At £395, this Topping A90 Discrete is a strong deal, sitting well below the typical used market where comparable listings start around £495 and often reach £630 for new units. Based on the US retail of $599 (roughly £475–£500 at current rates), the standard used resale of about half retail would land near £240–£250, but well-kept examples in the UK currently trade closer to £450–£500, making this £395 ask an excellent value for a discrete, fully balanced amp with preamp function.
The A90 Discrete is highly regarded for its fully discrete circuitry, R2R implementation, and 9.8W per channel output into balanced loads, delivering clean, high-current drive that rivals far more expensive gear. It handles both headphones and stereo speakers with authority, includes a remote, and offers XLR/4.4mm/6.35mm outputs. At this price, unless the condition is questionable or accessories are missing, it’s a smart buy for anyone seeking top-tier performance without the premium-brand markup.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
