P701 Hypex Ncore MonoBlock Amplifier

The P701 is March Audios' most powerful mono-block amplifier. In a matching enclosure to the stereo amplifier range and DAC1, this simply elegant product is milled from solid aluminium with a tough anodized treatment. Exceptional fit, finish and build quality.

The Mono-block format eliminates any possibility of crosstalk potentially found in stereo amplifiers.  The dedicated 1.2kW power supply minimises load related voltage modulation.  The format also allows placement at the speaker permitting speaker cables to be as short as possible.


Featuring Hypex Ncore NC1200 technology, it delivers ultra low distortion, noise and high power output in a compact format.  Ncore® is the first Class-D amplifier not just to nudge the best linear amplifiers, but to surpass them in every aspect relevant to sound quality. If you want the ultimate in clarity, resolution and musicality, there is no longer a reason to trade efficiency or compactness.

The class leading technical performance delivers a neutral but captivating musical sound that will suit the finest partnering equipment.  Fully 2 ohm capable with ultra low output impedance, the P701 can deliver up to 1200 Watts and 40 Amps ensuring tremendous grip and drive even with the most challenging of speaker loads.

The P701 features touch power switch, balanced Neutrik XLR inputs (compatible with single ended RCA*), and heavy duty tellurium copper silver plated ETI Research speaker binding posts.  High quality Canare speaker cable and Mogami signal cable is used internally providing the best signal integrity and shielding. Input RF filters ensure freedom from intermodulation.  Suitable for use directly driven from high quality DACs or Pre-Amplifiers.

Hand built and individually tested, the P701 is backed up with a 3 year warranty.
