Direct Heated Tubes (DHT)
The superiority in linearity of Direct Heated Tubes (common cathode to filaments) is well known, to all manufacturers, if we consider that all top of the line, tube amplifiers use DHT for output. In our final amplifiers we use only two stages of amplifications and both are implemented around Direct Heated Tubes. The line amplifier uses only one stage again with DHT. Benefits from this approach, are better dynamics, imaging and tonality.
