Manufacturers with great customer service

Others have mentioned coffee related items, and I will too.  About three years ago my home electrical system experienced  a severe episode of repetitive brownouts.  (The audio system wasn't affected, as it was off at the time and, in any case, is also connected to an AudioQuest power conditioner.) But my several-year-old  +/- $500. Baratza Vario coffee grinder was plugged into an outlet in the kitchen and took a hit. 

The morning after the brownouts I tried to grind my daily brew, but the grinder wasn't cooperating- the preset grind time functions wouldn't work, and to grind the beans I had to use the manual grind setting with my wrist watch serving as a timer.

I contacted Baratza and explained the problem.  The tech at Baratza surmised that the brownout had compromised a  capacitor on the power board deep in the innards of the machine.  He provided detailed instructions on how to access the power board and asked me photograph that component and send the pic to him.  The pic did reveal a small burned area on a capacitor.

A couple of days days later I got an email informing me that Baratza would send a new power board and instructions on installation.  The part arrived a few days later, and the machine has been performing flawlessly ever since. The cost?  Zip, zero, nada; no even for postage.  And all this in support of a customer with a machine that was many years out of warranty.

You just can't beat that level of customer support.  Baratza is owned by Breville Group Limited, an Australian company, and can count me as a customer for life.

I haven't rad through the responses but Atma-sphere definitely needs to be recognized for its customer service. I've been with them 25 years without a break and it has never wavered.

Pass Labs: I have only purchased used Pass equipment, but Pass Labs has provided support and advice beyond anything that I could have hoped for.

Linear Tube Audio: Quick response and willing to respond to all my requests.

Shunyata Research: I spoke with three different people there and received patient informative information each time.

Samsung

I bought one of their 3D TVs when they 1st came out.

A couple of small darker areas in the lower corners.

Remotely, they diagnosed a new screen was needed.

Just a few days later their rep shows up, big box, new screen. You gotta see how many separate pc boards he had to transfer from the back of the old screen to the new one. 

Amazing, done, perfect!

Sony,

4K allows bigger screens when you might be too close with older resolutions. I’m only 13’ from the screen.

So, I wanted a bigger screen, realized I wasn’t really using 3D, gave the Samsung 3D to my neice, decided to go all new Sony: TV; AVR; Blu-Ray.

Cable, HDMI, ARC channel; ..... Sony helped me on the phone, actually diagnosed a bad HDMI cable, get everything working from 1 remote, then got the cable box remote to control everything. 

Over the years, I do a reset of the AVR, and maybe call, out of warranty, but they help me anyway.
