About the Silver Night 300B

The Audion Silver Night 300B is a highly regarded single-ended triode tube amplifier featuring hand-wired construction and zero feedback design. It delivers approximately 8.2 watts per channel in pure Class A operation into 8 ohms, with a frequency response of 8 Hz to 32 kHz ±3 dB. The amplifier uses 2 x 300B output tubes, 1 x 6H23N, and 1 x 5687 driver tubes (the 5687 driver section is exclusive to the USA model for fuller sound and better impact). It is auto-biased and designed for loudspeakers with 92 dB or higher efficiency. The chassis is made of military-grade aluminum with a black powder-coated finish and mirror-polished stainless steel top plate and badge. The amplifier includes a front volume control and rear stereo inputs, eliminating the need for a separate preamplifier. It consumes about 152 watts and weighs approximately 31 lbs. The design emphasizes musical subtleties, dynamics, and strong bass capabilities, with no feedback to preserve linearity and sound purity. The amplifier has won awards including Amp of the Year in Japan (2010) and is praised for its sound quality and build craftsmanship.
