Single output at amp, tri wire at speaker. Any benefit?

My Parasound Halo Hint 6 has one pair of speaker outputs per channel
The ATC SCM40 have triwire capability.

I currently run a single cable from amp to one terminal pair in the speaker and use jumpers between the terminals.

Any benefit in crimping three cables together at the amp end plug and run them to each terminal pair?

In my head, it's the same as using jumpers. But is it really? 

Please advise.

Thank you . Haha! The solutions proposed are so logical. Silly of me to not have tried those out first. 
I will do the binding post jump first.
