Against a new amp at this sort of money, this looks fair rather than cheap: the asking price is right on the £280 median for the three recent comparable GBP listings, well above the £244 lower quartile and below the £399 upper quartile. In other words, it’s priced in the middle of the current used market, so there’s no obvious bargain premium and no real overreach either.
That makes it a sensible buy if you want a compact, characterful amp without chasing a discount. The upside here is straightforward: if it’s genuinely clean and fully working, you’re paying market rate for a model that should be attractive to players who want a natural, responsive feel rather than a sterile practice box. At this price, I’d mainly want to confirm condition, originality, and whether any footswitch or accessories are included, but there’s nothing in the number alone that would put me off.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Sonnet Digital Audio is a Dutch high-end audio brand founded by Cees Ruijtenberg, who came to the company after a long background in digital audio engineering and also had ties to Metrum Acoustics. Its present-day identity appears to have emerged around 2019, when Ruijtenberg launched Sonnet Digital Audio after the buy-out of Metrum’s DAC business.
The brand is best known for digital-to-analog converters and related digital hardware, especially its R2R and non-oversampling DAC designs such as the Morpheus and Pasithea. It also offers matching digital components and modules, but it is not known as a maker of speakers, turntables, headphones, or cables in the way broader hi-fi brands are.
In the market, Sonnet Digital Audio sits firmly in the boutique high-end segment. Its products are positioned as specialist, audiophile-focused converters built in the Netherlands, with pricing and distribution that place them above mass-market gear and aimed at buyers who prioritize technical refinement, low-volume craftsmanship, and a distinctive house sound.
