AudioQuestSureGrip 100 Banana Gold Connector Set of 8 (2020)

Work great and fit very tight into my klipsch speakers and marantz receiver. The contact is so good that my volume difference compared to bare wire is a lot louder and more clear.

I went with this style of banana plug since they grip the banana jacks much tighter inside than the spring-loaded types. They are also made of a copper alloy, which is more conductive than the brass that many other manufacturers use.Two notes about how these fasten to your wiring. I used these with a bulk length of Kimber 8PR speaker cable, which has eight insulated runs of wire per polarity (eight brown, eight black). The strands inside each run are of a different gauge. These banana plugs attach to your wiring using two small setscrews. You need a good amount of wire inside the barrel for these screws to tighten down on. In my case, I am bi-wiring a pair of speakers and found in my testing that running three conductors to the treble/midrange and five to the bass/sub-bass drivers worked out the best. Because these plugs need a lot of wire to clamp down on, the three conductors would not stay put until I folded the conductors over on themselves inside the barrel. If there is not enough cable inside the barrel, the setscrews will screw their way inside, and out of the threaded portion of the barrel. The five conductors applied just about enough force to clamp securely with the banana plug.I am tempted to see if I could solder these with some Cardas solder, and then finish the ends with heat shrink tubing.One neat feature of these plugs is that the insulator barrel screws on from the opposite end, so, if you have ever forgotten to thread your barrels onto your cables in the past, don't worry about it here--the barrels go on last.

Some of the terminals were unusable. Would not recommend

Like them very much, love the set screws to hold the wire in place works great.

Great product.

Excellent

The tips that plug into speakers or amplifiers are too flimsy and easily get bent out of shape.The locking screws need a lot wire stuffed into the connector for the screws to come to a stop at the right place. Too little wire and the screws would fall into the connector body. Very fiddly.The banana tips are too long for the terminals on my amplifier. A lot uninsulated metal from the tip is sticking out.

As with most Audioquest gear, these are overpriced. I bought this set to replace the banana connectors on the speaker ends of some AQ Type 4 speaker cables which had been lost through the course of several recent moves. $38+ is really pushing the envelope for what you get here, but I wanted to make sure that I was buying connectors from the same company that produces the non-standard conductor configuration as found in the aforementioned cables. The little hex key is a nice touch and overall the quality seems to be pretty good. That said, I can't help but chuckle a little bit every time I see the "Speaker" and "Amp" reminders to keep an unwitting audiophile from connecting their "directional" copper cables in the "wrong" direction. In fact I reversed mine on purpose and I'm living with my $7K setup sounding like a boom box just to spite Audioquest. (that was a joke - switching the "directionality" of AudioQuest speaker cables makes absolutely zero difference in the sound)
