What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 94/100
Review coverage describes an unusually pure, natural and tonally truthful tube presentation, with neither added warmth nor artificial excitement. It combines that musical ease with controlled bass, convincing dynamic authority and a notably expansive, precisely focused soundstage.
Transparency Resolution
94/100
Ric Mancuso calls the presentation pure and impartial, saying the amplifier adds neither exaggeration nor subtraction. Vocals were reported as intelligible, natural and free of grit or grain, while the stage was described as highly transparent.
Tonal Balance Musicality
93/100
The Stereo 100 Dark is praised for truthful tone, pitch and expression, with a natural ease that lets the music rather than the amplifier command attention. High frequencies have some sweetness, but the reviewer specifically found it neither overly tubey nor syrupy.
Dynamics
94/100
The amplifier reportedly powered Magnepan LRS speakers effortlessly from its 4-ohm taps, with ample control and dynamics. Bass was characterized as deep, well controlled and among the best the reviewer had heard from a tube amplifier, with its robust power supply credited for the stable presentation.
Soundstage Imaging
96/100
The review reports a wide, deep and full-bodied stage with precisely defined images extending beyond the speakers when recordings allowed. Vocals could lock dead center even with speakers placed nine feet apart, and were described as exceptionally lifelike and emotionally involving.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
91/100
Reviewers describe a solidly built 60-pound amplifier with massive, heavy transformers, substantial binding posts and easily read bias meters. The chassis-mounted biasing tool is a practical touch, while balanced connections and selectable Ultralinear or triode operation add useful flexibility.
Value for Money
85/100
The reviewed Stereo 100 Dark was priced at $4,995, placing it firmly in premium tube-amplifier territory. The review speaks positively about the possibility of high-end products delivering strong value, but offers little direct comparison with similarly priced power amplifiers or a clear value verdict on this model.

Manufacturer's Description — Rogue Audio
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.
