£600 is fair to slightly attractive for a used MS-300B if it’s complete and healthy; this is a serious 300B SET integrated, and new/retail pricing on Yaqin 300B integrateds sits far above that level. The catch is that condition matters a lot here, because £600 is only a buy if the amp has been working properly and the tubes are in decent shape.
What makes it worth chasing is the usual 300B appeal: big, vivid midrange, excellent imaging, and that effortless single-ended Class A character that makes efficient speakers come alive. This model is also relatively well-appointed for the type, with remote control and headphone functionality mentioned in owner/review material, so a clean, original-owner example with box, remote, and known-good tubes is a genuinely appealing used purchase.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Yaqin is a Chinese audio brand that appears to have been founded in 1994, with its manufacturing rooted in southern China, often associated with Foshan/Shenzhen-area production. Publicly available information suggests it began as a small family-run operation and was later built out into a more formal factory brand. The company’s exact founding story is not especially well documented in English, so details beyond the 1994 origin should be treated cautiously.
The brand is best known for vacuum-tube hi-fi components, especially integrated amplifiers, power amplifiers, tube preamps, and phono stages. Models such as the MC-10L, MC-13S, MC-84L, MC-100B, and MS-23B are frequently referenced by enthusiasts. Yaqin has also claimed broader production capabilities, including transformers and related audio electronics, though its core identity is clearly centered on tube amplification rather than loudspeakers, turntables, headphones, or cables.
In the market, Yaqin sits in the value-oriented to mid-tier tube-audio segment rather than the true high-end. Its appeal is strong among listeners who want classic valve sound, straightforward serviceability, and a relatively affordable path into tubes. It is not generally regarded as a luxury boutique marque, but it has earned a reputation for delivering decent performance for the money, especially for buyers comfortable with a more traditional, component-driven approach to hi-fi.
