I have been waiting ages to upgrade my lowly Yamaha Pro Logic stand alone processor to the delights of Dolby Digital, DTS etc,etc,etc and Pro Logic II, The last time I spoke to Yamaha they said they hadnt one in the pipeline as we (UK) were the only market for stand alone processors. As I have a Audiolab 8000A amp and 8000PX power amp, running the front main speakers I was wondering. 1/ Would be possible to add a surround Amp/Receiver to the system and not have it running my main stereo speakers (still use my Audiolab for them)? 2/ If so would I be able to use a test signal on all the speakers in the system? 3/ Would I just hook it up the same way I presently have the Yamaha processor? 4/ And as I presently have a QED switching box for extra inputs would I be able to take it out of the system and link my components that used it through the new Amp/Receiver up to my Audiolab equipment?
