DESCRIPTION

MX-HPA is a fully-balanced headphone amplifier, by Musical Fidelity.

Years of experience in making high quality headphone amps have been distilled into the design of the MX-HPA. As a result, this fully-balanced headphone amp offers an awe-inspiring listening experience.

The MX-HPA technical performance is stunning. Typically, distortion from 20 Hz to 40 kHz is less than 0.005%. Signal-to-noise ratio is better than 120 dB (A-weighted). Frequency response is ruler-flat from 10 Hz to 20 kHz (-0.1 dB).

The MX-HPA is capable of a short-term peak of 10 watts (for one cycle) and has two gain positions: 18 dB (8X) and 24 dB (15X). Inputs are either balanced or single-ended. The MX-HPA will automatically convert single-ended inputs to balanced. The MX-HPA offers a genuinely fully-balanced design from beginning to end of the entire signal chain.
