Stereo 21c

Introducing the English Acoustics Stereo 21c, a Modern-Day Classic. Handcrafted in Britain, this exceptional amplifier showcases the finest transformers and a locally designed and manufactured chassis.

Drawing inspiration from beloved vintage models, the Stereo 21c embraces contemporary design cues and incorporates essential safety features. Immerse yourself in the warm and captivating sound it delivers, with the reassurance of meticulous risk mitigation.

To enhance its performance, we have further refined the internal workings, developing our own mains and audio transformer design. This results in improved cooling, exceptional low-end performance, and a smoother roll-off at the top-end, while preserving the classic punchy mid-range.


What truly sets the English Acoustics Stereo 21c apart is its customizability. We offer hand-built amplifiers in a vast array of colors, limited only by your imagination. To guide your choice, we curated twelve in-house colors inspired by local landmarks, including Lansdowne Gold, Marlborough Red, Avebury Grey, and Brunel Blue, among others. Set the perfect tone with a personalized touch.
