Low hours (less than 100) unit with tube and power Cable . Great amp just no time to listen anymore. Here is the stuff from their site;


The first self-made fully balanced headphone tube amplifier with toroidal audio transformers

The amplifiers operate in ‘A’ mode
There are a lot of modes of operation of amplifiers, such as A, B, AB, C, D ... ‘A’ mode stands apart from all others, because only this mode is designed for high sound quality at the expense of power. The rest of the modes operate to get maximum power at the expense of sound quality.

Toroidal Audio Transformers
The most critical part in the tube amplifier is a sound transformer. We decided to use such exotic things as toroidal audio transformers. This is the most complicated part, toroidal transformers take approximately 80% of the time required for the manufacturing of the device, but they sound great.

Triodes
We only use triodes, because they have the lowest internal resistance, which has a positive effect on the quality of sound.
