Excellent condition audiophile headphone amp with very low hours. Incredibly powerful Class A amp that can drive extremely demanding headphones with ease. Also has a DAC that works pretty great and connects to your computer via USB for great audio quality. No visible blemishes under normal lighting as you can see in the photos. Here is a review of the amp it used to be $800. Highly recommended for someone who has demanding headphones and wants the power of a class A amp. https://www.enjoythemusic.com/magazine/equipment/0214/musical_fidelity_m1_hpap.htm Comes in its original box and packaging with manual, power cable and USB wire.

In very good condition, hardly used. Original box and packing are not included.The M1 HPA consists of a pure class A circuit giving exceptional performance into virtually any impedance headphones. It features a line as well as a USB input, and a line (loop) output. It also features two headphone sockets and a set of volume-controlled outputs to enable use as a preamplifier.
