Legendary mat, Oyaide MJ12 bundled with butyl mat BR-One available for sale. Both in very good condition. The MJ12 is incredibly rare on the used market and Ill probably regret selling! Any questions please ask. Payment by bank transfer. I also have the STB-MS weight available separately. Many thanks
In good condition, £350 looks fair-to-strong rather than cheap: the MJ-12 was positioned as a premium accessory, with old references putting it around £230 at launch and recent used comping that bundle listing at about £350, so this asking price sits in the believable middle of the market rather than feeling inflated. If anything, it’s a sensible buy only if the example is clean and complete.
What makes it appealing is the build: a beautifully machined alloy turntable mat/sheet that’s more about damping and presentation than gimmicks, and it has a loyal following for adding a touch of solidity and finish to the deck. Worth prioritizing if the original box or extras are included, since these accessories tend to appeal to careful owners and can be annoyingly easy to misplace.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Oyaide Electric traces its roots to 1952, when founder Kazuji Oyaide (also referred to as Katsuji Oyaide) opened a modest electrical wires shop in Tokyo's Akihabara district. Initially focused on magnet wires and industrial cables, the company incorporated in 1971 and pivoted fully to specialty wires by the mid-1970s, abandoning home appliance sales amid Japan's economic boom. A pivotal shift came in the 1980s, spurred by audio critic Saburo Egawa's insights on wire quality, leading to Oyaide's first audio products like the OR-800 speaker cable and OCB-1 power distribution box.
Oyaide specializes in high-performance audio cables and accessories, including interconnects, speaker cables, power cords, distribution blocks, connectors, and turntable components. Under presidents Satoru Murayama from 2000 and later Naoko Murayama, the brand expanded through strategic partnerships with expert manufacturers, emphasizing oxygen-free copper litz structures and precision engineering—all made in Japan.
Renowned among audiophiles for meticulous craftsmanship and the "genuine Japanese spirit," Oyaide occupies a solid niche in the mid-tier to upper-mid market, offering reliable upgrades without extravagant pricing. Its products enjoy a cult following in Japan and abroad for enhancing system clarity and dynamics, positioning it as a go-to for discerning buyers seeking value-driven Japanese precision over luxury exotica.
