Black Shadow 845

About the Black Shadow 845

The Audion Black Shadow 845 is a meticulously hand-built, hard-wired mono-block amplifier using the powerful 845 output valve in a single-ended triode configuration. It delivers 25 watts of Class A power into 8 ohms with no negative feedback, ensuring a natural, uncoloured sound with exceptional grip, dynamics, and realism. The amplifier features a simple circuit with an E182CC line driver, a 6922/6H23N pre-amp input tube, and the 845 power tube. It includes an additional buffer stage and improved mains and output transformers for enhanced performance. The chassis is made from aluminum, and the valves run hot, requiring careful placement. The amplifier has a variable sensitivity input, low distortion (<0.1%), and a frequency response of 13Hz to 34kHz ±3dB. It is suitable for speakers with nominal 4 and 8 ohm loads and is known for its exceptional low-frequency tonality and fluid transient response. The Black Shadow 845 can be upgraded with higher-grade components and silver wiring for improved sound quality. It is recommended to use a pre-amplifier, although the amp has a volume control and can operate with a single line-level source. The amplifier consumes 240 watts and weighs 12 kg per channel.
