The M20 is a tiny budget-class amp, so £35 is actually quite sensible rather than flashy. Recent used examples cluster around the mid-£30s to mid-£50s, with one UK listing at £55.99 and older community references putting them around £10–£36 depending on condition and seller context, so £35 lands in fair-to-good territory for a working unit.
What makes it worth a look is simple: for pocket money, it can be a neat little switch-on-and-listen amp for modest bookshelf speakers, and the compact metal case has some appeal in a secondary system. At this price, the main thing to verify is that it powers up cleanly and that the PSU is included and stable; on these inexpensive class-D-style units, the supply matters as much as the box itself.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Muse Audio is an obscure name in hi-fi, and the clearest match appears to be Muse HiFi, a young audio brand that emerged in 2022 and is associated with China rather than a long-standing Western hi-fi heritage. Its background reads more like a modern specialist start-up than a legacy marque, and no widely established founder story is consistently documented.
Its product focus is tightly centered on personal audio: portable DAC/amps, headphone amplifiers, and IEMs, with a strong emphasis on compact, feature-rich designs and tube/transistor hybrid styling. It is not known as a maker of traditional full-size hi-fi staples like floorstanding speakers, turntables, or mainstream home amplifiers.
In market terms, Muse HiFi sits in the affordable-to-mid-tier niche rather than true high-end. The brand seems aimed at enthusiasts who want distinctive engineering and bold industrial design at accessible prices, making it more of a value-driven boutique competitor than an established audiophile heavyweight.
