My opinion was generally about commenting about knocking things other that people like. Since you don't own it you have no idea if a well designed enclosure will make a sound difference.
So asking for a rationale is "knocking down"? People are free to like whatever they want - I was just wondering if there is a rationale, apart from aesthetics.
I can tell you that 20 years ago, my CD player sounded different on the floor than in an audio rack.
If you say so. I would fire the designer of that CD player.
