Hello everyone, I hope someone might still be paying attention to this old thread. I've been scanning through a bunch of posts/threads about possibly connecting two amps to a single speaker...in my case for comparison of a Denon POA-2200 + Denon PRA - 1100 combo VS a NAD C372 integrated amp. I have no switcher unit available...all I have is the A+ B inputs of either Amp.
I am not clear on whether or not it's possible to use these switchers as a sort of substitute for an Amp A/B switcher. I don't mean using the switch to cycle between amps. I just mean using the switch to stop either amp from trying to driver the other's output stage, by turning off the A or B terminals of the amp not in use. Basically I am wondering if those A + B speaker terminals can be disabled effectively or is it the same as just turning off the HT receiver, the other amp will still detect and try to drive the output stage of the HT receiver.
