Speaker cable for ATC scm 7,11,19 ??

What cable are you using for ATC?
I like neutral, detailed and revealing sound...
with good image and dynamics.
DNM cables swing.
What is the better choice sigle or bi-wiring??
I suspect bi-wiring will be better if you also bi-amp. Otherwise it is really a wash (as you are shorting the wires at the amp end anyway).
