Icon Audio Stereo 40 Mk IV Signature
The Icon Audio Stereo 40 Mk IV Signature is a beautifully voiced British tube amplifier that blends classic valve warmth with modern refinement and reliability. Hand-built in the UK, it uses a quartet of KT88 output tubes to deliver a sound that is rich, dynamic, and effortlessly musical. The presentation is open and inviting, with a full, textured midrange, authoritative bass, and a treble that remains smooth and extended without glare.
In its Signature form, upgraded internal components and careful tuning elevate resolution and transparency while preserving the emotional immediacy that tube lovers crave. Whether paired with efficient speakers or more demanding designs, the Stereo 40 Mk IV Signature offers a sense of scale and control that makes long listening sessions deeply rewarding. It’s the kind of amplifier that invites you to slow down, settle in, and rediscover familiar records with fresh perspective.
Remote and 4 Linlai E6SN7 tubes.
