MX-HPA Headphone Amplifier
MX-HPA Headphone Amplifier
$1,525
Superb headphone amplifier
Enjoy fully balanced performance with this outstanding headphone amplifier.
Local pickup or $11 flat rate shipping within Australia
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.
Why do you need one?
Anyone who listens seriously on headphones at home must eventually discover the limitations of a computer or smartphone headphone output, or, if they are still using one, an old-style hi-fi integrated with headphone amp built in. Most headphone amps are likely going to be a significant compromise, given the size/space and power limitations they have to work with. A stand alone headphone amp has much more space to dedicate to better circuitry, and a more robust power supply, allowing both overall better controlled sound and, importantly for some headphones, the ability to provide considerably more output power to the headphone.
The key is that amps need to deliver enough power for the headphone not to sound distorted at the musical peak—not the average volume. The purpose of a headphone amp is not to blast your ears into deafness! It’s to have the sound you hear be cleaner and more controlled, especially during peaks. But you should always practice safe listening, and keep the volume at a very comfortable level.
This new wave of balanced headphone amps provide a more refined and engaging sound performance experience to make the most of the controled enviroment that is headphones.
