CAD-805RS Vacuum Tube Mono-Block Power Amplifier (pair)

Considered by The Absolute Sound as one of the ten most important amplifier designs of all time, the CAD-805 continues its legacy with the Reference Series CAD-805RS, epitomizing SET mono-block amplifiers' excellence. Its circuit and parts upgrades ensure it remains at the benchmark for SET audio performance. SET amplifiers, characterized by their pure Class-A operation, distinguish themselves from other amplifiers, showcasing a harmonic richness that sets them apart. Please note that all SET amplifiers are pure Class-A, but not all Class-A amplifiers are SET.

SET enthusiasts praise the CAD-805RS for its holographic soundstage, harmonic richness, and lush midrange, delivering an immersive listening experience across music genres such as jazz, vocal, and classical. With the flexibility to choose between the included 845 and 211 output tubes, you can tailor your sound preference to either a rich, lush sound or a more linear, powerful profile. Experience the magic of music like never before with the CAD-805RS—where every note resonates with unmatched clarity and depth.


The CAD-805RS comes standard with removable cage covers.
