KINGSOUND M-20 Vacuum Tube Amplifier for Electrostatic Headphone Silver - reviews - There is 1 review.

Unique device
This is really a unique device, classic and solidly constructed, reminiscent of the Japanese from the 60s or 70s.
The sound quality is stunning, just as you would expect from a tube device, incredible resolution and dynamics, deep black in the breaks.
A secret type. I would just like a more stable cover (like the Cayin devices) for the tube and non-slip feet.
