The TA-22 has a solid reputation as a hybrid desktop amp/DAC with a lively, muscular presentation, but at £338 it sits well above the usual used range for this model. Against the recent market anchor of £240 median and £269 at the 75th percentile, this is an ambitious ask unless the condition and extras are genuinely exceptional.
That said, it’s still a worthwhile piece if you want a one-box tube-flavoured headphone setup that can do both character and drive without sounding fussy. It tends to appeal to listeners who want a bit of warmth and swing rather than clinical neutrality, so value comes from the sound and convenience as much as the badge. At this price, I’d want clear proof of excellent condition, original box, and any useful accessories to justify paying up.

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.
