I received my 533-VAC today, which replaced a 422-C. My receiver (Yamaha HTR-5990) has an automatic speaker configuration feature, which thinks that the phase of my connection to 533-VAC is reversed. In other words, I have to connect the + of the receiver to the - of the 533-VAC, and vice versa, to make the receiver believe that the phase is right. The receiver didn't have an issue with the 422-C. Is it possible that the 533-VAC I got today has been wired wrong internally? The Yamaha documentation also warns that sometimes the auto configuration feature could get the phase wrong. So, what do I do now? Believe the speaker or the receiver? Thanks
