The hollow bananas have become a standard for almost all manufacturers of quality speaker cables, who use various versions of this type of banana even in their most expensive HiEnd cables. Specifically, Cyrus uses sockets (terminals) in the outputs of its amplifiers that exclusively accept this type of banana! These bananas are truly exceptional for their price, considering that the price is for a set of 8 pieces! The direct silver plating (without the presence of noisy nickel) and the body made of copper, not brass, make them extremely good-sounding. Yes, they are somewhat more delicate than usual, they do not tolerate mishandling, but this is in favor of sound quality, which personally I wouldn't trade for anything. With a little care, you will have no problem, and the benefit to the sound will compensate you. I have been using this type of banana for years and have never had a problem. They accept cables up to 11 AWG (about 4mm^2) and tighten them very effectively with two screws (the best way), but they also allow for soldering.
