Audioquest 72v DBS problems with my DAC

Anyone had problems using 72v DBS Audioquest cables?

I was having problems with my Lumin U2 streamer, connected to my McIntosh MCD12000 SACD/Dac using a Diamond USB cable. Worked great for awhile then started cutting out randomly, shutting off and gradually occurred more frequently till it was not usable.

Lumin suggested using a Coax cable instead, I used cheap one I had and problem went away. So I bought a AQ Diamond Coax and problem came back immediately, cutting in and out. I unplugged the 72v DBS battery pack, problem went away immediately. Ever time I plug the 72v DBS pack back in, it cuts in and out immediately.

I've looked online and don't see anyone else having this issue....
