Some manufacturers (Bat for example) allow you to easily swap absolute phase with the remote & others (Hagerman for example) give you manual switches to play with.
My take from playing with a BAT integrated I owned was that on most recordings keeping absolute phase 'correct' sounded subtly better and on one or two recordings (The Blues Brothers being a prime example)swapping absolute phase made a nice improvement.
I think a lot has to do with how well the recording studio does at keeping track of absolute phase in the mixing & recording processes.
FWIW, a dealer I know has a classical album that was recorded out of phase and you have to swap wires on one speaker only to get it to sound good, & I suspect that on many recordings some of the mixing is 'right' and some of the rest is 'wrong'.
