Two main reasons. We wanted people that bought our product to be happy, (regardless of the price point) and we felt it was a good investment in our reputation and brand.
Vendors, retailers, and so forth gain points with me and some of you for going over and above, it's a wonderful thing. Not bootlicking over and above- but fair and accommodating to us and them.
I'm not an expert on anything per say. Just giving an opinion. Fwiw, our company has continued to grow and prosper over the past 27 years.
i am sorry you ended up with a bad deal for whatever reason. Hopefully the audio gods will smile down on you next go around!
Best,
Gary
