How to improve an unbeatable unit? Very easy, just listen to the customer's wish. That’s how the SV-237 becomes the SV-237MK. The big change is that we replaced the USB input on multiple wishes with coax and optical input. These inputs are more suitable for daily use and offer more possibilities for connections. The unique circuit of Frank Blöhbum was not changed.
Under the leadership of Frank Blöhbaum, who is the developer of the Thorens electronics and the Auto-Bias control of the T.A.C. tube amplifiers, the circuit design was completely revised and improved. Thus, in the output stage section, a phase reserve of 90° was reached by making various changes. This phase reserve provides a much better transient response to complex loads (loudspeakers). Because the amplifier always works virtually during normal operation in the state of transient oscillation - Music represents transient pulses – the improvements can be heard elementary. Musicality and sound are much better than its predecessor. Even the most difficult loudspeakers can be powered easily. The amplifier always dominates the complex load (loudspeaker) without sounding strained.
