Groundbreaking Triode/Class D Hybrid Amplifiers!

Imagine a new kind of power amplifier that combines the best of both the tube and solid state technologies. An energy efficient "green" design requiring no tube biasing or regular maintenance. An amplifier having the smooth and organic sound that only tubes can provide combined with the dynamics and slam of a damping factor of over 1000. Such an amplifier now exists! For 2012 Rogue Audio proudly introduces the Medusa and Hydra tube hybrid amplifiers. Utilizing breakthrough technology developed by Rogue Audio these amplifiers provide outstanding performance in a compact and cool running design. The Medusa is conservatively rated at 200WPC into 8 Ohms and 400WPC into 4 Ohms while the Hydra is rated at 100/200WPC. Both amplifiers feature a triode tube front end combined with a class D Mosfet output section that offers incredibly smooth and transparent sound with none of the fatigue often associated with earlier class D amplifiers. Priced at $3,995 and $2,995 respectively they also afford the excellent value Rogue Audio has come to be known for.

I purchased this power amp to drive a pair of Revel Performa3 M105s. I have it paired with an Ayre Acoustics K-5xeMP Preamp. The Hydra is super detailed with a deep soundstage. It sounds solid state and does not deliver that tube warmth that you might expect. Some care is required in choosing the right preamp. Any unit will not suffice to get the most out of the Hydra. I listened to 4 different preamps ultimately arriving on the Ayre. Once you find the right preamp though, this is a truly awesome power amp.
