ricevs Do you own speakers made with Cube Audio drivers or similar widebanders?  Do you know anyone who owns complete (with cabinet) Cube Audio speakers who has replaced the wire as you suggest?  Do you have a recommendation for "some great sounding wire" that would make us "guys weep with joy over your sound"?  Pls suggest what would be the very best wire regardless of cost.  We don't have to buy much and while my Nens do make me weep on occasion I could handle more.
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.

I like the tempo electric solid core silver in Teflon (and use VH audio solid core silver in my interconnects and components).
For Nenuphar (reg or mini) owners, how far apart are your speakers and do you tow them in? I have minis and I just moved. My new room is bigger than the one before. I’m working on setting up the speakers and they’re very “beamy” at this point where the sound seems to coming right from the drivers. I just moved them further apart with almost no toe in and it’s better but still a bit beamy. Maybe I’ll move a bit further still. Just wondering how everyone else is set up. Thanks.

Rough (and general) numbers for my system with the Nenuphars:

~ 9.5 ft from the front wall (to the front of the speakers)

~ 7.5 ft apart (center of driver to center of driver)

~ 7 ft from the listening position

~ 15 to 20 degree toe in

Room size: 26 by 19 by 9
