Under the leadership of Frank Blöhbaum, developer of Thorens electronics and the self-bias control of TAC tube amplifiers, the circuit design was completely revised and improved. Therefore, in the output stage section a 90° phase reserve was achieved by making several changes. This phase reserve provides much better transient response to complex loads (speakers). Because the amplifier virtually always operates during normal operation in the state of transient oscillation (music represents transient pulses), the improvements can be heard in elementary form. The musicality and sound are much better than its predecessor. Even the most difficult speakers can be powered easily. The amplifier always dominates the complex load (speaker) without sounding forced.
The preamplifier section was installed in the second stage with 6N1P tubes. The higher voltage level provides better signal stability. This results in greater spectral purity of the signal causing further improvement in fine details of the sound. Here, the tube-like musicality is maintained and an analytical coldness to the sound never arrives. Another advantage of the improved circuit design is a greatly improved signal-to-noise ratio. It results in excellent playback quality also on high-efficiency speakers such as the Impulse series from Dynavox : the noise was once. Enjoy an explosive live performance as a result of excellent dynamics. Additionally, the volume control has been fine-tuned. By Therefore, the volume level can be set precisely by remote control.
