Sugden Audio A21SE
Integrated amplifier
The special edition Sugden Audio A21SE integrated amplifier builds on the strengths of the classic A21.
Offering pure class A single ended voltage rail operation, the sound remains distinctively ‘Sugden’.
Upgraded with a fifty percent larger power supply and increased power output, dynamics are even more impressive.
A sophisticated pre-amplifier stage is another improvement on the A21.
This provides greater clarity without added brightness producing crystal clear highs.
The larger power supply provides greater control over a wider range of loudspeakers and improved micro dynamics for low level listening.

A21 Pure Class A
The A21 was the worlds’ first production pure class A transistor amplifier and a great success.
The partnership with Richard Allan was short lived and within a year the amplifier was renamed the SUGDEN A21. Shortly afterwards, manufacturing was moved to larger premises in Cleckheaton, West Yorkshire
Present day
Today they still manufacture in the same tradition with each Sugden product being handmade by a single highly skilled team member.

We operate our own custom engineering shop , screen printing and assembly room.
