I'm glad you and a majority are happy (that's how it should be). The question is how a business handles normal repairs. Do they send it back in a timely manner? Do they make an effort to address the situation equitably?
I am not one to be litigous or be an asshole, I just want my repaired power amp unit back. If it was a big company, I could blame corporate greed or stupidity. However, my frustration has been that when respectfully asking for the status of my repair about once a month, half the time there is no response and the other half with "Sorry, had an issue with X, Y, Z. Will ship in one week."
Because I'm out almost a grand and a usable amp, it's frustrating. I'd rather up front honesty ("look we screwed up, let us compensate with x") than delaying games.
