Rogue Audio

I sent a Rogue power amp in for an upgrade and it got severely damaged on the return trip to me. Mark O'Brian  (of Rogue) sent me a new amp and I did not have to pay a penny. He was very nice about it.
Not a manufacturer, but Kevin Deal at Upscale Audio. I also second Vlad Bazelkov at Audio Mirror. And add Kara Chaffe of Dehavilland. Also Egglestonworks (speakers). I have dealt directly with all of these folks and the service was first-class, as expected. 
PS Audio and Pass Labs have impressed me greatly. Very responsive and clearly want to make sure you are happy as a user.
Bryston has been great.  Have never had a problem, but many questions and all answered quickly.
