So, timing is another particular strength; the late, and much missed Jacques Loussier’s ‘Pastorale’ from Plays Bach[Telarc] has lots of subtle inner detail and little delights – the interplay between the piano and the percussion with its peculiar ‘not quite off-beat’ counterpoint, or the way piano and bass work together and, in particular the melodic and tuneful nature of the acoustic bass. Marc Cohn’s ‘Ghost Train’ from Marc Cohn [Atlantic] showed off its inner detail and rhythmic structure, the tom toms and tambourine being particularly tactile and texturally rich; but it’s subtly done, not pushed into your face, and all the more effective for it.

The Sugden Masterclass ANV-50 is, by any standards, a remarkable achievement. As a spiritual, if not literal successor to the pioneering A21, the amp that made Sugden’s name, it has some big shoes to fill. On this experience, it does so magnificently. It is light on its feet, and has a deftness that eludes so many otherwise decent amplifiers. Coupled with a perfectly respectable and usable power output, and the reserves to double that output into difficult loads, it’s going to be quite a challenge to find anything at the price that will give you anything like the musical satisfaction and sheer joy this amplifier delivers. Here’s to the next fifty years.
