Imagine a new kind of amplifier that combines the best of both the solid state and tube 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 the solid state. Such an amplifier now exists! Critics are already using words like "Groundbreaking" and "Revolutionary" to describe our new tube/Class D hybrid amplifiers.

These new amplifiers are much more than simply a tube circuit placed in front of a class D output section.  Our 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 Hydra and Medusa deliver 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.

The Atlas Magnum was designed to box outside of its weight class and in that spirit it is truly a world champion. Handily outperforming amplifiers costing many times its price, the Rogue Atlas sets a new standard in affordable tube amplification. With circuitry borrowed from our most advanced amplifier designs, the Atlas effortlessly conveys the detail and nuance of even the most complex musical passages. And with 100 WPC of pure tube power on tap, the Atlas is capable of realistic volume levels that will rival the clarity and presence of the original performance.

From a technical standpoint, the Atlas represents the cutting edge of tube amplifier design. An oversized linear power supply stores tremendous energy for the dynamic headroom great performances demand. The tube circuitry is first rate with short signal paths and low noise design. Finally, precision components are used to provide the transparency and air that are so critical to accurate musical reproduction.

In the recent past we have quietly built some very special amplifiers for critical product launches. These amps were built for other audio companies who wanted to showcase their most expensive loudspeakers and components at important events such as the CES. These industry insiders recognized just how good the Apollo monoblocks already were but asked us to take them a step further. Our response was the Apollo "Dark" monoblocks. Using the Apollo platform as the basis, we enlarged and improved the power supply and made numerous circuit and component upgrades that significantly improve the transparency and dynamics of an already excellent amplifier.

Based on the overwhelmingly positive response within the industry, we have decided to make the Apollo Darks available to select retailers.

Power, Grace, and Precision -- when you are ready for the ultimate in vacuum tube amplification, look no further than the Rogue Audio M-180 monoblocks. With 180 Watts of pure tube power, these monoblocks stunningly accomplish the impossible. After drawing the curtains aside on a soundstage of full height, width, and depth, the pace and musicality of the M-Series provide a riveting performance that will leave you breathless. And along with their profound sonic merits, the monoblocks are aesthetically exquisite amplifiers that will stoically serve as the cornerstones of your system. 

Using circuitry derived from our Apollo amplifiers, the M-180s are marked by an exceptional design that places it squarely at the forefront of tube technology. Just a few of the notable features are a "slow start" logical turn-on for extended tube life, a massive high capacity power supply, and the ability to externally switch between either ultra-linear or pure triode operation.The highly efficient design also means cool running and greatly extended tube life. Other refinements include balanced (XLR) and RCA inputs, mechanically isolated transformers, matched octets of KT120 output tubes, and separate 4 and 8 ohm taps on the rear. In keeping with Rogue Audio's "quality by design" philosophy, only the finest components are used in the construction of these remarkable amplifiers. See for yourself why the M-180 monoblocks are a Stereophile Magazine "Class A Recommended Component."

Stereo 100     $3,495.00

Elegant and refined, yet brutally powerful, Rogue Audio's flagship monoblock amplifiers have raised the bar for reference level amplification. The Apollo's ability to reveal the finest musical details while providing seemingly limitless dynamics are the hallmark of the finest amplifiers we have ever produced. Whether your passion is jazz, rock or symphonic works, these amplifiers will provide the clarity and dynamics to closely rival the original performance.

That these pure tube amplifiers boast a continuous power output of over 250 watts is but a small part of the story. Designed and engineered without compromise, the Apollos boast ruler flat frequncy response, tremendous bandwidth, huge dynamic range, and vanishingly low levels of distortion. And the enormous LC power supplies enable the reproduction of musical transients at far beyond the amplifier's rated output. With a unique and tasteful appearance, the Apollo chassis' are constructed using CNC machined aluminum faceplates and body panels. The ultra-high tolerance electronics components and huge transformers contribute to the peerless build quality. Features include an on-the-fly switch offering either Triode or Ultralinear operation. A second standby switch allows the amplifier to remain warmed up and ready for immediate use between listening sessions. A built in meter and individual bias switches makes tube biasing a snap even for the tube novice. The rear panel contains balanced and single ended inputs as well as 4 and 8 ohm Cardas binding posts.
