I've got a way to use 4 different EQ presets. There's an auto RTA I can apply to the L&R channels together or separately and I can do the same manually to tie up all 4 positions. The point is that I can't tell my @ss from a hole in the ground regarding my preference. To me they all just sound ... different ... but only with certain parts of any given track ... with some parts of a track the presets sound very similar because the affected frequencies aren't being played.
This is gonna take up a lot of your time. Is this the basement system at the opposite end of the stairs?
Yep, that's me in the window.
