Description Musical Fidelity MX-HPA Headphone Amplifier The Musical Fidelity MX-HPA Headphone Amplifier’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 headphone amp is genuinely fully balanced from beginning to end.
