Hello again fellow HT lovers, I have a Sony DA5ES receiver that has 4/8 ohm switch on the back. I have some older Infinity floorstanding speakers that are 6 ohms. My center channel is also matched at 6 ohms. My rears are 8 ohms, and I just ordered a subwoofer that I am assuming is 8 ohms. What setting should I have the receiver set to? I tried both, but not sure what to listen for to discern a difference. Which one in theory would produce a better sound?
