This Furutech FP-Mono-63L(G) Angled Jack 6.3mm connector has a very nice finish and uses excellent materials, ideal for creating high quality mono cables. Note that the connector is designed in a single piece and benefits from gold-plated copper alloy contacts treated Alpha (cryopreservation) for maximum conductivity. The connector also benefits from PBT insulation to limit interferences and a stainless structure.
