Image: CMC 6005 Gold Plated and Bare Copper Spades; CMC CMC-6005-CU-R Bare Copper Spades
While pondering copper spade connectors for a new DIY project, I came across a perfect example of identifying two types of audio connector platings, and how important model numbers can be. Both can be difficult to discern without clear photos and truthful if not coherent descriptions, especially Chinese products and listings that are often full of misinformation if not misleading content, so buyers should be aware. That said, I have found excellent Chinese devices that tend to be worthwhile things to explore, especially when seeking bottom-line if not wholesale price points. Not unlike the rise of Japan in the electronics marketplace, Chinese products should no longer be considered junk as a rule, since higher standards are slowly being introduced as Chinese culture becomes more sophisticated about how they perceive the worldwide audiophile marketplace.
Two Chinese brands, EIZZ and CMC are reputable audiophile connector makers, but both suffer from poor website content in order to support their products, so gathering as much information as possible from the web has been necessary. In the case of my copper spade research, I determined a set of 10 (although I only required a total of 8) copper spades for under $20 with free shipping was my lower-cost target for the application. I decided on the CMC 6005, since it features a pure copper base metal, and a dual solder/crimp/strain-relief platform design, and a universal fit for any size binding post.
That said, I found two types involved in eBay and other listings; CMC 6005 models indicating a superior design, and another without a designated model number featuring an obvious nickel substrate plating that I find undesirable, although lower in cost. From what I gather, this lower-cost product is a counterfeit CMC product, which is ironic since Chinese knock-offs tend to be based on Japanese, North American, or European audiophile products rather Chinese brands.
A fortunate find was this AliExpress listing for direct gold plated pure copper CMC 6005 spades, but what was delivered was the unplated CMC-6005-CU-R version, which is the model I originally sought at best-price, since I fully enjoy bare copper speaker connectors. The appearance of the bare copper CMC-6005-CU-R is spot-on to how the bare copper Cardas GRS stamped spade looks, except that the CMC-6005-CU-R is a universal-fit design, and features two termination platforms; one for soldering or crimping the conductor, the other to crimp the insulated wire for strain relief purposes.
