OP,
Amazing isn’t it?
I have two direct lines… one for my power conditioner and one for my amps. The power cord on my amps made a huge difference. Much more than the rest.
What is your system and venue? There is a place to show it under your UserID. Then you don’t have to repeatedly type in your system. It need not be “show photos”… but is great to see your system. Makes understanding much easier.
