Manufacturers with great customer service

When I reached out to Spendor (A7s) inquiring about my room specs and potential integrated amplifier, they sent me a timely reply with some useful information and context, so thumbs up for Spendor.

Also, I wrote to Cambridge Audio regarding a question about the EQ in the StreamMagic app and they replied immediately with a helpful answer.   So, another vote for Cambridge Audio.

I have several Bryston components and their customer service was outstanding UNTIL they were acquired by a AXIOM in 2021.  I had an issue with my SP3 and sent it in for repair.  9 months later they finally repaired it.  Meantime the SVP who used to reply or call me back if I had questions NEVER returned any of my phone calls and emails inquiring.  After I was told by the only response from them told me they had lost my SP3!  The local stereo guru who knows and deals with them called and they responded to him.  A couple of months afterward I FINALLY received my SP3 back.  I will NEVER buy any new components only ones developed before the sale.  BE WARE!    Otherwise I can say that Wilson Audio has been consistently EXCELLENT responding quickly and very helpful.   

Modwright Instruments - repeatedly have provided great service and customer support for the last 10+ years.

Rockport speakers as well!
