AURIC OHNO wire employs a cross linked polyethylene dialectric. Cross linked polyethylene has dialectric properties very close to Teflon without its drawbacks, specifically stiffness and weight. The wire is cast using the proprietary OHNO casting process and is Cryo treated immediately following production. We spent a lot of time looking for a wire which offers absolute fidelity and performance. Auric OHNO is the best sounding wire we have ever heard and that is precisely the reason it is used in all of our top of the line products.
