The VT-series microphone preamplifiers will change the way you think of audio quality. The transparency is astounding. Vocals sound smoother, warmer, more intimate, with a compelling presence. Any microphone and any sound will benefit from the improved clarity, definition, and lack of solid-state artifacts.

Single channel vacuum tube microphone preamplifier - The VT-1 recreates the sound of classic tube preamps of the 1960s. Modern components and computer-optimized circuitry, unavailable during the vacuum tube era, elevate this design to a new level of performance.
