Rogue Audio Medusa tubed/class-D hybrid
At CES, Rogue Audio introduced the Medusa, a 200Wpc tubed/class-D hybrid amplifier ($3995) that combines a triode front-end with a class-D MOSFET output section. O’Brien’s goal was to create an energy-efficient, “green” design that would circumvent the need for regular maintenance and tube biasing. Also available now is a 100Wpc version, the Hydra ($2995). O’Brien is also working on an integrated amplifier using the same hybrid technology. “We hope this will satisfy a lot of people’s needs,” he said.
Along with the Medusa amplifier, the system on hand included Rogue’s Hera preamplifier, Tel Wire cables, EgglestonWorks Andra 3 loudspeakers, and a Spiral Groove turntable. Even while standing behind a partition on an upper level of the suite, the music sounded detailed and nuanced, relaxed and involving.
