I have recently purchased a set of Andra II speakers, and I am currently bi-wiring them with two separate sets of (2M) Audience AU24 speakers cables. They sound very good to me, but I will state that I have not tried them in any other type of configuration (i.e with jumpers), or with any other type of wire, (although, I would love to try them with a set of bi-wired Nordost Valhallas). Sorry I can not help you with the comparison.
I suggest that you do a search of the members systems here on Audiogon that have the Andra II speakers, and contact them to see what experimentation they have done.
And, you are correct that the current standard configuration is with two sets of binding posts, for bi-wiring the speakers. (Obviously, as Ontjesr has done, you can special order them with one set of binding posts.)
(Note: The Andra I was set up for a single set of binding posts, although if they are upgraded to the Andra II version, the owner has the option of either keeping the single set of binding posts, or going with the now standard two sets of binding posts.)
Good Luck with your search and let us know what conclusions you come up with.
