Spades vs. Banana plugs ??

Bananas,  My Naim Supernait 3 only except Bananas.

My Furetech spades haven't ever came  loose on wbt binding post although I broke one wbt post over tightening it. The trick is to get its tightness just right. You have to turn the spade along with the post.  Also I installed the wbt's myself farther apart than most speakers would come from the factory leaving plenty of room for them not to spin around and touch.  Next time I might go with bananas though 

Anyone know if they make a speaker cable that's terminated with a combination of both spade and banana connectors?

Double the surface contact, best of both worlds!

For what it’s worth, coming from Monoprice 12g wire with Nakamichi bananas, I went with the Viborg pure copper banana plugs on Furutech FS-A36 12g speaker cable. I tried one speaker with the Nakamichi & the other with the Viborg both treated with Stabilant & the Viborg & the OCC Copper made a HUGE difference. And I thought my system sounded good before the change. Also when I did the UPGRADE, I tried the Viborg pure silver & lost the ''3D/openness'' of the pure copper. 

@thecarpathian Brilliant idea. It would be easy to implement  using a double double bi- wire design and blow peoples minds.
