I just bought some Eichmann Bayonet plugs for some speaker termination. My biggest complaint and the reason I would never buy them again, is that they were extremely difficult to fit into the speaker connectors on both my speakers and amp.
Eichmann Bayonet plugs user experience
I was going to have a new speaker cables terminated with the eichmann bayonet plugs, when the dealer advise me of this situation:
"We've found that, while there is a small reliability issue with Bayonet plugs, it's not due to the solder connection. There's a nylon shaft with a copper sheath wrapped around it and in some cases we've seen the copper shaft bend away from the nylon sheath. While we think the Bayonet is the best sounding connector for speaker cables, we do like to inform customers about this issue. But they work just fine, and we do recommend the Bayonet plugs. You just have to be a little more careful with them."
Just wonder if other users have encountered the same issue.
