Anyone listen to Zu Audio's Definition Mk3?

I have an interest in Zu speakers but do not know enough about cable connections to know if I can use my Belden banana plug cables that were placed under the carpet when the house was built.

Can anyone help? I have seen a picture of the rear of the Essence and cannot determine if I would have to re-wire.

A bottom line question -

After reading many statements about Zu, Tekton, and other cross overless speaker brands and unsuccessfully bidding on a pair of Essences can I simply put a system together without worrying about all of the detailed issues being discussed?

Can I place Omen Defs in a medium sized (open) family room with a modest 85 watt receiver (or find a used integrated amp like Melody which the Zu people mentioned would work) and a Marantz cd player together and not have to worry about what I am missing? Would I get better sound than from a 1992 pair of Emit Infinitys?
