If you've only ever heard your headphones plugged into an everyday amp, or a computer, the M1 HPA will be a revelation.
It's a dedicated headphone amplifier capable of driving any set of cans to unprecedented levels of performance. Whatever your source, you'll hear the music open up, revealing greater scale, extension and detail.
The secret to the M1 HPA's stunning sound is its pure Class A amplifier design, which is paired with a high-current, low-noise power supply. This combination gives the M1 HPA the ability to drive any headphone without distortion.
Its talents don't end there: the M1 HPA also functions as a high-quality pre-amplifier.
The M1 HPA has already received much acclaim: the Hi-Fi Choice review stated "you might have to pay fives times the HPA's asking price to significantly better its performance", while the Hi-Fi News group test concluded: "on excellent sound, facilities and value for money, the M1 HPA is a clear winner."
M1HPA - Design and Build
The M1 HPA builds on years of headphone amp expertise to deliver a product that will transform your solo listening sessions.
Its pure Class A design delivers the same outstanding sonic characteristics with headphones as full-size Class A amplifiers do with speakers. Not heard a Class A amp before? Expect to enjoy a richer, fuller, smoother sound, with greater bass extension.
As the Hi-Fi Choice review of the M1 HPA puts it: "Choose your headphones wisely and you'll have a package that rivals the sonic performance of large ultra-expensive speakers and amplifiers".
The M1 HPA has both line-level and USB inputs and a loop-out facility. It also has a variable line output, so it can be used as a high-quality single pre-amplifier: perfect if you're streamlining your system.
The combination of the pure Class A design and high-current, low-noise power supply enables the M1 HPA to achieve excellent technical performance. Distortion measures at less than 0.0005% across the band, and frequency response is ruler flat. Signal to noise ratio is also outstanding.
Unlike many other headphone amplifier manufacturers, Musical Fidelity has also carefully considered output impedance, ensuring the M1 HPA is capable of driving any headphone with complete linearity.
Hi-Fi News highlighted this power and poise in its headphone amplifier group test: "The HPA enjoys the lowest 1ohm source impedance and is capable of sustaining a full 1W into low impedance (30ohm) cans. It's the beefiest can-driver of our group!"
Finally, the M1 HPA has twin headphone sockets on its front panel. That means you can share the experience with another headphone lover, or keep all that excellence to yourself, using the two sockets to seamlessly switch between different pairs of your favorite cans.
