I got a chance to test with the sub's high-pass filtering turned on, ie with the very low notes filtered out of the M2s. I cabled the sub in between pre-out and mains-in on the receiver (used to be driven from sub-out), so the sub's crossover could block out the LF from getting to the M2is.
"Mistral Wind" now sounds mighty fine at the same volume as before. Nice.
Not a huge difference but any track with active bass plus a delicate HF signal (ie most of the music I like
) worked a lot better with the volume cranked. It also sounds like something is a bit different acroos the freq range but I can't put my finger on it.
Had to slightly raise the subwoofer level, maybe to make up for the LF signal from the M2s ?
Looks like the PB1 has line out signals (although I couldn't find a pic of the connectors in the manual), not sure about the PB-10.
Have your M2s shown up yet ?
