A tube integrated amplifier runs your source through a vacuum-tube signal path and a matching power stage in one chassis, delivering the harmonic richness, midrange presence, and three-dimensional soundstage that solid-state designs chase. Because the preamp and power sections are matched and built together, a good integrated removes the guesswork of pairing separates while keeping the valve character intact. This collection gathers all-tube integrateds hand-built by the specialist valve makers we carry, from entry-level single-ended designs to high-power push-pull flagships. Each is a complete valve system in a single box, ready to drive a wide range of loudspeakers.
Current highlights include Rogue Audio's Cronus Magnum III, which pairs a triode preamp with KT120 output tubes and switchable ultralinear and triode modes, and Unison Research's range from the entry Simply Italy to the single-ended 845 power of the Simply 845.
