I've got a couple of beautiful Clements Audio Speakers with Ribbon Tweeters that can handle an immense amount of power. I've had them hooked up to a ZP120 and they sounded great, but I recently picked up a 2nd ZP120 and tried using the left channel of one and the right channel of the other to drive the pair of speakers and they literally "came alive". Controlling the volume on them is no problem as long as take the two amps and group them together but when I add them to a larger group, (I've got components and Zones all over the house) it becomes problematic. I need to control left and right independantly. Is there a way to set up 2 Amps as a stereo pair as can be done with a pair of Play 1, 3, or 5s?
