What companies have gone above and beyond?

I've been extremely happy with the technical support from Pass Labs and Balanced Audio Technologies. ARC is good too - though I feel they charge too much for parts.

For dealers (in Portland OR), I have received great service and advice from Jonathan Tinn of Chambers Audio (chambersaudio.com), and Kurt & Jim at Echo Audio (echohifi.com).

Sota and Eminent Technologies have both gone the extra mile.

Rogue,Virtual Dynamics, Klaus with his Odyssey Statos amp and Kevin@ Upscale Audio have all provided customer service that went above and beyond.

I have had excellent experience with Arwin from Classe in conjunction with Overture Audio.

Thiel stood behind twelve year old product. One would hope that nothing ever breaks. When it does, companies should try to emulate this company.
