Very true. The 'worst of the worst' seem to be the 5.1, 6.1 and 7.1
Surround Sound systems that folks add on to their big-screen TV's. The
speaker cables that come standard all seem to be about a quarter wave on 20
meters, and on my own system before I added ferrites on the leads, I could
blast myself out of the room with 100 Watts on 20. Ferrites on all the
leads going in and out of the box fixed the problem 100%, even at 1.5 kW.
