Manufacturers with great customer service

Burmester, they will service or update their products that are decades old and provide any answer that you might have. Pathos is also a company that goes far in providing great service 

Several: Rogue Audio, Ice Age Audio, Odyssey Audio, Innuos, DH Labs, Linear Tube Audio, and Apple.

The best ones are the those that you never have to get in contact with.

SVS.  Great customer service before, during and after the sale.  You can call and talk to a real live knowledgeable person.  I’ve had a positive customer service experience with Arendal too.  

Sota was great to deal with direct.   No problems,  I contacted them about an upgrade to my existing Sota.      It made more sense to trade up.  They made it super easy to get into a better table .   Good people over at Sota.
