Offered is „Q-FLT Audio Filter & DC Blocker“ by Heed as new device from the category „Line Filter“ on audio-markt.de - the online market place for high-end. The advert with the number 763652431 ends on 21.10.2026 at 16:02 o'clock.
A handy little utility piece, and the asking price sits a touch above the typical used level but still in sensible territory for a clean example. With a median recent used ask of €403 and a 75th percentile at €1,269, €420 reads as fair rather than ambitious.
These filters can be a worthwhile buy when you’re cleaning up DC-related hum, transformer noise, or a system that benefits from a quieter mains presentation, especially if the rest of the chain is already sorted. The upside is mainly practical rather than flashy: if it’s complete, tidy, and working properly, this is the kind of accessory that can make a real difference without taking much space or fuss.
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.
