A great topic!
Art Dudley included the subject of the ability of superior hi-fi components to afford the listener deeper access into the musical performances contained in recordings, irrespective of the "sound" of the recordings and/or component(s). He held that it was a matter of the ability of the component/system to "play the music", an ability separate from the quality of the "sound" of same.
Listening to a hi-fi tends to raise our expectations. I don’t expect a car CD player to make music sound "good", so when it doesn’t I’m not disappointed.
