Gold coated brass speaker spades

GTX-D specs:

• Rhodium or gold-plated α (Alpha) Pure Copper Conductor (0.8mm)  • Nonmagnetic stainless conductor spring system  • Body material: Nylon/fiberglass with piezo ceramic and carbon damping material • Cover material: Polycarbonate  • Parts set with nonmagnetic 2.0mm-thick stainless brace plate • Specified for wire diameters of 4mm (set screw) • Dimensions: 104.0 mm (L) x 47.2 mm (W) x 28.0 mm (H)  • Total attention to detail and build quality extends right down to a specially designed patent-pending conductor pressure plate (see below) that increases contact area  • Furutech spade terminal FP-205 recommended for 10 AWG wire 

Yes both the Furutech GTX-D (both gold and rhodium plated) are UL rated, as is my second favorite Oyaide R-1. I own both, and just double checked them

Confirmed, it actually states that at the beginning of the second video I posted above, and one can see the UL logo on the front of the plug. 

I don't suppose you have tried the Shunyata one?

I did not compare the Shunyata receptacle. I tested several models of Furutechs, Oyaides, Pangea (which I already owned), Cardas, Synergistic, Acme Audio Labs, Levitons, and maybe some others......testing was just over a year long.

The Acme Audio Labs silver Cryo and CFC, were surprisingly good at their modest $60 price......revealing, but not as much as the rhodium Furutechs which take forever to break in

This thread is all about the brass.

It's all about brass being same as OFC and even Silver. All three materials can be used in audio wires and all will sound nearly same.
