ONGAKU Kensei Stereo Power Amplifier

No stereo power amplifier has ever produced the levels of musical purity delivered by the Audio Note ONGAKU Kensei… It is without doubt the finest possible stereo chassis power amplifier available today.

Product details

The ONGAKU integrated has rightly earned a place in history; its name is synonymous with the finest possible audio reproduction, and for once the reality is equal to the legend!

The ONGAKU Kensei shares the same circuit as its integrated sibling, but instead is equipped with a single pair of Balanced / XLR inputs. Each input is connected to an in-house custom designed and manufactured, fully silver wired, balanced input transformer, offering the perfect input interface for any of our Balanced output equipped preamplifiers.

It is a Pure Class A Singled Ended valve amplifier that uses the highly regarded VT-4C / 211 triode valve, producing a level of performance that is radically superior to any other current designs.

Only the finest possible components have been employed: –

    • Audio Note (UK) Silver wire has been use exclusively for all internal wiring, including all transformers and power supply connections.
    • Audio Note 2 watt Tantalum resistors have been used throughout. All capacitors are either Black Gate Electrolytic or Audio Note (UK) silver foil.

All transformers are our own in-house custom designed and manufactured devices; driver and output transformers are fully silver wired AN-Perma 50 nickel C-core and the mains transformer is a fully silver wired HiB double C core.

It has been specifically engineered for sonic performance rather than technical specification, and fulfils all Audio Note (UK) Level 5 criteria: –

    • Pure Class A operation
    • Zero Negative Feedback
    • Single Ended Output Stage
    • Valve Rectification
    • Directly Heated Triode operation
    • Materials and component quality
