Why does thx spatial audio software add echo?

I'm curious as to why thx spatial audio adds an echo/reverb to the sound. I don't know what it is supposed to add to the sound profile and thought this would be the best place to ask. Maybe to most it sound good, but to some it sounds weird. I was thinking to some people it could make it sound like its actually coming from speaking in a room and you can hear the echo off the walls. In the clip I have attached you can actually hear it make the electronic hi hat sound completely different. It also makes most music sound completely different than the original.
