Steve, when I listen to the new Dion album, Stomping Ground, on Qobuz the channel balance seems to be set to the left. It may be that that's the way the album was mixed or it may be that Qobuz got a bad file. With the millions of tracks they have there has to be problems in there somewhere. That's probably what you're hearing.
Audiogon has its share of internet characters and there are few threads that don't get some snark or other nonsense. It's best to just ignore it if you can. Some people just like to irritate others for some reason.
