Best and Worst customer service?

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

PURIST IS THE BEST SERVICE.

I’ll add a vote for Innuous. I was having a problem with my Zenith 3 and emailed them.  Got a response within a couple of hours requesting more details. I was then emailed by a technical person in London who asked about accessing my desktop pc.  I gave him access and he spent 90 minutes fixing the problem .  He also  gave me some tips about improving the sound quality (which already is excellent) and answered several other questions. I highly recommend Innuous products  for servers/streaming/burning CDs for the sound quality, features and customer support.  

A few years ago, I had a blown woofer on a NOLA speaker.  I called NOLA - Carl Marchisotto, the owner of the company, informed me that there were no replacement woofers available and then spent 20 minutes advising me of suitable woofers available from other companies which could be used as a replacement.  Truly impressive.  

The Worst-Nordost...had a 3m xlr ic Odin, bought at authorised dealer, wanted retermination (as stated on their site that is something they do) and after some e mail exchange (I still got those mails somewhere) they refused. 

Excellent service-Pathos....had an integrated amp. Pathos Inpol mk2, had a problem with power (switch) supply, send it to factory, got it back in better shape than it was before,cleaned, new tubes they even took care of some small cosmetic inperfections that were made during the use.

Aldo I had never had an Atmasphere product, I was considering once to buy sh preamps and mono blocks, wrote to R.Karlsen, got all the informations about those units that were on sale, he checked the data of my speakers as well, gave me some advice about it....
Needless to say, if the opportunity comes, will buy his products without a doubt...
