Rogue Audio Stereo 100 Amplifier
Whether your tastes run to the delicate strains of the violin or the wail of the electric guitar, this power amplifier will thrill you with its precision, musicality, and impact. And with 90 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 amplifier consists of four matched KT88 output tubes operating in push-pull configuration. A massive linear 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.
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 amplifier is testimony to a design that truly transcends that of the competition.
While the build quality is readily evidenced in the exquisitely sculpted appearance, 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 of exceptional quality.

What Reviewers Are Saying
Pros
Delivers a wide, deep soundstage with precise imaging and natural vocal presentation.
Produces unusually strong, well-controlled bass for a tube amplifier, even with demanding speakers.
Offers a solidly built chassis with practical triode/ultralinear switching and easy biasing.
&
Cons
Its 60-pound chassis makes setup and repositioning physically demanding.
Triode mode trades away some output power, so maximum drive depends on the chosen operating mode.

Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
92/100
Reviewers describe the Stereo 100 as solidly built, with massive transformers, a hefty 60-pound chassis, substantial binding posts, and large meters. The rear-panel triode/ultralinear switching and the mounted biasing tool add practical engineering touches that reviewers clearly appreciated.
Value for Money
86/100
At roughly $4,995, reviewers treat it as a premium purchase rather than an obvious bargain. One review acknowledges the high-end price while still emphasizing the appeal of the performance, but there is not enough direct value praise to make it sound like a standout deal.
