Tattooed, I agree it seemed a bit much for one guy to have these issues on the only components I have owned from one manufacturer. It was frustrating at first because I have been a McIntosh guy for years and switching was hard. The new "dead" unit was almost enough to make me turn away. But I can honestly express that I am glad I stayed the course.
And dealing with ARC has been positive enough that I can appreciate that occasionally one get thru Quality Control although 3 for one customer seems excessive, I have to maybe examine my karma. In all the years of quite a few McIntosh units I think the only one I had issue with was bought used and that was the only used one I had bought. But they stepped up and repaired it at no cost. Funny thing was when I told them I bought it used, the Mc Rep asked if the unit was where I could look at it, I replied yes. He said to look closely at the front plate and see if if it said McIntosh, I said yes, he said send it to me here is your RA.
