NAD M28 Seven Channel Power Amplifier
The NAD M28 Seven Channel Power Amplifier is built for reference-level home theater systems that demand effortless power, ultra-low noise, and true speaker control across every channel. Using Purifi Eigentakt™ amplification with NAD’s custom implementation, the M28 delivers explosive dynamics with refined detail—keeping dialogue locked, effects impactful, and music natural and textured. With 200W per channel (all seven driven) and massive dynamic headroom, it stays composed through demanding scenes while maintaining consistent tonal balance across real-world speaker loads. Balanced XLR and unbalanced RCA inputs, rugged binding posts, and a compact rack-friendly chassis make it ideal for premium installs, while a 12V trigger input supports seamless system automation.
The NAD M28 is part of ListenUp's NAD Power Amps Collection.

NAD M28 Q&A:
- What is the NAD M28 designed for?
- The M28 is designed for high-end home theater and multichannel audio systems that need powerful, clean amplification across seven channels.
- How much power does the M28 deliver per channel?
- It delivers ≥ 200W per channel with all seven channels driven (8 ohms, 20 Hz–20 kHz), ensuring consistent output across the entire system.
- Does the M28 support both balanced and unbalanced connections?
- Yes. It includes balanced XLR inputs for long, noise-resistant runs and unbalanced RCA inputs for flexible system matching.
- What makes Purifi Eigentakt™ important in this amplifier?
- Purifi Eigentakt™ is known for extremely low distortion and high linearity, helping the M28 sound transparent, controlled, and natural even under heavy load.
- Will the M28 work well with difficult speaker loads?
- Yes. The M28 is designed to maintain a flat, stable response across varying speaker loads, keeping the sound consistent and tonally balanced.
- Does it include automation features for custom installations?
- Yes. A 12V trigger input allows the M28 to integrate with AV processors and control systems for automatic power on/off behavior.
- How efficient is the amplifier in standby?
- The M28 is rated at ≤ 0.5W standby power, and it can enter standby after ≤ 30 minutes with no input signal.
- Is the M28 suitable for rack installations?
- Yes. It’s built with a compact, rack-friendly form factor intended to fit cleanly into custom multi-channel setups.
