The remarkable studio reference MX HPA, a fully balanced headphone amplifier, has been a project filled with passion for everyone at Musical Fidelity. As some of you may already know, we have been producing headphones for quite some time and have always been enthusiastic headphone enthusiasts. While the M1 HPA is a very good product, we aspired to create something truly exceptional.

The MX HPA, a fully balanced headphone amplifier, represents the culmination of decades of experience in crafting high-quality headphone amplifiers. In relative terms, the MX HPA delivers headphone performance comparable to what the incredible Titan achieves with loudspeakers. It’s awe-inspiring, extraordinary, boundless, and every other superlative you can think of. It’s truly remarkable.

The MX HPA boasts stunning technical performance. Typically, distortion from 20 Hz to 40 kHz is less than 0.005%, which is an incredibly low figure. The signal-to-noise ratio exceeds 120dB (A-weighted). Needless to say, the frequency response remains perfectly flat from 10 Hz to 20 kHz, with only a minimal deviation of -0.1dB.

This amplifier is capable of a short-term peak of 10 watts for a single cycle. It offers two gain settings: 18dB (8X) and 24dB (15X). Inputs can be either balanced or single-ended, and it automatically converts single-ended inputs to balanced. The MX HPA is genuinely a fully balanced amplifier from start to finish.
