The Sugden Audio A21I Signature integrated amplifier design provides affordable high-end performance from a beautifully engineered single box integrated amplifier.  Compact in size with a simple but stylish design, the A21I is possibly the only amplifier you will ever need. With many of the original A21’s still in daily use after fifty years, it could also last a life time. Providing a large soundstage and depth to all types of music, the A21 is an integrated amplifier you can listen to for hours without fatigue.  The single ended voltage rail circuit provides impressive dynamics and incredible bass.

The A21 Signature integrated amplifier is available with or without a MM/MC phono input. Without a phono input it is designated the A21L (line input only). A21aL models can be fitted with a phono input at a later date.
