We develop and realize high quality audio reproduction. Many of our clients like to construct excellent valve amplifiers as part of their DIY activity. These are the main ingredients for this new single-ended stereo valve amplifier. We present it as a half kit; some of the work is already done, other is true DIY and a joy to build.
In its development we focused on the music reproduction in the most transparent way. Traditional valve amplifier designs use feedback across the transformer, or no feedback at all. Both methods have their flaws in terms of distortion reduction and maintaining the correct damping factor.
Our research resulted in the so called Trans-Technique which we applied in this amplifier kit. By means of current steering techniques plus DC-coupling, the power tube is converted into a low impedance low distortion driver of the output transformer. Low impedance drive is essential for smallest magnetic distortions inside the output transformer.
The total result is a transparent sound stage with a correct stereo, depth and height image. Its' character is pure and embracing. The bass reproduction is unlike with many valve amps detailed and quick. Micro details from instruments, voices and surrounding spaces remain intact.
