Description

Audion Silver Night Anniversary 2A3 hard wired
stereo is our intermediate leve lpower amplifier, using the well known
2A3. This amplifier is hand built and point to point hard wired (Air
Wired©)  avoiding the use of Chinese components where possible. This
triode based stereo amp uses no (zero) feedback in the design. The
chassis is black powder coated aluminum as is the transformer cover. The
top plate and badge are mirror finished stainless steel.

The Silver Night range of amplifiers are the best known of
the Audion products, and the ones that have won most awards, notably
amp of the year in Japan 2010. The SN 300B hard wired was the amp
originally reviewed by Sam Tellig that put Audion’s name onto the map.

Amplifier matching

This Silver Night Anniversary  is best suited for use with
loudspeakers of 97db or better efficiency. Ideally matched with our
range of Electron  cables. The amps deliver 3.5 watts into 8 ohms
from a 2A3. Upgrade options are available for this model, see upgrade
options at end. Integrated option (5 Stereo inputs is available on all
stereo models)

Quality both inside and out

Having a volume control on the front and stereo inputs on
the rear means that a pre-amplifier is not necessary with this unit,
but is advised . These amps are all auto biased. The 2A3 uses either
Sovtek or Electro Harmonix.

The Silver Night Stereo range can reproduce subtleties and
nuances in music that can not be found in other amps of this price. The
300B gives a good overall sonic performance from a well know tube, the
2A3 delivers less power and is suited for loudspeakers really over
97db efficiency, they can be used with speakers of less efficiency but
will "run out of steam" quicker. The 2A3 is a good amp to use with Horn
loudspeakers as it has an extra 2 power supply stages and is quieter
(less than 1mV noise). All of these amps are wired for 8 ohms, however
they have a 4 ohm tapping that can be changed internally.

The Silver Night Anniversary is built with components sourced from
Europe and the US. Where possible we avoid the use of any Chinese
component. Our output transformers are wound in-house to our exacting
standards and many of the components are either made by us or
specifically for us. We use JJ 300B and Russian New old stock 6H1N as a
driver and input tubes.
