Manufacturers with great customer service

The folks at Rogue Audio were prompt, polite and spot on with advice.

ASR in Herborn, DE. & Bryston

I need to shout out to Steve & Willie at Krell service.  After bringing my units back to new, they freshened up my KCT pre, KPE reference and FPB300cx.  All 3 are like new for another 20 years.  And since I turn 70 today I'm hoping I get to enjoy then until the next refurbished when I'm 90. 

I haven't needed much help, but I've had really good service from McIntosh and PS Audio service.

For non-audio stuff, a big shout out to Bunn and Dyson.  I had a service need from both, didn't have a purchase receipt but in both cases I gave them the serial number and they both thought I'd made the purchase within the warranty period and sent me a new Bunn coffee make and battery form a vacuum cleaner!

Aric Audio, Coda, and Cerious Technologies. All three provide exceptional pre-sales and post-sales support.
