Operating in pure Class A, the single-stroke monaural amplifier with parallel lamps, using a pair of highly prized 211 triodes in each case, represents a level of performance radically superior to the vast majority of modern analogues. They use a similar scheme and topology to the legendary Audio Note (UK) Gaku-On.

More components

  • Ginrei

    Power amplifiers mono

    Audio Note Ginrei

    Audio Note Ginrei, a pair of single-stroke monoblock amplifiers with parallel output lights, operate in pure Class A and use a pair of highly valued 211 triodes per case, representing a performance level radically superior to most modern analogues.

  • Gaku-On

    Power amplifiers mono

    Audio Note Gaku-On

    The Audio Note Gaku-On amplifier is the pinnacle of our monaural amplifiers, and we did not consider any costs during their development and production. The most sophisticated components are used, including a variety of Black Gate™ capacitors, our own Audio Note (UK) silver foil capacitors and tantalum resistors, silver wire and the finest metals for all transformers, as well as silver wiring for the entire signal circuit.

  • Kassai

    Power amplifiers mono

    Audio Note Kassai

    Monoblock single-stroke amplifiers of the 4th level. Power 22 W, class A, without feedback with parallel activation of the output triodes 300B. Double C-cores made of Ultra HiB plates with copper primary and silver secondary windings, signal capacitors made of copper foil Audio Note™, 1 W tantalum resistors, Silmic and Black Gate decoupling capacitors. all internal wiring is with a silver Audio Note™ cable; a set of lamps for two Kassai monoblocks: 4x 300B, 2x NOS 6SN7, 2 x NOS 5U4GB.

  • Shinri

    Power amplifiers mono

    Audio Note Shinri

    Audio Note Shinri power amplifier. ( 1x 300B ) Level 4; 10 Watts in Class A; single-stroke, feedback-free mono power amplifiers on a single 300B output lamp. Operating in pure Class A, the single-stroke tube amplifier, which uses one 300V direct-channel triode in each channel, represents a performance level radically superior to most modern analogues. The Audio Note Shinri was specifically designed for music playback, not a technical specification, and meets the Audio Note Level 4 criteria.

  • P4 Balanced Tonmeister

    Power amplifiers mono

    Audio Note P4 Balanced Tonmeister

    The Audio Note P4 Balanced version is equipped with XLR connectors instead of RCA connectors. These connectors are connected to an extremely high-quality, Audio Note (UK)™ input transformer, providing the best possible connection for properly balanced equipment. The balancing transformers of the XLR inputs are manually wound in Audio Note (UK) with copper wire. The core material is of the highest quality, offering the best signal path from your preamplifier.
