connecting B&W 683s1 to amp? help please?

A single set of high quality speaker cables with jumpers will sound much better than cheap biwire (as seen in your link).
You can strip any piece of wire to make jumpers. Lamp cord or an extra extension cord will do temporarily. Then order a set of jumpers like these..

these 683's are a step up from my pioneers which I think were better than the LS50w's
I'm gonna get a used NAD amp next  (they're plentiful around my parts) as I'm not sure the Luxman has enough juice although it sounds as if it does

also inserted a dragonfly black into the chain which helps a tad, but can't really hear a difference on Tidal MQA compared to my flac downloads

Or some paper clips straightened out will do in a pinch if long enough....
