Our Thoughts RADAR AI

This listing is a genuine bargain in the current used market for the Keces S300, as the £2,200 asking price sits far below even the 25th percentile of £435 derived from your database of four recent GBP listings. While new retail for the S300+ (the likely successor) hovers around £3,000–£3,500 depending on region, the original S300 still commands serious respect for its 130W per channel output and unique high-bias Class A mode up to 5W, delivering that warm, pure Class A feel before switching to robust Class AB for the rest of the dynamic range.

The S300 is well-regarded for its massive power supply (1200V transformer) and damping factor exceeding 1500, making it a tank-like driver for demanding speakers without sacrificing tonal richness. At this price, it’s a clear buying opportunity for anyone seeking high-end performance without the flagship cost, especially if the unit is from an original owner with accessories intact. No caveats apply here—this is a clean, well-loved product offered at a price that simply doesn’t match its typical market value, making it an excellent entry into serious hi-fi power amplification.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Keces

Keces Audio, founded in 2002 in Taiwan, emerged with a singular mission: to purge ambient noise from the signal path, delivering pure, crystalline sound akin to a live performance. Operating under Huikang Electronic Co., Ltd. in New Taipei City, the brand has quietly honed its expertise over two decades, prioritizing acoustic purity in every design.

The company's product lineup centers on high-end power solutions, including linear power supplies like the P8 dual-output model and the BP-2400 balanced isolation conditioner, which stabilize and refine electricity for optimal audio performance. Keces has expanded into amplifiers such as the S300+ stereo power amp and S4 preamplifier, alongside niche offerings like the EBRAVO HiFi streamer, all engineered for compact elegance and sonic precision rather than sprawling categories like speakers or headphones.

Positioned as a boutique player in the high-end hi-fi market, Keces earns praise for affordable yet robust components that punch above their weight in build quality and transparency. Taiwanese precision defines its reputation, appealing to discerning buyers seeking cleaner, tighter sound without extravagant pricing, though it remains somewhat niche outside dedicated audiophile circles.
