Jadis I300 Tube Integrated Amplifier launched. In the audiophile world, there is a purist group that strives for simplicity in tube amplification systems by focusing on the use of tubes designed in the early days of tube technology: directly heated triodes, of which the most famous is the 300B.
I300 is built around a simple push-pull 300B with no feedback that offers unmatched musicality from this tube.
After pre-amplification with an ECC82, the signal feeds a phase inverter (called a Schmitt) followed by enough 6SN7 triodes to drive the 300B.
The power supply is another strong point. Besides the fact that each stage has its own power supply, special care has been taken with the 300Bs themselves.
Like direct heating triodes, the heater is the cathode. This requires a very “clean” power supply with no fewer than seven separate power circuits.
Like all our devices, the transformers are designed and manufactured in our workshop. The one dedicated to the power supply uses an EI M6X magnetic circuit with a design that provides very stable operation, no noise and low overheating.
The outputs use a double CV38 magnetic circuit built to our standards. The I300 is the only IC with such an output transformer.
A design mode that allows the device to appear much more powerful than its 10W may suggest!
In terms of design, the I300 stays true to our range and has a compact design. The 2mm thick 304L chassis easily supports the weight of other items. For greater comfort of use, it is equipped with a remote control.
Listening to the I300, it’s about the 300B’s precision, subtlety, and musicality that magnify your tracks. It will certainly delight discerning triode-loving audiophiles!
