Comments from Rogue
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 matchless quality of Rogue amplifiers is obvious at first glance. However, Rogue’s quality is not just skin deep. Ultra-high tolerance components, two-ounce copper circuit boards, and silver plated switches are just a few of the many features which separate Rogue products from the competition. Our amplifiers have been designed to be extremely reliable. Electronic components are rated far beyond their intended use, and only the highest quality components are incorporated into our designs. The rugged aluminum chassis are treated to resist scratching and corrosion and the machined aluminum faceplate and knobs are anodized to protect their appearance.
At Rogue Audio, we believe that a truly great performing amplifier should dress the part. And from the heavy aluminum faceplate and knobs to the gold connectors in the rear, Rogue amplifiers speak to the audiophile’s aesthetic sense. Our expressive appearance is the brainchild of world class industrial designers who have created a perfect unity of form and function. The sophisticated styling and elegant lines of our amplifiers are intended to please the upscale tastes of high-end devotees.
High-end amplifiers typically command stratospheric prices. Rogue Audio was founded on the belief that great amplifiers can be designed and manufactured at affordable prices. Rogue products provide outstanding value with performance that rivals the very best amplifiers at any price. Our amplifiers are engineered using a quality-by-design philosophy, and every one of our components is hand assembled and tested by highly skilled technicians and engineers. The confidence we have in our products is evidenced by a generous warranty that is certain to please today’s quality-conscious consumer.99 Details
Totally transparent yet rich with detail, the Rogue Ninety-Nine preamplifier sets a new benchmark in ultra high performance audio. Designed and engineered without compromise, the Ninety-Nine boasts ruler flat response, tremendous bandwidth, huge dynamic range, and vanishingly low levels of distortion. However, extraordinary test-bench specifications tell only part of the story. While tube preamplifiers are widely regarded as providing the most natural and appealing sound, the Ninety-Nine preamplifier must be auditioned in person to be fully appreciated. The smooth yet detailed sound of the Ninety-Nine can only be described as remarkable, with a presence that will bring your system to new heights of sonic performance.
From a technical standpoint, the Rogue Ninety-Nine utilizes four 6SN7 tubes configured in a mu-follower circuit topology. An analog remote volume control enhances the listening experience without compromising sonic integrity, and a logical turn on procedure protects downstream components while prolonging tube life and performance. The massive power supply includes a toroidal transformer in a separate chassis, high-speed HEXFRED diodes, seven separate regulators and a toroidal high voltage transformer. An uncompromised "leading edge" design housed in an elegant and refined package. Truly ... An Intelligent Indulgence.Stereophile Review
In competition against the Musical Fidelity Nu-Vista and VTL 5.5 preamps, the Rogue Magnum Ninety-Nine proved smooth, nimble, and muscular. The hybrid Nu-Vista (on MF's Nu-Vista 300 power amp) offered a cooler, more laid-back presentation, with exceptional lateral imaging and a brilliant, extended top end. The Rogue's soundstage extended farther behind the speakers, and, due to its wealth of midrange detail, seemed to project farther into the room as well, giving the music a palpably live, forward presence. While the Rogue wasn't as breathtakingly transparent as the Nu-Vista, it was still quite clear and open. Nor did the Ninety-Nine evince the sort of excessive bloom that makes for the softened, diffuse presentation or laggard rhythm and pacing of some tubed line stages; tight, quick, and snappy, it offered a more focused brand of midrange presence—blossom without bloat.User Manual
