In Reply to: RE: CMC CMC-6005-CU-R Bare Copper Spade posted by Duster on June 16, 2017 at 00:00:50
I still like Cardas GRSC copper spades but I don't see the unplated copper version listed on the Partsconnexion or Sonic Craft websites any more so your CMC 6005s may be a good alternative, and less expensive. Another alternative is to purchase the Cardas copper jumpers, cut off the link, and solder your wires to the two individual spades. $6.74 per jumper, or $3.37 per individual spade.

The downside of the GRS spade is the size factor; I've experienced enough frustration about a misfit between 1/4" vs. 5/16" binding posts and spades that aren't universal fit. The CMC 6005 fits both sizes, and provides options for both a heavy-duty crimp termination and strain-relief. Otherwise, I'll only invest in modular connector designs like the WBT spade along with a crimped ferrule sleeve, so any size can be swapped-out as I've done before without essentially re-terminating the cable. It was a great relief after upgrading a power amplifier with a newer one that features a larger 5/16" binding post. A real relief to not experience unfortunate audiophile grief at that time.
I own a set of WBT with one no longer usable. I had used them and wanted to change the wire but the set screws in one of the WBT was frozen solid. It broke the WBT tool, AND another torx tool.
I think I over tightened it...
If the WBT might ever be reused or re-purposed, I suggest using a anti seize compound on the set screw threads..
The key to using set screw speaker cable connectors is implementing a copper crimp sleeve. That way there is more resistance to torque when tightening the set screws, with more subtle tightening involved rather than cranking-down on unrestrained wires within the termination point. The holding-power is much better via a copper crimp sleeve within the connector body, in any case. YMMV
I have no trouble with the Cardas spades on my Cardas binding posts. I used a lot of Furutech gold over copper spades too.I no longer use the WBT spades so if you are interested in a good deal on a set of four new/never used WBT spades as shown above, let me know.

My point is about a universal fit vs. a specific size as a limitation.
Shoot me an email with a price, and I'll let you if I'm interested in a purchase.
Luminous Audio makes a nice simple spade in gold, copper or silver. I've used them many times over the years, and have never been disappointed in their performance (bare copper).
