I got the replacement 950 and unfortunately the popping is still there. For whatever reason the 950 is allergic to my set up.

While I was waiting for the replacement 950, I ordered a Sherwood Newcastle P-965 and set it up. It sounds excellent with my 7100 and it is extraordinarily quiet.

Outlaw customer service of course is top notch and I want to thank Steve especially for all of his help.
