I had my monblocks fitted with SpeakONs (as mentioned by Erik) and love them. Benchmark Systems says they provide the lowest measurable distortion of connectors they tried; they are easy to connect and disconnect; they are impossible to short out; and they are inexpensive and plain looking. This list includes many reasons why they never will be adopted by high-end audiophiles. They are just too simple, effective, homely, and inexpensive to be audio jewelry.
Connecting Amp to speakers
The humble banana plug, has not changed in its basic design since it’s invention, which I believe to be around 1929, many adaptations, but all following the basic design, so am I right in assuming this is the most efficient way to connect all these high end speakers and amps, which are discussed in these columns in great detail with their perceived audio attributes, along with speaker cable costing mega bucks, and all connected, I am assuming, to each other by a banana plug. Maybe the top flight kit has an alternative connecting system??
