sorry for stressing this topic once again ...

... so the "E" version (high capacity) might as well be used as the "normal" version?

The high capacity 'E' version can handle 5 A. The non-'E' version can handle 3 A. They're interchangeable in this application but the 'E' version is more expensive.

Attached figure is from Page 2 of the data sheet and explains the difference between the normal and high-capacity versions of the relay.

An easy way to find the data sheet is to type the part number into Mouser. The product page will have a data sheet link near the top of the page. Alternatively, one can type the part number into Google. That works for the relay in this case, but for other parts getting Google to come up with the data sheet hosted by the manufacturer can be a bit of a gong show. Mouser (or the manufacturer's website) is more handy for that.

so today I'd need some advice regarding binding posts. i see a lot of fancy ones that seem to be crazy expensive and I also found these that a very cheap but are not "designed for hifi" .... Hirschmann

are any significant differences to be expected .... other than the fact that they look different?
