VSi60 Integrated Amplifier

The VSi60 clearly proves that you do not have to spend a fortune to enjoy truly great sound at home. Built by hand in Plymouth, Minnesota, to the same exacting standards as Audio Research’s renowned Reference series, the VSi60 offers remarkable sound quality and value.

The VSi60’s resolving power is surprising, allowing you to hear details that were previously hidden in your recordings, but that resolution is in service of the music — grainless, tonally accurate and refined.
