An excellent Class A headphone amplifier and DAC from PS audio. This amp will really get your favorite headphones singing.

I have powered the ZMF Eikon, Auteur, Verite Open, and Verite Closed and they all sound fantastic. I also found there to be great synergy with the Hifiman Sundara.

Can swing a huge amount of power and has incredible control, detail, and transparency. A real tank, with an overbuilt power supply and a heavy case, this thing was built to last!

This retailed at $1000.

Comes with original packaging.
