I thought I had a problem. It turned out to be one of my DIY power cables had a loose connection.
I did ship the amp back to Kentucky were it was run in for some time, tested, and I was promptly contacted. I subsequently found the cable problem and the amp was returned.
All in all the issue, or the lack of an issue, was communicated and handled very well. The VTA 180s have turned out to be an incredible fit in my system.
