What else to know about the ST-100?

Whether your tastes run to the delicate strains of the violin or the wail of the electric guitar, the Rogue Stereo 100 power amplifier will thrill you with its precision, musicality, and impact. And with 100 watts of pure tube power, you can be sure that your amplifier won’t run out of steam before the musicians do. The heart of the Stereo 100 consists of four matched KT120 output tubes operating in push-pull configuration. A massive fully regulated power supply ensures that low frequency information will not go unheard, and that the power and attack of transient musical passages will be recreated in full. And with a simple flip of a switch, audiophiles can choose between "pure triode" and "ultra-linear" operation to suit their tastes and power requirements. The transparency and power of the Stereo 100 is testimony to a design that truly transcends that of the competition.\ \ While the build quality is readily evidenced in the exquisitely sculpted appearance of the Stereo 100, the beauty of this amplifier is more than just skin deep.

Brief History of Rogue Audio

Rogue Audio 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 the 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. The amplifiers have also been designed to be extremely reliable. Electronic components are rated far beyond their intended use, and only the highest quality components are incorporated into the designs. The rugged chassis are treated to resist scratching and corrosion and the machined aluminum faceplates are anodized to protect their appearance.
