Exceptional speed, dynamic range and detail create an involving, musically natural presentation across genres.
Deep, powerful and controlled bass combines with smooth, focused tonal refinement.
Impeccable, luxury-grade construction with point-to-point wiring and hand-wound transformers.
Cons
Runs very hot and draws substantial power due to its pure Class-A valve design.
Analogue-only facilities omit a DAC, phono stage and balanced XLR inputs.
Its substantial weight makes installation a two-person job.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 96/100
Reviewers describe an unusually complete valve-amplifier performance: highly detailed and natural, yet forceful, fast and emotionally engaging. The I70 is repeatedly praised for its scale, precise imaging, deep controlled bass and ability to stay nuanced across everything from small-scale acoustic music to demanding rock and electronic recordings.
Transparency Resolution
96/100
HiFi Pig heard abundant detail, small musical nuances and convincing layers even at high volume, while hi-fi+ calls its detail and articulation superb. StereoNET similarly found outstanding clarity and definition, with a presentation that remains delicate and nuanced rather than merely analytical.
Tonal Balance Musicality
95/100
StereoNET describes a neutral, natural balance that is mellow and warm without becoming soft or unfocused, alongside rich piano tone and sweet but crisp upper registers. hi-fi+ found it deeply involving and insightful, while HiFi Pig noted a natural vocal presentation and a vivid, fresh character.
Dynamics
97/100
Dynamics are a major strength. HiFi Pig calls it as dynamic as any amplifier the reviewer has used, praising its immediate reaction to musical demands, while hi-fi+ highlights outstanding speed, energy and dynamic range across widely differing genres. StereoNET also found it gutsy, fast and powerful-sounding well beyond what its 50W rating might suggest.
Soundstage Imaging
95/100
HiFi Pig heard sharply located instruments, with performers clearly separated left-to-right and front-to-back. hi-fi+ reports superb soundstaging and imaging that makes performers seem present in the room, and StereoNET notes a large-scale, powerful presentation.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
95/100
The I70 receives emphatic construction praise from all relevant reviewers. HiFi Pig calls it impeccably put together, while hi-fi+ highlights its point-to-point circuitry, chrome-finish stainless chassis and gold-plated hardware; StereoNET also praises the high-quality components, hand-wound transformers and carefully managed internal design.
Features Connectivity
87/100
This is an analogue-focused integrated amplifier with five RCA line inputs, a record/home-cinema throughput connection, two sets of speaker terminals, balance control and remote operation. It lacks balanced inputs, a DAC and a phono stage, so listeners wanting digital, vinyl or XLR connectivity will need external components.
Value for Money
88/100
At approximately £11,498/$12,600, the I70 is unquestionably a costly specialist amplifier with limited built-in facilities compared with many modern rivals. Even so, HiFi Pig considers its performance good value at the asking price, and StereoNET's view is that its sound and construction deliver the quality expected of the investment.

Manufacturer's Description — Jadis Electronics
The emotion of tube sound, signed by Jadis
For a long time, we had been thinking about developing a new reference that would combine compact design with increased performance. Then the KT170 tube arrived, giving the starting signal for the I-70 project.
This integrated amplifier is not only designed in the pure Jadis tradition, with point-to-point wiring and handmade transformers, but it is also the first to incorporate several features derived from Jadis monoblock technology.
From the power supply point of view, the power stage has a fully separate supply, making it totally independent. With the driver and power stages separated, one power stage is not influenced by the other, ensuring 100% available performance. The stabilized filament voltage also eliminates induced noise.
A huge power transformer has been designed to deliver dynamics and pulse power. Thanks to its completely new output transformer design, the I-70 operates in a single push-pull ultra-linear configuration with triple-load output, and is equipped with two KT170 tubes per channel.
The KT170 is a powerful tube, but we preferred to take advantage of its characteristics to reduce distortion rather than simply focusing on power. For that reason, we chose a different operating point than usual.
