Stereo image off-center

Check with a mono recording, not with Diana Krall.

Sounds like you need to check everything.

I used to get intermittant off-center, turned out to be the old corroded, and slightly smaller rca jacks on my vintage McIntosh tuner/preamp. Move any cable of any piece of equipment, a contact on the tuner/preamp might get disturbed, one channel making a better contact than the other.

Audio Classics replaced all the rca jacks with new tight gold plated ones, problem gone.

And I now use cables with locking rca jacks, mess about with anything, they stay firmly connected. 

There are occasional tracks recorded with off-center imaging. The more revealing/imaging your system, the more you become aware of this.

For that reason, I am a big fan of Balance Controls, especially remote balance.

asctim, erik_squires, gosta  thanks for testing.

ddd1, elliottbnewcombjr thanks for the suggestion, but I wanted to if this particular recording is off-center.

fuzztone so you hearing with your ears now, are you?   

Center for vinyl and Tidal

Streaming from Qobuz, vocals dead center and piano mostly right.
