Condition is unknown, but at £350 this is well above the recent GBP market for this piece: the median is £125, with the 75th percentile at £163, so the asking price is ambitious and hard to justify on price alone. Even allowing for a clean unit, it’s roughly double the top end of the usual used range, so this only makes sense if the seller can show exceptional provenance or extras.
What keeps it interesting is the A300’s reputation as a compact, modern Class D stereo power amp with plenty of clean drive for the money. It’s a straightforward, low-fuss buy when priced sensibly, but at this level a buyer should want strong evidence of condition, complete accessories, and a very good return policy before paying up.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
