Best and Worst customer service?

Best customer service in my experience recently was Klipsch.  They could have just sent the diaphram and I would have been happy but they sent a new driver.   I know they are hard to reach sometimes  ut I contacted my dealer and I was up and running ASAP

Worst customer service?  Easy one to answer,  that would be VTL.  They would not honor their lifetime transferable warranty on an amp, rendering it a boat anchor.   Luke Manley is a P.O.S. and the most rude and arrogant person I have ever spoken to in my life.

STEALTH CABLES THE WORST COMANY WITH O RESALE IN THE USA STAY AWAY DUDES!!!!!!!!

Best: Roger Sanders
Worst: Kevin Deal

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.
