Description :
Beneath the glossy, polished exterior of the Jadis Defy 7 mk3 lies an object of mystery and wonder. Though apparently a simple, traditional tube design, some oddly modern, solid-state details have been bolted on to the undercarriage of this ostensibly all-glass amplifier. However, there are no solid-state devices anywhere in the signal path.
The Jadis Defy 7 mk3 conveyed authority and massive reserves of power, a rare occurrence among tube amplifiers. When called upon to deliver them, it performed without a trace of indecision, strain, unmusical hardening, or concomitant shifts in tonal balance. Low-level detail was also very good, the high clarity preserved over the whole dynamic range. It has an almost complete lack of enharmonic coloration and an absence of the usual "amplifier" hardness, compression, and tonal thinning. The Jadis Defy 7 mk3 sounded rich and sweet, but naturally so, with no attendant loss of transients, or of speed or sparkle in the treble. Its wealth of sonic beauty, openness, air, and power are matched by a frequency extension and sense of control often absent from tube gear was not wholly perfect, it demonstrated detectable deviations from neutrality at several points.
The Jadis Defy 7 mk3 sense of natural rhythm and excitement was also strongly conveyed with all kinds of music. It sets the highest standards for transparency. Ally this with the very good stereo focus and excellent stage width, and there will be a glorious soundstage, spacious, open, and detailed; one which contains a wealth of perspective information. Dynamics were expressive in a natural sense, and made many solid-state amplifiers sound somewhat obstructed and compressed by comparison. The Jadis Defy 7 mk3 is a mature end-product of the Jadis design philosophy, one which attains a powerful balance of tolerant matching, pure fidelity, outright performance, and effective price.
