Audion Silver Night DUO switchable 300B/2A3 power amplifier.

Audion Silver Night Anniversary DUO 300B/2A3 switchable hard wired stereo or stereo integrated power amplifier is from our intermediate level range which uses the well known 300B tubes or  switchable to 2A3. These amplifiers are hand built and point to point hard wired (Air Wired©).

This Silver Night Anniversary DUO is different from other amplifiers as the user can switch between any 300B or any type 2A3 valve, obviously more careful choice of speaker is needed. Loudspeakers of 89db or better efficiency for 300B mode 95 db or better for the 2A3. Both stereo and stereo integrateds deliver 7 watts into 8 ohms from a 300B and 3.5 watts from a  2A3. Switching is simply done at the rear by swapping fuse positions and the heater voltages are self sensing within the amp. Valve/Tube rolling is easy as the amp is auto biased.

Upgrade options are available for this model, see upgrade options in tabs below.

The Silver Night DUO 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, also Electro Harmonix 2A3 Russian New old stock 6H23N as a driver and input tubes.

The Audion Sterling EL34 Anniversary Edition is a warm and dimensional-sounding amplifier with a potent lower midrange that does justice to the power range of an orchestra. It sang right out of the box and never misbehaved. Kudos to the Audion team for breathing new life into the venerable EL34 pentode. In my estimation, the Sterling EL34 represents a gift to music lovers everywhere. Highly recommended.

"Very round, smooth and toasty," but "well capable of enough resolution to easily distinguish Red Book CDs from their SACD cousins"; the midrange is "smooth and luxurious," but the bass has "neither the detailed control nor the slam of any solid-state integrated in [the Sterling Stereo EL34's] price range" -- no surprise., pulvinar dapibus leo. "Fully capable of refined tube splendor that's unanticipated at its price level."

The sound was a contrast, detailed and extremely musical. There was no slowness and desire to lull the listener, for which I dislike for a directly heated triode single end.

Every Sterling feels like it's punching well above its weight. So Good I bought one myself. More seasoned audiophiles will know that good amplification – no matter the topology – has no sound of its own. Don’t expect the thick syrup or golden hues of sub-$1000 Chinese units. There is no sickly/heavy sauce here. Neither is there porridge bass. Who said tubes are no hopeless below the waist? (Fools!) This Audion is the healthiest of extra virgin olive oil: light, transparent, clean. And fast. It is unburdened by ponderous, labouring low frequencies or musical weight gain. Its talents lie in 1. the ability to drive a wide range of loudspeakers and 2. the beautification of music. Each combination a winner.
