Whether your tastes run to the delicate strains of the violin or the wail of the electric guitar, the Rogue Audio’s Stereo 100 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. From the Mundorf EVO Oil coupling capacitors to the custom wound output transformers, the audio signal travels through only the finest components available. With this winning combination of leading edge circuit topology, great components, and a stunning appearance, you can be certain that you are investing in an amplifier design that only Rogue Audio can deliver.
