I know your frustration. I can't isolate anymore. I hope the replacement takes care of it . I have hope since I never had this before with virtually the same set up but just with a diferent receiver and we seem to be the few with this problem. My Onkyo was cool as a pre/pro too but I sold it so I can not place it back for now. The 950 sounds so much better so I would hate it if it just was not compatible with my set up for whatever reason. I am not looking forward to shipping this one back . Do you think that our speakers are ok?
