The ESP-RA is the first solderable 1/4″ phone connector from Evidence Audio and designed with the primary purpose to sound demonstrably better than anything in it’s class. Compatible with our PTMC balanced patch cable.
The contact points of the ESP-RA are machined from a high-copper-content brass. Brass offers the appropriate hardness and strength required for a connector with very good conductivity to minimize distortions caused by the cable the plugs are used on.
The form factor is akin to a “pancake” style plug, with a patent-pending closure system that allows for the plug to be assembled with one screw instead of two. This allows for a smaller form-factor as well as reduced assembly time.
6.35mm plug dimensions: 8mm [body thickness] × 15mm [body width] × 23mm [body length]
