I don't know much about McIntosh, but always thought they had a great reputation.
What you are describing isn't something that should be happening.
You have done everything correctly, and the issue persists, so it would seem the problem is equipment related.
The only other cause would be the power coming into your house.
Do you live in a rural area, or use your own power source?
Second, if you bought from a dealer, he/she should be by your side getting this rectified. Period.
I hate it when good people get the run around.
