For mono cables with an outer diameter of about 4mm such as Mogami 2314, Evidence Audio Monorail and Blackrock. The ESP-RA is the first solderable 1/4" phone connector from Evidence Audio and designed (like all of our products) with the primary purpose to sound demonstrably better than anything in it's class. 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. Width 15 mm Height 23 mm Depth 8 mm. No really…these fit everything!
