View at Jadis Electronics

Based on the same general design as the JA80, this masterpiece of equipment offers the same sound quality with an unbelievable capability to drive the most difficult existing loads.

Capable of 160 watts per channel in pure Class A and 200W with the KT150, its unique power capability and dynamic behaviour are combined for the first time in vacuum-tube amplifier history, with the ultra low distortion and transparency of the best low-power exotic Class A designs.

Its low frequency performance is unequalled. Built with the same standard as the now famous JA80, the JA200 shares its sound consistency and unmatched reliability year after year.

The output stage of the JA200 uses 10 KT88 on each mono amp. For thermal dissipation reasons, the JA200 is built on four chassis : two amplifiers and two power supplies. Each chassis is the size of a JA80 mono amp.

The JA200 will take you where very few have gone before; 160 watts of pure class A power. This four box set of ultimate musicality features two mono-block amplifiers each with its own separate power supply. Probably the last amp you'll ever buy...

Jadis JA200 MkII

The Jadis JA200 MkII is a 160 W pure Class-A monoblock that prioritizes timbral naturalness and musical engagement. Reviewers at Audiophilepure praised its lush midrange and the way voices and brass are rendered with warmth and body, while the low end remains controlled and authoritative. The large tube complement and heavy monoblock construction underpin ample headroom, resolving dynamics and transient drive with finesse. Imaging is precise with excellent timbral fidelity, though one reviewer noted a small shortfall in the very last degree of spaciousness. Built like a statement component, the JA200 MkII suits listeners chasing organic tonal balance, vocal presence and an analogue tube character—an appealing flagship for systems that favor musicality and substance.

Audiophilepure

"sounded extremely natural—gorgeous, really."

Pros

Exceptionally natural, musically engaging midrange and vocal presentation documented by listening tests.
Rich, well-bodied timbral rendering of brass and instruments, delivering pleasing tonal color and presence.

Cons

Slightly limited ultimate spaciousness compared with the very best imaging leaders.

Sound Quality

90/100

Dynamics

90/100

This is a pure Class-A monoblock rated at 160 W with heavy consumption (500 VA/channel) and a very large tube complement (20 power tubes), which strongly suggests substantial headroom and robust current delivery. Review excerpts describe natural, controlled presentation with no mention of strain or loss of control; combined with the monoblock topology this supports a high dynamics score. No reviewer explicitly called it 'reference' for slam, so score stays high but not at the absolute top.

Soundstage Imaging

89/100

Imaging and timbral accuracy are praised (the trumpet's timbre is cited positively), but the reviewer notes 'the last iota of spaciousness was absent,' indicating slightly less extreme sense of air/expansion than the very best. Channel separation and imaging are otherwise very good, so score is high but acknowledges the small loss in ultimate spaciousness.

Build Quality

92/100

Specifications and design point to substantial build quality: heavy monoblock chassis (580 x 260 x 240 each block, 130 kg), large tube array (20 power tubes) and significant per-channel consumption imply a very large power supply, robust transformers and ampere-capable construction. The monoblock layout and visible industrial heft support a top-tier mechanical and electrical implementation; no thermal or reliability issues were mentioned in the review.

Value for Money

86/100

The review title lists price as $33,900/pair (≈$16,950 per monoblock) while offering 160 W pure Class-A tube monoblocks — clearly a high-end, premium offering. The reviewer provided strong praise for sound but offered no explicit comment on price or value versus peers, so following the guidance this is scored at a neutral-to-positive baseline for its segment rather than a strong value call.
