About the Medusa

The Rogue Audio Medusa is a high-power hybrid stereo amplifier that integrates two hand-selected Russian 12AU7 tubes in the input stage with a proprietary, extensively modified Class-D output stage based on Hypex UCD-400 modules. It delivers 200 watts per channel into 8 ohms and 400 watts into 4 ohms, with a frequency response of 5Hz to 30kHz (+/-1dB) and total harmonic distortion typically under 0.1%. The amplifier uses a linear power supply with beefy toroidal transformers and added capacitance to ensure strong bass performance and stable power delivery. Its high input impedance of 200 k-ohms ensures easy driving by virtually any preamplifier or source. The Medusa offers balanced XLR and unbalanced RCA inputs, five-way binding posts for speaker connections, and an IEC power inlet. The front panel features a simple power button that puts the amp into standby mode, preserving tube life by turning off the input section while keeping output electronics warmed up. The amplifier is built with high-quality hand-assembled construction, weighs about 36 pounds, and is available in black or tinted silver finishes. It is praised for its clear, airy, and dimensional soundstage, tight bass, detailed top end, and the ability to drive a wide range of speakers with low noise and heat output. The Medusa is considered an outstanding value for a high-end audiophile amplifier at its price point around .
