At £325, this sits above the recent used median of £249 and even a touch over the 75th percentile at £313, so it reads as ambitious rather than a bargain. It’s not wildly off for a well-kept example, but the price only really works if the condition is excellent and it comes with the original packaging, tubes, and accessories.
The TA-22 is a well-liked all-in-one desktop amp/DAC with plenty of power, balanced outputs, and a pleasing hybrid presentation that suits full-size headphones especially well. It’s a solid buy for someone wanting one box to cover DAC, amp, and tube flavour, but at this level you want proof it’s been looked after and that nothing is missing.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
xDuoo is a Shenzhen, China-based audio brand that emerged from the country’s fast-growing hi-fi manufacturing ecosystem. Its exact founding year is not consistently stated in the sources available here, and no founder is prominently verified, but the company is widely presented as Shenzhen xDuoo Technology Co., Ltd., with roots in OEM/ODM production before building its own consumer-facing identity.
The brand is best known for headphone amplifiers, DAC/amp combos, portable DACs, tube hybrids, and other desktop-and-portable electronics aimed at personal audio enthusiasts. xDuoo’s lineup has included tube headphone amps, balanced amplifier designs, digital-to-analog converters, and all-in-one sources, typically positioned for headphones rather than loudspeakers or turntables.
In the market, xDuoo sits in the value-to-mid-tier audiophile segment, with a reputation for offering ambitious feature sets, lots of connectivity, and occasional tube-flavored designs at relatively accessible prices. It is not generally considered a luxury or vintage-collector brand, but rather a practical, performance-driven Chinese hi-fi maker with a strong presence among enthusiasts seeking high features per dollar.
