It might be just me but after changing from 5.1 to 5.1.4, I don’t need center spread turned on for DSU on 2ch music anymore. Maybe it just balances better this way when heights are in use. \n\nAnd I still think NeuralX has a little too heavy of center channel use on 2ch music upmixing.\n\nYeah nothing's perfect. NeuralX works better for some, DSU works better for some. But they are both a lot better than their predecessors.
