What companies have gone above and beyond?

Conrad-Johnson did repairs under warranty to my amp that were neccesitated by tube failure when running aftermarket and NOS tubes they recommended against, for no charge. Thiel sent replacement drivers under warranty for ones that were damaged by my own carelessness in zapping them with high-level feedback, for no charge. Theta repaired my DAC under THE PREVIOUS OWNER'S warranty when it arrived with problems after he shipped it to me, still no charge. The high-end commonly offers a level of service that would be unthinkable in most industries where the profits are much, much bigger. We are lucky to be in a hobby with manufacturers such as these.

I will also add two names/companies to my earlier post: Both Mel Schilling of Camelot Technologies and Roger Sanders of InnerSound have been exceptionally helpful, forthcoming, and expansive concerning questions I have discussed with them via telephone and email. I would not anticipate problems for anyone dealing with these fine gentlemen's companies; they are available, concerned, and willing to give of their time and expertise. (I am sorry I cannot say the same about all the companies I have dealt with as of late, but that issue is addressed in other threads, and I will refrain from getting specific in this one, as no one else has allowed the bad to intrude on the good here.)
