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?

All three of these companies have been very good to me on customer service matters.

Sunfire - They replaced a Theater Grand II I bought with a brand new one with full warranty, when I bought it from a grey marketer who was pretending to be a certified dealer.

Legacy - They worked with me to get my Classics sounding good in my room, even though I bought them used.

Acoustic Zen - They did a repair on some of my cables without charge even though I bought them used.

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.)
Thiel not once but twice. No quetions ask,just send them back the bad speaker. What A great company.
Synergistic Research: outstanding for service & support! Recent experiences with their customer service are absolutely impressive! They've taken the time to work with me, address my specific needs, & answer my questions time after time. And when needed, even Mr. Ted Denney himself (the President) has generously shared his time with me on the phone on more than one occasion. Not only that, but they are genuinely interested in hearing feedback about a customer's experiences with their outstanding cable products. They follow through & make good on their word above & beyond all my expectations.
Admittedly quite some time ago, some have commented about not being as pleased with Synergistic as was expected. I would have to say that based upon numerous recent experiences, Synergistic has consistently stepped up their efforts regarding customer service & ensuring total satisfaction.
I am in no way associated with this company other than as a very satisfied customer, so I wanted to openly share that with everyone. And BTW if you haven't yet had the pleasure, although their previous product line was very good indeed the improvements made with the new X-series cable developments are significant, although their prices are essentially unchanged. I am very pleased indeed.
