It could change the sound. In my room, removing the audio rack changed the sound.

Of course - vibration, resonance and microphonics have an effect on SQ... I mean a huge part of speaker design is spent on these aspects. And obviously the speakers interact with the room, etc

One, like me, could believe that @Wiimer meant removing the rack including all audio devices on it, will change the sound. In that case very audible

Spotting an immediate difference between two near-identical things is a completely different activity to revising for an exam.
