Sonos, Zeppelin, q acoustics 2010

I have a standard sonos set up and I connect the zoneplayer 90 to a zeppelin and I plan to connect the zoneplayer 120 (already brought) to some q acoustics 2010 (about to buy and have space issues).

So what connections should I use to get the best sounds between each, Currently the zeppelin is using the standard wires as my new interconnects didn't fit. It has a narrow entry into the zeppelin and my lead plug is too flat to get in. I am looking for advice as to the leads and the ends that you need

Thanks
