AECO ABI-0611S vs ETI CRYO
I had the opportunity to compare the 0611S binding post with the ETI KRYO Silver Plated Tellurium Copper. (ETI KRYO Silver Plated is not certain to be cryo-treated either, because there is no information on the manufacturer's website https://eti-research.com/connector/kryo-binding-post/ ) Both have the same conductor (tellurium copper) and silver plating. The direct clamping of the spade and wire is the same and practical. It can be soldered on the inside and also fixed with a screw. There are two differences. The AECO fixes the wire with screw through a removable optional hard material ring. The other difference is that the AECO clamping cylinder is grooved for gripping the fork, which allows you to clamp the fork on heavy cables more firmly. I don't think the two sound different, I like the 0611S better and it is much more affordable price.
