I have a set of Nari Ultimates. In synapse when I choose THX Spatial setting the sound is half as loud and sounds like crap. If I choose Stereo sound the volume is more respectable. THe effects "pop" with stereo buth with TXH sounds like I'm listening on a cheap bluetooth speaker you take to the beach or something. It didn't use to be this way. THX was awesome now it utter crap. I just uninstalled synapse and reinstalled and still the same.
