No, do not own Cube speakers nor know anyone who does. No one in the world has done what I suggest......you could be the first! I do know someone who has done this to his $1200 a pair Lii Silver 10 speakers (mounted on the open baffle described above). Yes, I have done this to many speakers and make my own speakers and have since the mid 70s. I have modded and manufactured gear since the late 70s. I bean around the block. People will argue all day about what is the worlds greatest hook up wire. I really don't know. But any great wire will work fantastic in the scenario described. It is the removing of the banana jack, the banana plug, the WBT connector and (if possible) your spade on your speaker wire that will make the most difference. Of course, you want great wire....here are some suggestions:
Parallel single strand PCOCC Chris Venhaus wire
Parallel silver gold Mundorf wire.
Neotech copper litz braid wire....parallel several 20 gauges or get some 14 gauge from Zen Wave.
