Has anyone used The CMC 6005 Speaker Spades


Wondering is anyone has used the Charming Music Conductor 6005 speaker spades. They apparently do not have a rep in the USA and must be ordered from China. All of their stuff says pure copper with different plating options. If you have used please let me know how well they worked for you.

Seems they are not well used in the states. Thanks to those that looked.
Happy listening.
