Master Line Stage
Preamplifier
The design of the all-new VAC Master Preamplifier takes the essential developments from the cost-no-object Statement pre-amplifiers and presents them in their most elemental, effective forms. If the Statement products might be likened to Formula 1 racecars, the Master Preamplifier is the derivative ultra performance road-going sports car.

Hi-end Audio / Patented iQ technology / Valve Amplifiers / Made in U.S.A
VAC was founded in 1990 by Kevin Hayes and his father, Channing W. Hayes in Sarasota, Florida. With their specialty on valve amplifier design, VAC makes their first major leap – awarded as the OEM manufacturer to produce some of the classics valve amps: Marantz Model 7 / 7C, Model 8B, Model 9. After the foundation on OEM on Marantz valve amplifier, VAC returned to design and produce quality valve amplifier.
