Here is the update and it’s a surprising one:
Went to the dealer today with the MC8207 and right away I was taken upstairs to their tech department where they plugged this amp and the result was a dead quite none buzzing transformer and I mean dead quite not even a small buzz. Now I don’t know if their outlets have been treated since this is the tech department and not any other place in the store, it was the only place that we tested it. I was very surprised and happy at the same time knowing that this amp can be quite so I guess it leads me back to my house or the outside power.
I am in a search of somebody that really knows how to measure DC offset in the AC lines, I did what McIntosh told me to do and it returned 0.9mV which is nothing to make the transformer buzz but it could've been a wrong measurement.
As for the LED Lights that were not illuminating equal Left Side to Center to Right, there was a slight shift of an inside part that the tech had to open the front and fix it to make it all Illuminate the same, bear in mind this is a brand new amp and it needed to be open to be fixed.
I have already spoken to my electrician who is coming back to the house to do an extensive checking and we would be unplugging everything from the outlets and I mean everything, and will be turning off all the breakers off except the one for the amp and see if we can finally find the problem and if that doesn’t help than it would be the right time to call the electric company to do their part, because otherwise it would be very hard to convince them to come out just because I have a buzz.
I am a person that do not give up and would like to find a solution to fix this problem no matter what it takes as long as it is fixable.
And if anyone from here ever had to deal with their electric company would you be kind to share the steps taken to convince them to come out.
