MX-HPA | Headphone Amplifier

The MX-HPA is a fully balanced ultra performance headphone amp.

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.
