Manufacturers with great customer service

Before Parasound was sold I called the 800 number and a gentleman answered 

I said my JC2 volume know will no longer move. He said send it in we will fix it no cost 

That was it.  Great experience.  Word is that’s all changed now

too bad 

Unless you bought used or factory direct, its the dealers responsibility to provide you with good customer service. People always forget that. You're not shopping in BestBuy. For the money you spend on this stuff, and the dealers almost always have a protected area just for them, its expected that they should be the one to help when you have a problem.

If you have to deal with a company directly, most are OK. Its not a high volume business and if a manufacturer gets a bad reputation for customer service, it could put them out of business. If you have a piece that's out of warranty, call them anyway. As long as its nothing extreme, they'll usually fix it for free.

The only company I can think of that stands out as having bad service, is B&W.

VPI for sure.

Veritas Cables

DH Labs Cables

Cambridge Audio US ...

Almost of all of them I have dealed with.

Innuos!, great customer support.  I bought a Pulse Mini used and discovered that the little LED that shines down from under the faceplate, when the unit is on, was not working.  I contacted Innuos and they sent me a replacement mini circuit board that housed the LED and the on switch with the instructions to replace it.  I got it free of charge from Portugal in less than a week!  That’s outstanding customer service!
