I have 3 sets of 8ohm speakers in the same room. I will not entertain playing all three but 2 I think is an option.
I have a Niles speaker selector w/ a protection button on the end I believe it's for this purpose. Now I also think my Adcom wouldn't break a sweat w/ this either.I just want to know if this is advised ,stupid ,or not healthy for the gear involved. Why you ask ,only because I can no other reason and of course it's not needed between any of the sets I have.
