In MW mode most of the time, but some poor recordings sound better with MW off for me.
My MW is set to 3 as well.
I used 6 but that was because my amp’s transformer hum also went down with that setting. With the new p20 I will try again Monday and see.
Also using 6
I use 6 on my P-10 as my system makes so little demand on the P-10 that there is no reason to use any less! It sounds the best!
I am using 6 on my P12. Sounds great!
