I currently have the 8020D + 7040A. It's pretty much perfect sound with room correction applied, but the 7040A is kind of big and ugly. I'd be willing to give up some low-end to simplify the setup. Also the sub performs the crossover, so it's a lot of cords: 2 cords for DAC -> Sub, and 2 cords for sub -> L/R. And these cords have to be really long for when I raise my desk because the sub has to go on the floor.
