Reverberant floors and walls help carry the sound from a tiny instrument all the way to the back of the hall. This is good so you can hear the music from far away.
Some reflection in your listening room is good, but too much is bad because you loose the accuracy of the recording. You are sitting right up close next to the speakers and you want to hear the music accurately from the speakers, not the walls.
