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.

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

Shout out to Chris Johnson at Parts Connexion......  Chris always goes out of his way to help.

Quicksilver has always been there for me...   super reliable, no problems .....just questions that Mike always answers promptly.     Their new headphone amp is quite good,  actually amazing for the money

That is amazing they would do that after a year.  I have purchased from them before , they were decent to deal with.   Your story says a lot about them.
