Mine never has been daisy chained, there's a splitter at the AVR and from there each sub cable gets plugged into a wall plate with individual cable runs going to each subwoofer location throughout the room.

I've never though too terribly much regarding the 600 and the 350 not playing well together because I knew bringing the old 350 into the mix was like bowling with a marble but if there is a problem with the 600's amp I sure would like to have it rectified.
