Speaker binding posts with plastic covers


My Krell amplifier has speaker binding posts with the clear plastic covers. Apparently these are for EU safety requirements. I want to use spade connectors and have no idea how to open these covers. I’ve wrestled with them but they don’t budge. I don’t even know whether they unscrew or pull out or whether there is some other method at play. Does anyone have experience with these?

Those speaker posts look pretty much identical to the posts that came on the Parasound A21+ which I owned.  If the same, just unscrew the cap as you would most binding posts.  The only semi-difficult thing was figuring out how the spade connected, as it needs to be at a certain angle.  Once figured out, it holds the spade exceptionally well.

I doubt Krell would adopt a different, less convenient binding post, at least for US sales.

Again, assuming they are like the speaker posts on the A21+ I owned, they were the best speaker terminals I have used.  Without having to yank them vice tight like on other speakers posts on a handful of amps I have owned, they held my speaker spades with an iron grip.  Part of the plastic holds the spades so they will not rotate.  Once you see how the spade needs to fit into the terminal, you are good to go.
