At US$70, this Topping TP22 listing sits right at the median of the current used market, making it a fair price rather than a bargain or an overreach. Your database anchor shows a 25th percentile of US$62 and a 75th of US$70 across three recent USD listings, so US$70 is exactly where the market ceilings out for this model. While one eBay listing shows US$49.99, that appears to be an outlier or potentially incomplete sale, and another US$50 listing explicitly lacks a power supply, which invalidates it as a true comparable for a complete unit.
The TP22 is a well-regarded Class-T amplifier praised for its TK2050 chipset, delivering clean 30 watts per channel with a 20Hz–20kHz frequency response that many enthusiasts find surprisingly robust for desktop or near-field setups. If this listing includes the original power supply and any remote or cables, it represents a solid buying opportunity for anyone wanting decent power without the bulk of traditional Class-A/B amps. At a fair price with no stated condition issues, there’s no need to hedge; this is a worthwhile pick for a T-class fan looking for value.
