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! It's been over a month since i submited a Q! I am stll e-mailing the question...i am sort of amused by now!
Talon Audio has been great. They are always accesible, willing to stay on the phone and answer all your questions, and are very helpful.
Castle Acoustics in the UK answered all of my questions via email regarding the crossover specs of my speakers quickly and accurately. Their US rep. May Audio Marketing was also great to deal with, and supplied some of the best customer service that I have ever encountered in any industry. Kevin Walsh at Homegrown Audio is one of the best as well as Craig at Vibrapods. I am an hours drive from Upscale Audio and cannot wait to visit their shop when I look into a small SET setup for our spare bedroom, based on the feedback that I have seen posted at this sight.
I haven't had any bad experiences with customer service from high end product manufacturers. I have had EXCELLENT service from Audio Research, Nordost, and McCormack (steve himself!). Couldn't have been better. Definitely several cuts above the mass-market conglomerate producers. It was such a nice surprise to call and actually talk to excellent technical people.
