I expected great things from this amp, and wasn’t disappointed. The Jadis produced a large and powerful sound that belied its relatively modest 50 W power output. Allied to this is a delectible smoothness and sense of refinement. Sonically, it’s the proverbial iron fist in a velvet glove. The end result is both gutsy and dynamic while at the same time subtle and delicately nuanced.

Along with massive scale and dynamics, the Jadis sounded very mellifluous with a deliciously effortless, fluid sort of musical presentation. It offers a very neutral/natural tonal quality that’s mellow and warm without being soft or lacking in focus. From all this, you might think this amp sounds euphonic, and superficially there’s an element of that. But this implies it has a character that is superimposed on each recording, and that’s definitely not the case. It’s more like the amp teases these qualities out of the recording.

Yet, for all its innate warmth and smoothness, the Jadis is not lacking in bite or immediacy. It’s actually a very fast and lithe-sounding amplifier, offering outstanding clarity and definition. Bass is quite exceptional – clean, powerful, deep – and remarkable for a transformer-coupled tube amp. The manufacture claims a frequency response of 10 Hz to 36 kHz (-3dB), which is very extended and well up to solid state standards. It suggests that the output transformers have very low losses at frequency extremes.

This amplifier is hard to beat for those who prize warmth, delicacy, subtlety, finesse, and seek assertive dynamics without aggression. It produces gorgeous results; its innate sweetness and refinement make it a joy to hear. Any foibles suddenly seem secondary to the wonderful music it makes. It’s a sound that captures the heart, as well as the mind.

Quite simply, it’s one of the best-sounding amplifiers that I have ever heard.
