Oyaide P-004E Schuko Power Connector These are the best quality plugs I have ever used and sound richer and more natural than the similarly priced Furutech NCF FI-50 schuko connectors. Currently retail for £300 + VAT (£360) in the UK. Blurb: Oyaide P-004e is a high-end audiophile-grade schuko plug that has been designed to obtain the best possible sound, Oyaide go to great lengths in choosing the right materials to achieve the best possible results, many music lovers swear by the quality of these plugs. The contacts of P-004/C-004 are heat-treated to ensure electromechanical integrity. The 1.0mm thick and 6.0mm wide contacts provide maximum contact area have more than 8kg of holding power and reduce vibrations at the point of contact with no loss of signal transmission Plating – The manufacturing process is started from foundation coating. The material which was punched out as a part is polished by hand piece by piece after machined barrel-polishing. The plating of the P-004/C-004 is a combination of platinum and palladium which were selected as a result of repeated listening tests. The inner platinum layer is 0.5 microns thick and the outer palladium layer is 0.3 microns thick GF-PTB body – 30% glass-filled PBT has excellent machine-ability and provides superior electrical isolation. The highly rigid body of the P-004/C-004 effectively attenuates high-speed vibrations. All screws, which were originally designed for P/C series, are made of highly rigid stainless steel which is a non-magnetic substance. Moreover, the cable cannot be separated from the plug by a force less than 30kg, a significant safety feature. Outer cover – The outer cover of P/C series is made of PC(PolyCarbonate) for its rigidity and hardness. It helps to attenuate tiny vibrations in quick response and reduce distortions by its superior mechanical strength. Specs:Contacts: Berryllium copperPlatinum Platinum 0.5? + Palladium 0.3?

Only damage to mention is to the rear rubber seal which has split (see photo). Ive yet to fit a thick cable to any plug without the seal eventually splitting!. Includes Oyaide storage tin and wiring instructions. A few weeks after buying these Oyaide plugs I switched to American style plugs (as I bought a PS Audio mains generator with American sockets) so they have had little use. Listing details: I have two of these plugs (both identical), please contact me if interested in both. Collection welcome or will send fully insured. Thank you.
