Back in the Dennis Had days, the customer service at Cary Audio Design was fantastic! There was gentleman named Kirk Owens working there who was absolutely great! He would answer any and all questions I had whenever I needed to call CAD on the phone. Once I even got the big man (Dennis) himself. Back in '20 I needed tech support, and getting a reply to an email was like pulling teeth, and forget about actually talking to a human on the phone (unlss you want to buy something). When I finally did get an email reply, basically what they told me was what their hourly rates were and instructions on shipping the amp. I actually found someone on another audio forum (AA) who helped me troubleshoot and repair which saved me literally hundreds of dollars (if not more). The customer service I got from Cary Audio in '20 may not be the worst out there, but it certainly was no where good as what CAD used to provide back in the '90s and early 20000s.
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!
