I realize now that there are others like me who have not had too great an experience with Cary Audio. Some of you have had to deal with worse situations as compared to my hum issue. I realize that the dealer too is to be held accountable. But as a customer, I see the company and its dealer as a single entity. It is for them to communicate and sort it out with each other to resolve my issue.
I've been able to find a technician who is confident of eliminating the hum. I don't know at this stage whether it will cost me more or less than what i would have to pay to Cary. But, like I said earlier, it was never a matter of money.
