I have gone through two or three sets of grilles on my Thiels (they are cream colored and cannot be cleaned once soiled the least bit). The kind folks at Thiel go so far as to ship the replacements and bill me later every time. Very prompt and very interested in their customers. While I do not use their products much these days, Kimber has always responded to questions very quickly and intelligently. The Parts Connection staff have also proven prompt and courteous over the years.
Best and Worst customer service?
My vote goes for Sonic Frontiers, as Best! I was contacted within an hours, after e-mailing a question. Wery friendly and helpfull!(they can count me-in on the next purchase) Thw Worst? Linn audio!
