spec sheet with one or two channels driven.
Seven Channels of Serious Control
We chose the NAD M28 because it gives a high-performance theater or media room the dedicated amplification it deserves. With seven channels of Purifi Eigentakt amplification, it is built to drive demanding multichannel systems with clarity, control, and headroom.
Pair it with a processor like the NAD M17 V2i, and the M28 becomes the power foundation for a proper separates-based theater. It keeps processing and amplification separate, which helps the system stay flexible as formats and source technology change.
What the Specs Won't Tell You
All Channels Matter
The M28 is rated for 200W per channel with all seven channels driven into 8 ohms. That is important because movie soundtracks do not politely ask only two speakers to work at a time.
When the room gets busy, the amplifier has to keep each channel clean, controlled, and ready for dynamic swings. The M28 is built for that kind of real multichannel demand.
Power Without the Heat Penalty
Traditional high-power theater amplifiers can be large, hot, and difficult to place in a rack. The M28's Purifi Eigentakt design gives it serious output while running cooler and staying more manageable than many older amplifier designs.
That makes a difference in custom installations. Less heat, cleaner rack planning, and reliable trigger control all help the system work better day to day without adding unnecessary complexity to the home.
A Better Match for Serious Processing
A processor like the M17 V2i can only do its job if the amplifier can preserve the detail, timing, and channel separation coming from it. The M28 gives each channel a cleaner, more controlled path to the speakers.
That is where separates begin to make sense. The processor handles decoding and room correction, while the amplifier focuses on clean power across the full speaker layout.
Expert Consensus
Home Theater HiFi - Home Theater HiFi praised the M28 for delivering continuous power across seven channels while staying cool and controlled. The review highlighted its clarity, large soundstage, dialogue intelligibility, strong movie performance, and natural pairing with NAD's M17 V2i processor.
Sound & Vision - Sound & Vision described the M28 as a unique high-end amplifier designed to compete sonically with some of the strongest amplifiers on the market, regardless of channel count. The review also noted its build quality, balanced and unbalanced inputs, 12V trigger, and all-channels-driven power rating.
The Audio Two Verdict
The NAD M28 is for the client building a serious theater or media room around separates, not a one-box receiver hidden behind a premium room design. It makes the most sense when the speakers, room, and processor are good enough that amplification has become the limiting factor.
We would pair this with a proper surround processor, carefully chosen speakers, and a room that has been planned around seating, sightlines, cabinetry, speaker placement, and calibration. If the goal is a cleaner, stronger, more controlled theater system, the M28 is the kind of amplifier that lets the rest of the design do its job.
