WBT Banana Connectors

Yes, I like the tightening feature.

I used to run 3 amps, 3 sets of speaker cables with male bananas to female banana pigtails from my speakers I could easily reach.

McIntosh SS MC2250 (mid 80’s);

Fisher 500C Tube Receiver, 1964

Fisher Tube Mono-Blocks, 80Az, 1958

everyone preferred the 500c to the mc2250, and preferred the 80az to the 500c.

and, same content: preferred LP to CD, and preferred R2R tape to LP.

I've had Furutech and WBT and WBT was by _far_ the better quality connector.

Having said that I've switched to inexpensive brand below for my latest speaker cables.  I have 2-way monitors with external crossovers, so 3 cables per speaker. Very pleased with the results. The spring action makes them stay very tight even in larger openings when pushed upwards (long story but my crossover's connectors face straight down).
