Description

I'm selling my Fosi Audio MC331 tube headphone amplifier. I bought it about 1–2 years ago and have used it lightly — it's in excellent condition and still under warranty. It works perfectly, powers headphones cleanly with the warm tube sound, and has volume, gain and balance controls along with a VU meter. The unit comes with the original power adapter and tubes installed. Ideal if you want to add tube warmth to your headphones without any fuss.
