I wonder if the argument for using high level inputs is to have confidence that there isn't a delay between the low level signal going to the sub and the amp output going to mains etc... that can't be adjusted out with typical sub controls ?
Seems unlikely but not impossible... I see what appears to be interchangeable use of phase and delay when the two are actually only related at a specific frequency.
