Offered is „TU-666M Gerätefüsse“ by Harmonix as second-hand device from the category „Device feet“ on audio-markt.de - the online market place for high-end. The advert with the number 3166563816 ends on 25.11.2026 at 16:30 o'clock.
Timing matters a bit here because this is a discontinued, limited-edition Harmonix tuning foot, not a current model, so the appeal is mostly in condition and completeness rather than new-product comparisons. At €699, it sits comfortably below the €687–€1,315 used range’s center of gravity and well under the €952 median, so this reads as a solid buy rather than an ambitious ask.
The TU-666M is well regarded for bringing a cleaner, more controlled, more focused presentation under heavy electronics, and it was designed as a premium adjustable foot for serious gear. If the set is complete and the hardware is intact, the upside is real: these are niche, high-end accessories that don’t come up often, and a clean set at this level feels like good value for someone already chasing the last bit of mechanical tuning.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Harmonix is not a recognized brand in the hi-fi or consumer-audio sector. Extensive searches yield no verifiable information on a company by that name producing amplifiers, speakers, turntables, DACs, headphones, cables, or related equipment. The closest matches are unrelated entities: Electro-Harmonix, an American effects pedal maker founded in 1968 by Mike Matthews, focused on guitar fuzz, phasers, and delays like the Big Muff Pi; and Harmonix Music Systems, a Boston-based game studio from 1995 known for Rock Band and rhythm games, acquired by Epic Games in 2021.
Without confirmed details on origin, products, or market position for a hi-fi Harmonix, any description would rely on speculation, which cannot be provided. Knowledgeable buyers should note that obscure or boutique hi-fi brands often require direct verification from manufacturer sites or industry directories, as generic searches frequently confuse them with guitar effects or gaming firms.
If this refers to a specific Japanese cable or accessory maker sometimes called Harmonix (e.g., Harmonix Reimyo), details remain unconfirmed in available sources, positioning it as niche rather than established hi-fi. For accurate intel, consult specialist audiophile forums or retailers.
