Hi. I have had a conundrum for quite some time. I have Axiom m80s for front channels. I’ve got the center channel and the QS eights for rear which are posted on the sides of the room and an EP 500 subwoofer. I also have a pair of of M 22 Ti’s in the rear for 7.1 home theater. The problem is that I enjoy SACDs and DVDs audios and blu-rays of new releases of original quadraphonic music, which is 4-channel. Is there some way to deactivate the qs-8s while listening to surround sources? Quad just does not sound right coming from the QS eights instead of from behind. And actually the multi channel releases to me would sound better with rear channels instead of side channels. I don’t know if anybody else has experienced this but it’s been kind of a conundrum for a while for me. I have a vintage set up and can listen to the original sources but the remasters and many of these are wonderful and so simple to use but I would like to be able to enjoy them on my Axiom Audio system. I use a Denon 4310 receiver and oppo 203 player for this. For stereo from my rega p6 and other stereo sources, my music is wonderful, but the setup is not so good for my other listening. Any ideas for me? I appreciate any suggestions and opinions you may have. Thanks a bunch!
