Thanks for all the info. I noticed that the vp-150 is 6 ohms and the qs-8 is 8 ohms. Since I'm considering getting those with the m80s, does it matter to the receiver that they are all different? I assume not since I haven't read about any real issues regarding this. I also assume that lots of people with axiom HT systems have receivers like mine and have no issues. Thanks again.
