Unison Research Discontinued

A Unison Research component lands on this page when Unison stops building it. That covers the Sinfonia, S6, Triode 25, Preludio and Simply Italy tube integrateds, the hybrid Unico 90 and Unico Due, the Unico CD Uno and Unico CD Due CD players, and the SH headphone amplifier. Their pages stay live so owners and second-hand buyers keep the full specs in one place.

Three of those amplifiers live on as Black Editions. Unison makes the Simply Italy Black Edition, Triode 25 Black Edition and S6 Black Edition today, and the Unico Nuovo is the closest current Unico to the Due in price. Everything else we carry from Unison today, from the Unico hybrids to the Reference monoblocks, is in the main Unison Research collection.
