Musical Fidelity have decades of experience in building and designing quality Hifi equipment and the MX-HPA is the latest and if you believe the hype the greatest headphone amplifier the company have every produced.

The Musical fidelity MX-HPA is a fully balanced, studio quality headphone amp which delivers superb performance above and beyond the previous M1-HPA and offers an incredibly low distortion (less than 0.005%) and an excellent signal-to-noise ratio, which is better than 120dB (making it 'A' weighted).

The unit features two inputs, balanced and single ended, which can be easily switched between. There is also gain switching, to allow boost for higher impedance headphones, so the unit is compatible with all dynamic headphones regardless of impedance.

The front panel XLR/JACK sockets are dual purpose, you can use either one or two pairs of standard 6.25mm/¼" stereo jack-terminated headphones or a single pair of headphones, terminated in two three-pin male XLR plugs. The necessary single ended/balanced mode switching is carried out automatically on connection of the headphone(s). An incredible balanced headphone amplifier which delivers stunning performance.
