Spades vs. Banana plugs ??

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

+1 bare wire.

Answered definitively in a prior thread that bananas are the only sensible choice. 

All meant in good fun though.

@oldaudiophile @davetheoilguy P.S. Re bare wire and gauge, I use ~AWG 4-5 (so VERY thick) bare wires. Took a bit of fiddling to get them in neat, but works fine both amp (Pass XA25) and speaker (PearlAcoustics Sibelius) side. And no, they don't get loose. I have not done a pull up on them, but no unreasonable amount of pulling will move them.
