Kevin Walsh at Homegrown Audio was extremely helpful when I purchased a used silverlace interconnect here at audiogon, and the ic turned out to be misrepresented and damaged. He sent me a replacement part for the rca connector free of charge and I didn't even buy the ic from him. A real stand up guy.
What companies have gone above and beyond?
I have had a few products back to the manufacturer for different reasons. Some companies have been fantastic to deal with while others have been a disappointment. Sota was so good I couldn't believe it. Aragon was almost as good. What companies have you dealt with that provided exceptional service?
