serves double duty to check the bias of the four KT150 output tubes. The convenient remote control puts

Performance-wise, the VSi75 is in an entirely different league from the competition for a number of reasons.
It’s wide bandwidth output transformers and proprietary coupling caps are found in the revered Reference
75SE, and the power transformer is designed around the KT150 output tube. The resulting sound is striking.

able to develop an immense sound stage. You feel a very real connection with the musician, in a way normally
reserved for a live event. The VSi75 sounds very much like the amp from which it borrows, the REF 75SE, with
an immediacy, delicacy and focus that is captivating.
