Tom from SVS has me doing the usual. Use a different cable, try a different outlet (actually my idea), but of course if the problem was a pure fluke, I am wasting my time. Of course, if the sub does it again, then it localizes it (somewhat) to the sub or the receiver (which is powered of... OK, in standby mode like all receivers).

This could be a long process until the problem happens again...
