In anticipation of receiving my PB10, I notice that I'll now get a 180 degree phase dial, and not just the two-position switch on my sony. In the past, I 've used Avia to try to set the Phase on this, and basically, my wife and I just "agree" which setting seems to be better. Neither of us can experience the effects Avia is describing in the help text. It seems that in one setting, the lows and highsare a bit more distinct, so we use that setting. Is there a better way? Expecially since I'll now have many more options on the dial?
