The 2012 CES

For the 2012 CES show we will proudly unveil our new Medusa and Hydra Tube/Class D power amplifiers! We will be pairing these with our Hera II preamp to power the venerable Andra III loudspeakers from Eggleston Works. Cabling will be provided by TEL Wire. For our sources we will be streaming digital as well as spinning LP's on a very high-end turntable. If you are planning on attending the show be sure to visit us in the Venetian Hotel room 29-225

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 250WPC into 8 Ohms and 500WPC 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.

Available at select Rogue Audio dealers in January 2012.

"Not that science has anything to do with it."

Wouldn't science say that lots of high gain tubes in the output stage of a power amp are more problematic in general from a maintenance and cost perspective, both of which affect the end user?

Making the benefits of tube sound more affordable and usable for the masses seems to be the profound design goal here. On paper at least, I'd say mission accomplished!

My local dealer sells Rogue and the gear there always sounds great. I'm very much looking forward to hearing these sometime soon. They would seem to fit very nicely into either of my systems down the road if ever needed.
I have found that the combination of a Modwright tubed pre-amp and Wyred 4 Sound Class D monoblocks gives me the best sound for my money so far. I would have to spend considerably more money to get a top quality SS or tubed monoblock. I trust that Rogue knows their stuff and that the pre-amp and amp will work well together. The Class D amps are easier to maintain and should last a long time and you can try different tubes in the pre-amp section to taste. It may be the integrated of the future.
I think I read the input impedance of the new Rogue amps is 200K ohms, which would make it most well suited for use with most any tube or ss pre-amp.
