Hi everyone, I'm new to the forum so hopefully I've posted this in the right section. I'm looking to purchase a receiver to power 2 sets of in ceiling speakers. I have 2 polk audio's in our master bedroom and 2 in the ensuite bathroom. I'm looking for a receiver that has the speaker A/B and A+B capabilities so I don't have to use a switch box. Does anyone have any recommendations, preferrably something affordable as I spent most of my money on my living room setup and these speakers/wiring. Thanks in advance.
