The Unison Research S6 Black Edition brings a bold new aesthetic to a revered tube amplifier design, delivering the warmth and musicality that made the original a standout. Featuring six EL34 tubes in a parallel single-ended configuration, the S6 produces 30W per channel of rich, harmonically dense sound with the natural midrange that tube lovers crave. The upgraded Black Edition boasts refinements in internal components and a striking matte black finish, offering both sonic and visual sophistication.
