Founded in 1975 by Richard Fryer in Silicon Valley, Spectral Audio drew on advanced instrumentation techniques from the tech revolution to pioneer ultra-fast, wide-bandwidth solid-state audio components, starting with the MS-ONE preamplifier. The company benefits from the expertise of recording engineer and circuit designer Keith O. Johnson, operating more as a research laboratory than a traditional for-profit enterprise, producing limited quantities of high-end electronics renowned for resolution, responsiveness, and musical realism.
