Rogue Audio Atlas II Power Amp

1 Review

Vacuum tube audio amplifiers have long been recognized by the audio community as providing significantly better sonics than solid state transistor-based designs. Unfortunately, well designed vacuum tube products are much more expensive to produce than their solid state counterparts. As a result, this superior technology has only been available to a small but fortunate group of audio enthusiasts. Enter Rogue Audio. Our amplifier designs combine the finest in tube-circuit topology with meticulously engineered circuit layout to achieve superior performance. Unflagging attention to the integrity of the audio signal path and power supplies results in truly superior designs. The most discriminating audiophile will delight in the impeccable fidelity of recordings reproduced through our amplifiers. The Titan series of products presented us with a significant engineering challenge; to create truly high end products at entry level prices. We believe we have succeeded! The Titan series offers outstanding performance and build quality that is accessible to almost anyone with a love for great sounding music. Entirely hand built in the USA, the Titan products are assembled to the same exacting standards as our most expensive amplifiers. Since their introduction last year they have won numerous industry awards. Magnum Upgrade Details The "MAGNUM" versions of the Titan series features significant parts upgrades that improve performance in your Atlas, Metis or Cronus in a number of important ways. Increased transparency, greater dynamics, improved bass and high frequency response, as well as a smoother and more refined presentation are all part of the Magnum upgrade. The extensive power supply mods permit the use of the KT120 power tube which increases the rated output power of the Atlas and Cronus to 90WPC! Please note that all of our current products other than the Titan series already use Magnum type parts. The Magnum package consist of the following modifications:
  • Larger power supply
  • Power supply mods
  • Polypropylene bypass capacitors
  • Precision Dale-Vishay resistors in critical spots
  • Upgraded binding posts
  • Gold tube sockets
  • Upgraded small signal tubes
  • KT120 output tubes
  • Magnum logo on faceplate
  • User ManualA/V Revolution Review I experienced something interesting with the Atlas Magnum. I have always heard that more powerful amplifiers are desirable even at lower listening levels and even in smaller rooms. I had never really understood that from my own experience until now. For the first time, a more powerful amp sounded more relaxed and effortless even at moderate levels. I have had powerful solid state and tube amplifiers in my system, but never really heard the benefit in my small listening room. The Rogue was kind of an eye opener in that regard. I also have no doubt the Rogue will have no trouble in bigger rooms and with more demanding speakers, within reason of course. Soundstage Review Rogue Audio started with a plan to produce an affordable push-pull tube amp of medium power with a reach into true high-end sound. The result is the Atlas, an amp I especially liked because it embodies so much of what makes tubes fun to listen to without completely abandoning the drive and honesty of solid-state designs. One could spend a whole lot more money on an amp that doesn't sound nearly as good. Accuracy and musicality are bedrocks of good audio design, and they are embedded in the Rogue Audio Atlas, which, at $1395, is a rock-"solid" success. Stereophile Review Rogue Audio's Titan Atlas Magnum offers the audio world exactly what we need exactly when we need it. As the audio crowd ages, the Atlas Magnum offers true high-performance amplification that the beginning audiophile can afford. In a world where iPods and downloaded music put convenience over sound quality, the Atlas Magnum is a tube design that will reward the owner who also wants to enjoy audio as a hobby. In an audio industry obsessed with creating the next kilobuck component, the Atlas Magnum is a beautifully built, great-sounding amp that's designed and made in the US, and it costs $1995. Go listen to a Titan Atlas Magnum. It's a product that actually does something for the 99%.
