SV-237MKII

tubeLine

Class-A Hybrid Integrated Amplifier

The third edition of our successful model is presented in a completely revised design. The SV-237 MKII appears more modern and elegant than its predecessors. Modern now also with the connection possibilities. In addition to two digital inputs, there is also a Bluetooth input on board. The unique circuit was developed by Frank Blöhbaum, who uses two 6N1P NOS tubes in the preamp section, which give the sound naturalness, musicality and warmth.
