Musical Fidelity MX-HPA - Headphone AmplifierYears 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 HPAs technical performance is stunning. Typically, distortion from 20 Hz to 40 kHz is less than 0. 005%. Signal to noise ratio is better than 120dB (A weighted). Frequency response is ruler flat from 10 Hz to 20 kHz ( 0. 1dB).

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

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