Rogue Audio Stereo 100 Power Amplifier

Stereophile Class A "Recommended Component" – "Everything We Could Hope for in a Tube Amp"

Whether your tastes run to the delicate strains of the violin or the wail of the electric guitar, the Rogue Audio 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.

"Remember those McIntosh MC30 tube amps…? The Stereo 100's tank-like build quality, vividly neutral dynamic sound, and timeless styling make it a worthy successor to McIntosh's most adored classic," reports Herb Reichert in his review for Stereophile, which honored the Stereo 100 by awarding it Class A "Recommended Component" status. "In my view, the Stereo 100 is everything – sonically, mechanically, aesthetically – that we could hope for in a 21st-century tube amp. Everything about it screams 'End-game tube amp, long-term keeper!'"

"Earns My Highest Recommendation in Regards to Sonics and Value"

"My time with the ST-100 was one of the most musically enjoyable in recent memory," notes Andre Marc in Issue 70 of positive-feedback.com. "It earns my highest recommendation in regards to sonics and value. It is virtually maintenance free, aside from periodical tube biasing. As with all the other Rogue products I have had in house, it was 100% reliable."

"The Rogue Audio Stereo 100 power amplifier is a GREAT product. I have heard no other amp under $15,000 that has comparable levels of control, clarity and consistency of tone," reports 10audio.com in a June 6, 2018 review. " Of course I purchased the review sample. It was one of the easiest buying decisions in my seemingly endless quest for great sound."

Massive Fully Regulated Power Supply

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.

"There are five separate power supplies in the Stereo 100—all of which utilize pi filtering to reduce ripple, thus providing a very low noise floor," notes Rogue's founder, president, and chief engineer, Mark O'Brien as quoted in the Stereophile review. "Both of the Stereo 100's high-voltage supplies use large electrolytic capacitors for storage, all of which are bypassed by high-quality film capacitors. We also use very–high-quality parts throughout the Stereo 100, including aluminum/oil Mundorf coupling caps, lots of Vishay and PRP resistors, as well as Cardas hardware."

Switch Between Pure Triode and Ultra-Linear Operation

With a simple flip of a switch on the rear panel, audiophiles can choose between "pure triode" and "ultra-linear" operation to suit their tastes and power requirements. Output power is 100Wpc in Ultralinear mode and about 60Wpc in Triode. The transparency and power of the Stereo 100 is testimony to a design that truly transcends that of the competition.

The tube complement consists of four KT120, two 12AU7, and two 12AX7. A built-in bias meter simplifies checking and tweaking vacuum tube bias.

More Than Skin-Deep Beauty

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.
