Hi everyone,

I just bought a pair of CM2's. They're powered by an uncoupled
Yamaha AX 570 (Luxman pre-amp/tuner for control), and thus far I'm
pleased. But I'm already wondering about bi-amping them. Does the
second amp have to match the Yamaha, or visa-versa? Does this require
a central controller to match power output from the dual sources?

TIA

Yes. You need some way to balance the output levels of the amps.
