Gold coated brass speaker spades

Direct from the source:  I inquired and Tara told me Brass with Gold Plating.

They do not offer a chance to upgrade.

Brass might be cheaper than copper, but, do we really know that it is bad for sound or that it is a bad choice to do cost cutting on the choice of spades vs. cost cutting elsewhere?  Presumably, only the very top models of these companies represent no cost cutting/no compromises in the execution.  

what we really know that we are paying for brand namez and not much for product. the way around is to purchase bulk wires for cheap from sites such as newark.com or digikey.com and build own speaker wire with pure copper. even if you decide to purchase silver wires, it will still be cheaper than purchasing terminated cable with brass wire.

What @larryi said old school brass binding posts sound fantastic particularly in the bass regions.

I personally would not use copper plated brass, there are too many good cables available from too many companies to do otherwise. Gold plated copper, gold plated over silver over copper......or if you like rhodium (which I do not)
