For your interconnects, silver - pure, soft temper silver, not plated on copper, is by far the most accurate conduit for musical information. In a twisted-pair configuration without a coaxial shield, and passing inside inside a loose Teflon insulator, this cable can achieve incredibly low capacitance - meaning the signal passing through it will not be hindered or colored in any was. Transparent as fine crystal.
That’s the basic science - and being that this cable is a relatively simple design, it will be well within your budget.
So who makes this wonderful interconnect?
