Best and Worst customer service?

Best Service: Modwright and Linear Tube Audio. These folks always go above and beyond when a customer is in need.

Worst Service: KR Audio (Tubes) no response about warranty issue.

Another vote for ModWright!
Great products and Dan is a great guy!

Pioneer - bad, bad, bad at providing technical support (There is NONE)

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

Best: Mark/Nick @ Rogue Audio,  Klaus @ Odyssey
Worst: Ty @ Tyler Acoustics (used to be good but something changed. Stated he will take my current linbrook sig for trade in, I was middle of a move so told him I'll let him know when I'm ready, then comes time to trade-in, says sorry I can't do it anymore as he wants to scale down. Way to stiff a customer that even bought his parents a set of his speakers b/c I liked them so much. 

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