As owners of high efficiency speakers know, finding a very high quality power amplifier can be a difficult and expensive task, and it was with this in mind when we asked Audion to develop an extremely high quality power amplifier optimised for such systems. The basic design choices were simple, it had to be a feedback free valve design using single ended topology. The 2A3 valves effortless resolution and dynamic prowess made it the obvious choice and so the Silver Note amplifier was born.

The Silver Note is completely hand made and hard wired with pure silver wire in selected parts of the audio stage. Only high quality components are used to ensure the finest sound and non ferrous (military grade aluminium) casework is used for both sonic and cosmetic reasons. A combination of 5687 and 6922 valves are used to feed the 2A3 output valve, and the design produces 4 watts per channel (6dBW).
The amplifier was designed from the outset to drive high efficiency speakers and we would recommend partnering it with designs of 93 dB sensitivity and upwards, although in some systems great results have been experienced with lower sensitivity speakers.
The Silver Note has also been designed with a very low noise floor enabling its use with extremely high sensitivity horn loudspeakers.

This amplifier is now available exclusively at Noteworthy Audio and retails for £2,500 inc vat.
