Description
Jadis I88 Integrated Tube Amplifier
90 Watts of Pure Class A Power from a Double Push-Pull of KT150
The Jadis I88 is a 90-watt pure Class A integrated tube amplifier of extraordinary ambition, built around a double push-pull configuration of eight KT150 output tubes to deliver a level of Class A power that is virtually unmatched in any integrated amplifier design. The KT150 is one of the most capable and sonically distinguished output tubes available in contemporary valve manufacturing, and in the I88, Jadis deploys eight of them in a fully symmetrical double push-pull arrangement that delivers the headroom, dynamic authority, and tonal richness of 90 pure Class A watts with a composure and effortlessness that only an amplifier of this scale and engineering depth can achieve. Remote control and a USB digital input for direct computer connection are included as standard, bringing the full breadth of modern listening convenience to an amplifier rooted in the finest traditions of tube amplification.
A Double Push-Pull Architecture of Exceptional Power
Where most Class A tube integrated amplifiers deliver between 25 and 50 watts per channel, the I88’s double push-pull KT150 configuration pushes this boundary to 90 watts, entering a domain of pure Class A power that allows it to drive virtually any loudspeaker load with complete authority and without ever departing the linear region of the output tubes’ operating characteristics. The KT150 is inherently demanding in terms of the transformer design required to exploit its full potential, and Jadis’ proprietary output transformers, designed, wound, and built by hand in-house as always, have been specifically engineered to match the I88’s double push-pull topology for maximum linearity, bandwidth, and tonal purity. The result is an amplifier that brings the harmonic richness, natural decay, and three-dimensional imaging of pure Class A tube amplification to loudspeakers and listening rooms that lesser amplifiers cannot fully energise.
Modern Connectivity in a Classic Architecture
The I88 provides four line-level analogue inputs and a USB digital input for direct connection to a computer, allowing high-quality digital audio playback without the need for a separate DAC. Dual speaker output terminals support bi-wiring configurations for compatible loudspeakers, and automatic bias management ensures the eight KT150 output tubes operate at their optimal point throughout their service life without manual adjustment. An input sensitivity of 190mV and a bandwidth of 10Hz to 19kHz complete the specification of an amplifier that, at 40kg and 500 x 400 x 220mm, reflects the substantial transformer iron and chassis engineering required to sustain 90 watts of pure Class A power with the stability and musical authority that the Jadis reputation demands.
