Rogue Audio Medusa Power Amplifier



This amplifier is much more than simply a tube circuit placed in front of a class D output section. Rogue’s proprietary tubeD circuit topology actually integrates the tube section into the amplifier yielding the smooth natural sound that only a tube amp can provide. With almost uncanny accuracy the Medusa delivers stunning dynamics and transparency without any of the edgy, etched or grainy sound that often accompanies solid state designs.

A low power standby mode allows critical amplifier sections to remain continuously powered on if desired and a slow start feature allows the tubes to warm up gradually to eliminate turn-on noise and greatly extend tube life. Three massive linear power supplies are used to power the amplifier circuitry and ultra-high quality parts are used exclusively throughout the design.

Combined with a stunning appearance, you can be certain that you are investing in an amplifier that truly represents the very leading edge of audio technology.
