For me TDR Nova works with both Wasapi and Asio.
I slightly prefer FabFilter Pro, but it's graphics won't play nice using it with MusicBee.
While an integrated one would be nice, it would probably be a big challenge to achieve the sound quality of these two.
What could be a nice compromise is having the option to place such 3d part equalisers in a panel or a tab instead of floating around.
