Sugden A21 // New / Integrated Amplifier w/Phono / Pure Class A

Introduced in 1967, the A21 was the world's first production Class A transistor amplifier, designed by British pioneer James Sugden. His legacy shines through the remarkable Signature A21 integrated. With incredible attention to fit and finish, the Signature A21 delivers a solid tactile experience that exudes quality. This piece has clarity unmatched at this price point, with pure Class A performance that feels like twice the output it's rated for. It's bloody brilliant.
