Picked up a set of these for the speaker end of the cables. I like the BFA-style bananas as I think you get more surface area contact with them than with either spades or bare wire into a speaker binding post, and I bought the AQ's as they are one of the few available that have the outer gold plating applied directly to beryllium copper (no brass or nickel plating between). With the copper-only base metal I didn't expect them to be as rigid or have the "spring-back" that a brass or nickel substrate would offer, but what I didn't expect was the copper to be so thin that just the weight of the cable hanging off the end deforms it enough to marginalize the contact. Easy enough to pry the end back open to where it would offer a snug fit, until you insert it again and it almost collapses on itself. If I had to guess, I'd estimate the gold plating and copper together might amount to about 28 or 30 gauge thickness -- or about the same as a doubled-up piece of aluminum foil.
I'm going to try and return them (bought through Amazon), but as mangled up as they look right now from my trials to get them to stay in place it may be a long shot. I've been pleased or at least satisfied with everything I've purchased from Audioquest over the years, but these are a BIG fail...
