For a long time now , we’ve been thinking about developing a new reference

mixing compact design and increased performances…and KT170 tube comes,

giving the starting signal of I-70 project.

This integrated is not only designed in the pure tradition with point to point wiring

and hand made transformer it’s the first to integrate several features from Jadis mono- block technology

From power supply point of view, power stage has a full separated supply makes it totally independent. Driver and power stage separated means a power stage not influenced by the other one, so 100 available. Stabilized filament voltage eliminating inducted noise.

Huge power transformer has been designed to bring dynamic and pulse power. Due to its fully new designed output transformer I-70 works in a single push-pull ultra linear with triple load configuration and then equipped with two KT170 per channel.

KT170 is a powerful tube but we prefer to take advantage of its feature to reduce distortion instead of simply focusing on its power, by choosing a functioning point different than usual.

LISTENING

I-70 is rich in sensation and full of emotions. Each register shows details, accuracy and depth. This integrated will move you by its shimmering tones and structured soundstage.

Jadis I70 — potent, musical Class A integrated

The Jadis I70 channels classic French valve craft into a 50W Class A integrated that prioritises musical engagement. Reviewers such as Alan Sircom, James Michael Hughes and Audiophilepure praise its combination of slam, speed and tonal refinement. The I70 delivers a fast, resolving and highly musical sound with exceptional imaging and a large, holographic soundstage, while bass weight and transient control belie its modest power. Build quality is superb — point-to-point wiring, hand‑wound transformers and a hefty chrome chassis — making it as much a statement piece as a performer. Ideal for listeners with efficient speakers who want a single-box, high-end tube experience. Limited modern connectivity and a hot, heavy footprint temper its universal appeal, but the sonic payoff justifies consideration.

Audiophilepure

"This is quite simply one of the best sounding amplifiers I have ever heard."

hi-fi+

"It doesn’t fall into that warm and softly spoken sound we associate with valve amps and it doesn’t sound slow, stentorian and statesman-like; it’s fast, resolving and most of all fun."

StereoNET United Kingdom

"Sonically, it's the proverbial iron fist in a velvet glove."

Pros

Exceptionally musical, natural tonal balance with immersive imaging and a large, holographic soundstage.
Surprising dynamics and bass control for a 50W Class A tube amp—fast transient attack, slam and authoritative low end.
First-rate build and finish: point-to-point wiring, hand‑wound transformers and premium chrome/gold hardware lend durability and presence.
A fast, resolving presentation that avoids clichéd ‘soft’ tube coloration—engaging, detailed and musically involving.

Cons

Deliberately limited connectivity—no built‑in DAC, phono stage or balanced inputs, which reduces versatility in modern systems.
Runs very hot and is physically heavy; high power consumption and a tube cage that traps heat may matter in smaller rooms.
High input gain and modest nominal power mean it pairs best with efficient speakers; volume control range can feel compressed with very hot sources.

Dynamics

92/100

Despite being a 50W Class A tube design, reviewers describe the I70 as gutsy, dynamic and fast — delivering impressive slam, control and headroom for its topology. Comments such as 'gutsy and dynamic', 'effortless, fluid' and 'weight and power of the lower frequencies' support strong dynamics relative to its Class A expectations.

Soundstage Imaging

94/100

Reviews repeatedly reference superb imaging, a large powerful soundstage and an uncanny sense of 'living souls' appearing in front of the listener. Phrases like 'sense of rightness about imaging' and the apparent scale that belies 50W point to excellent channel focus, depth and convincing holographic presentation.

Build Quality

95/100

Build is described as extremely well made with point-to-point wiring, hand-wound transformers, heavy chassis and high-quality finishes (chrome stainless steel, gold-plated fixtures). Reviewers note high-end component selection and construction consistent with the price and brand pedigree.

Features Connectivity

83/100

Feature set is deliberately traditional: five unbalanced RCA line inputs, one throughput/bypass for recording/HT, two sets of speaker terminals (bi-wiring), and a remote. There is no built-in DAC, no phono stage and no balanced inputs, so connectivity is limited compared with modern all-in-one integrateds.

Value for Money

90/100

At roughly £11k+, reviewers acknowledge it is expensive but consistently say 'you get what you pay for' and indicate the sonic and build pedigree justify the price for buyers in this segment. Limited facilities are noted, but value sentiment is that the performance and craftsmanship make the price understandable.
