This US$330 asking price for the used xDuoo TA-22 is fair, sitting just US$3 above the median of US$327 from four recent comparable listings and well within the typical range of US$311 to US$347. It is neither a bargain nor ambitious, representing a standard market value for this model in unknown condition.
The TA-22 remains a well-regarded all-in-one desktop unit because it combines dual ES9038Q2M DACs with two 12AU7 tubes for a hybrid tube-buffered sound, while offering USB, coax, optical, balanced inputs, and Bluetooth 5.1 with LDAC. It delivers substantial power up to 3,000 mW at 32Ω via balanced outputs, making it versatile for driving diverse headphones. At this fair price, it’s a solid buying opportunity for enthusiasts wanting tube warmth without sacrificing modern DAC performance or connectivity.

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.
