At £415 GBP, this Topping A90 listing sits above the 75th percentile (£396 GBP) of recent UK used asking prices, making it an ambitious offer compared to the median of £261 GBP. While the new “Like New” version is sometimes seen around $409 USD (roughly £325 GBP) and the regular new price is $499.99 USD (~£395 GBP), the used market here clearly favors lower values, so buyers should expect to negotiate or wait for a listing closer to the £261 GBP median.
The A90 remains a highly regarded desktop amp for its world-class noise performance (0.2µVrms), ultra-low THD (0.0006%), and 7.6W output into 32Ω, making it a “giant killer” that rivals far more expensive units like the Benchmark HPA4 in measured performance. It also functions as a clean preamp with balanced XLR and 4.4mm outputs, offering real versatility. If this unit is in original-owner condition with the remote and cables intact, it’s still a solid buy—but only if the price moves toward the £300–£320 GBP range to reflect fair used value.
