The English Acoustics Stereo 21c is a modern day classic. Exclusively British-made and notably benefiting from the finest transformers along with a chassis that are both designed and manufactured in England.

Inspired by our favorite vintage amplifiers, the Stereo 21c moves forward with it’s contemporary design cues and safety devices fitted throughout. This means you can enjoy the warm sound that the ‘21c produces whilst feeling reassured that any potential risk has been considered and minimized.

Certain aspects of the revered inner workings have now been enhanced using our own mains and audio transformer design. This means that the amplifier runs cooler and produces exceptional low-end performance. Plus, smoother roll-off at the top-end whilst retaining the classic punchy mid-range.


What sets the English Acoustics Stereo 21c apart is that you can now have one hand-built for you in any color you wish; the only limit is your imagination. To combat this personal decision, we have produced twelve in-house colors covering the full spectrum to help you set the tone. These colors have been affectionately devised from our own local landmarks, such as Lansdowne Gold, Marlborough Red, Avebury Grey and Brunel Blue to name but a few.
