D'Agostino vs. Ayre

Your experience is contrary to mine. I've found Ayre customer service, Michael especially, to deliver exemplary service and support. I've owned Ayre back since the K-1, V-1 days. They have done several upgrades for me, given tech support over the phone, even provided a resistor change to increase the gain of my KX-R Twenty preamp. I'm Much more than satisfied with Ayre factory support.

@aardvarkbark  You are the only person I've heard ever make that complaint.  Ayre's service is second to none. I've called them many times and they've always been helfpful (and honest even when it's an answer they know I'm not going to want to hear).  In fact, I would say if you value service and a reasonably priced upgrade path for your expensive components, Ayre is the gold standard of the industry in that regard.

+1  Two sides to every story.  Customer from hell?

Yes, @aardvarkbark has made this complaint plenty of times on another forum. Sigh.
