OP wouldn’t you rather get to know the performance of a recording that you have experienced for many years and be able to recognize things changing from viewing your stage? It’s so much more fun to know a soundstage intimately and tune it in different ways to explore different aspects of the same recording. First you have to know how to get a soundstage consistently, but once that is an easy task, then it’s all about hearing the recording from many different points of reference. Sometimes you may want to spread the stage way out and other times not so wide and deep, but more condensed. There’s so many ways to listen to the same recording with all of them being right. Once you get to that type of control, double blind tests and other tests like that become boring and meaningless.
