More likely your connectors needed a good cleaning. :)
Can hardware change speaker phasing over time??
After years of great listening, I suddenly noticed I wasn't getting the sharp center image with vocals. I spent hours moving the speakers and even did Room EQ on my Denon receiver (which normally would tell me if speakers are out of phase). The vocals sounded diffuse. Finally, I switched the wires on one speaker. BOOM! Right back to crystal clear center imaging on vocals, on all of my favorite tracks. I've checked all the wires. Everything is hooked up right, though now red is hooked to black on one speaker.
Could something have changed the phasing in the hardware? There is no other place in the set up the wires could have been reversed. I have triple-checked that the ++++ cable is connected to the red output on the amp.
Signal goes from Mac Mini by USB to Bryston DAC, by two single channel cables to Denon receiver, by two single channel cables to Parasound A21 Halo amp, by speaker wires (one wire marked ++++) to B&W CM10s.

I also just tested this with a Stereophile Test CD (which bypasses the DAC), and the speakers definitely meet the test for being "in phase" though they are wired out of phase. (Disk 1 "The fender bass was recorded equally in each channel...") My point is that everything was fine for years, and then suddenly I wasn’t hearing what I was used to. There is no evidence anybody changed anything in the system. It’s been this way a really long time. I also just re-ran the Denon Audyssey room check, and now it’s telling me the Front Left is out of phase. And yet, the imaging is back to normal as if the speakers are actually in perfect phase. |
There really is only one explanation for mysteriously reversing wires like this. If you want to avoid further problems I suggest you pay close attention to this video, lest the situation escalate. https://www.youtube.com/watch?v=wW370Aj8E6g |
