I own the Marantz PM6004 hooked up to Dali Zensor 1's with Mogami W2921 cable and I think it sounds fantastic. The Mogami's are a loan set and not paid for yet. Not especially cheap and I wouldn't have purposefully gone out to spend as much on cable but it does sound fantastic and night & day better than when I switched in my previous cables (QED Anniversay).
On each speaker, the copper band (jumper) will connect both +ve's and both -ve's together. You then simply connect the speaker cable from your amp to either of the terminals, observing polarity throughout of course. +ve from amp to +ve on speaker (either terminal) and the same for the -ve's. Very important that +ve goes to +ve and -ve to -ve. Won't cause any damage, but won't sound right if you get it wrong.
