Aug 20, 2012 · This romance concerns the stunningly anthropomorphic Jadis Eurythmie II (mostly) horn speakers and the petite, jewel-like and vivacious Jadis SE300B amps—a 10W single-ended triode design with paralleled output tubes.

The SE300B supplies a power of 10W RMS and functions in pure class-A with single-ended mounting (the two tubes are in parallel) with an automatic bias. The two high voltages, driver and power, have vacuum-tube power supplies. The bandwidth (at –3dB) is from 20Hz to 20kHz, without any feedback.

The Jadis I300 is built around a simple push-pull 300B with no feedback and 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.

Jan 18, 2023 · The Jadis I300 is a 300B integrated amplifier with the power tubes in a push-pull configuration. Stu takes a listen. I was dreading this amplifier arriving from the very moment we agreed to review it, which if I recall was way back in May of 2022.

Description: Single-ended triode monoblock amplifier: Tube complement (each): 2 x 300B, 2 x 5R4, 1 x 6SN7. Output impedance: adjustable, for 1–16 ohms. Output power at 1kHz for 0.3% THD: 10W RMS (10dBW).

I300 is built around a simple 300B push-pull without feedback which offers unequalled musiciality of this tube. After the preamplification using an ECC82, the signal feeds a phase inverter (called Schmitt) followed by 6SN7 triodes sufficient to drive the 300B.

I'd characterize this tube as extremely balanced in all sonic qualities. It's powerful and strong-sounding, without getting overboard about it, never falling crude or rough. On the contrary, it is as refined as it's possible to be. It does excellent-quality bass, evenly distributing energy from the bottom to the upper midbass.

May 6, 2021 · Nothing in common? Far from it: Jadis has a commitment to low-powered single-ended tube amps, represented here by the SE300B monoblocks (£6498 each) and partnered with the newer £8498 JPL MkII tube preamplifier, while DeVore specialises in high-sensitivity, easy-to-drive loudspeakers.

The SE300B delivers 10W RMS in pure class A with single ended mounting (the two tubes are in parallel). There is absolutly no feedback in the bandwidth @ 3dB from 20Hz to 20kHz. The driver stage, powered at 400V, is built around a double triode 6SN7 and the two elements of the tube are mounted in cascade.

Jul 7, 2022 · The new Jadis I300 completes the high-end French HiFi brand’s integrated amplifier range. The Jadis I300 is equipped with the 300B valve, much beloved by audiophiles. This tube is well known for its fine restitution of the music. The two 300B valves per channel are mounted in a push-pull configuration without feedback.
