As those of you who have been following this thread know, I had been having erratic sound quality streaming Tidal. ATT came out last Monday morning and performed maintenance, replacing my modem/router, and returning everything to good working order. I was able to listen once on Mon/Tuesday, and twice yesterday and today for a total of six sessions and all my sessions have been very good. Apparently my modem/router was the most likely culprit according to my tech; the tech called back to check in on me today - good customer service on ATT's part. I do notice that my internet is faster now that the service has been performed and of course the most important part, the music is now correct.
Aurender has provided very good service along the way including providing me a loaner N10 and repairing my N10.
My dealer, Mike Rose @ Excel Audio in Newport Beach, has also been exemplary in his customer service. He had pushed me to have my internet connection checked and it turned out to be culprit. He has been there in my journey and has been instrumental in helping me to build a system that I had only dreamed of prior to meeting him around a year ago. As a totally satisfied customer, I suggest if you are in the Southern California area, Mike is a top-notch dealer worthy of doing business with, not only because he carries some of the finest world-class audio components available, but because he is first-class in customer service. Mike is just like all of us, he loves the music. When you are around him you can't help but be happy, it is just infectious.
