Rogue Audio Stereo 100 Tube Power Amplifier

Description

MY TAKE: Established in 1996, Rogue Audio has a well-earned reputation for quality and performance. Their products have received rave reviews and awards from the audio press worldwide. We especially appreciate the fact that 100% of their products are proudly crafted right here in the USA. Excellent sound preamp. - Galen Carol

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. 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.

REVIEWS:

Stereophile: "Remember those McIntosh MC30 tube amps that were left turned on for 30 years and still sounded wonderful? Well, I doubt the new KT120 tubes in Rogue Audio's new power amplifier will last over 262,980 hours, as the G.E. GT6L6GCs in those ancient beauties did, but I'm certain that 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. 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!" - Herb Reichert

10 Audio: "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. It was a pleasure working with Mark O’Brien and Rogue Audio on this review, and I look forward to listening to music every day with this fine amplifier in my system. Of course I purchased the review sample. It was one of the easiest buying decisions in my seemingly endless quest for great sound."

Positive Feedback: "My time with the ST-100 was one of the most musically enjoyable in recent memory. At an introductory price of $2995, 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 ST-100 is almost too good to be true. 100 watts of tube power, superb sound, built like a tank, and it does not cost a fortune? Count me in. So what does the ST-100 give up? Maybe, just maybe those last few percentage points of refinement that the very best tube amps in the world offer. This is up to sophisticated listeners to decide for themselves. Personally, I would live with the ST-100 happily ever after, without hesitation." - Andre Marc
