It's all about the brain. Let me explain myself.
The movie theaters have better sound systems that the Home Theater we just built. Yet I am not impressed by the sound there as I am impressed by the sound home. Why is that? I came to the conclusion that it is about the fact I am used to the movie theater sound. My brain expects a certain sound quality, and it gets it, so this is assumed to be normal. However, this audio quality is not expected in a living room, because I've been in living rooms before and they don't sound awesome; that is the normal condition for my brain. Therefore it is a surprise to hear such quality.
I am impressed by my speakers not because it is the best sound ever, but because it is the best sound I ever had home. It's all about what the brain is accustomed to.
