Yep does not leave, but I think it is the city transformer that is bad. I have very bad line noise in the past year, we are moving soon and that will resolve that issue Ivan.
But this still may help since I am sandwiched the 150 between amps etc. I am going to stage everything different in the next house. So maybe I will be OK.
I have thought about taking the MX150 to my girls house and a 601 just to test, but man that is a lot of work
I will book mark this thread thank you Ivan for the help!
