SV-237MK

tubeLine

Class-A Hybrid Integrated Amplifier

How to improve an unbeatable unit? Very easy, just listen to the customers wish. That’s how the SV-237 becomes the SV-237MK. The big change is that we replaced the USB input on multiple wish by an 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.
