Offered is „Master S 5A“ by Synergistic Research as second-hand device from the category „Mains fuses“ on audio-markt.de - the online market place for high-end. The advert with the number 3899641435 ends on 10.12.2026 at 16:05 o'clock.
At €390, this is a strong bargain. It sits well below the €620 25th-percentile mark in your 74-listing sample, and far below the €1,988 median, so the asking price looks especially attractive for a genuine Master Fuse rather than a lesser Synergistic Research variant. The exact fuse format and rating still matter, but the market position is excellent.
The Master is Synergistic Research’s flagship fuse, aimed at greater resolution, dynamics, speed, impact, and soundstage scale. A 5A rating is widely offered, but confirm whether this is the 5×20 mm or 6.3×32 mm version, and whether it is slow-blow or fast-blow before buying. At this price, with the correct fit and a clean, functional example, it is a worthwhile low-risk experiment for a revealing system.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
