The MX HPA fully balanced headphone amp is the result of decades of experience of making high quality headphone amplifiers. Relatively, the MX HPA has about the same performance into headphones as the incredible Titan has into loudspeakers. That is; awe inspiring, incredible, limitless and any other hyperbole you can imagine. It is really incredible.

Design and build specifications The MX HPA’s technical performance is stunning.  Typically distortion from 20 Hz to 40 kHz is less than 0.005%.  This is serious stuff.  Signal noise ratio is better than 120dB (‘A’ weighted).  Needless to say frequency response is ruler flat from 10 Hz to 20 kHz (-0.1dB). 

It is capable of a short term peak of 10 watts (for one cycle).  It has 2 gain positions; 18dB (8X) and 24dB (15X).  Inputs are either balanced or single ended.  It will automatically convert single ended inputs to balanced. The MX HPA is genuinely fully balanced from beginning to end.
