Best and Worst customer service?

Back in the 1980ies Snell sent me two new 10 inch woofers for my c2 mk 2 when only one was needing refoaming for 250! But my best story adcom I had their cd player it would skip and the big power amp which I inadvertently shorted out,  both units will out of warranty. They were located back then in New Brunswick NJ just 30 min from my house. I drove up and they fixed both at different times each time  for a dozen donuts. both the Adcom and Snells worked up to this day when I sadly sold them to afford newer and more contemporary offerings.  

Also would be remiss if I didn't mention Grado....  excellent customer service recently....let's just say they went above and beyond.

PURIST IS THE BEST SERVICE.

I’ll add a vote for Innuous. I was having a problem with my Zenith 3 and emailed them.  Got a response within a couple of hours requesting more details. I was then emailed by a technical person in London who asked about accessing my desktop pc.  I gave him access and he spent 90 minutes fixing the problem .  He also  gave me some tips about improving the sound quality (which already is excellent) and answered several other questions. I highly recommend Innuous products  for servers/streaming/burning CDs for the sound quality, features and customer support.  

A few years ago, I had a blown woofer on a NOLA speaker.  I called NOLA - Carl Marchisotto, the owner of the company, informed me that there were no replacement woofers available and then spent 20 minutes advising me of suitable woofers available from other companies which could be used as a replacement.  Truly impressive.
