A respected little integrated, and £512 looks about fair for a clean used example. New pricing sits well above this, so you’re not paying silly money, though it isn’t quite a bargain-level steal unless condition and extras are especially good.
What makes it worth considering is the sound: the Obelisk Si has a lively, musical, slightly valve-like balance with real drive and timing, and it’s known for punching above its rated 50 watts. It also has useful modular options for phono or DAC duties, plus the external PSU upgrade path if you want to grow it later. At this price, I’d mainly want to know whether any cards or the power supply are included.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Heed Audio emerged from the passion of Hungarian hi-fi enthusiast Zsolt Huszti, who during the Iron Curtain era imported and tinkered with British audio gear like Ion Systems and Nytech designs. Founded in 1993 in Budapest, the brand debuted with the Obelisk integrated amplifier, its circuitry rooted in the concepts of the late Richard Hay, founder of those pioneering marques. Huszti, now owner and chief designer, named it "Heed"—the Hungarian word for bridge (híd), pronounced "heed"—reflecting its bridged output topology and ambition to connect listeners directly to music.
The company specializes in compact, high-performance amplification, including the enduring Obelisk series integrated amps, along with phono stages like the Questar and Quasar, which earned acclaim for synergy with Rega turntables. Heed also produces DACs, CD transports, speakers, and select accessories, all designed and manufactured in-house with global parts. Casework, once UK-sourced, now comes from top Hungarian metalworkers for precision and consistency.
Heed occupies a niche boutique position in the high-end market, prized by European cognoscenti for its "forget hi-fi—remember music" ethos: handcrafted gear delivering sonic purity, musicality, and engagement without ostentation. With a small team in Budapest, it commands respect for unpretentious excellence, bridging vintage-inspired circuits with modern refinement.
