Yeah I have lots of music, that's not really the problem, it's more knowing a specific track which is technically
(as opposed to subjectively) a good test. In other words (I suppose), one which tests the highs, mids and lows, has lots of detail and dynamics, plenty of layering and texture (I suppose. I'm not an expert).
In the same way that you can test how good two cameras are by taking a photo of the same scene, even if that scene is not attractive, I wonder if there is an equivalent for audiophiles.
Perhaps it doesn't even have to be music, it could be a particular white/brown noise or something. Just anything that is produced such that it will expose differences between different audio setups.
