Sorry, I forgot to say:-
1) Welcome to the forum afcintra!
2) Yes, you CAN use Beolab 2 and 7.2 with a generic A/V processor, in case anyone was wondering, you just have to send the correct trigger signals to switch on the speakers when no B&O source is present.
Kind regards, Steve.
By the way, Steve, I am using your cables to connect the BL3s to a QUAD CD player and they sound great!
