Hi,

One thing is for sure: Once you have either one of these devices in front of
your K3 receiver, you can wave good-bye to the world class blocking and IMD
dynamic range of your receiver. I would consider this an absolute last
resort. I don't think I could put up with the necessary knob twiddling
required to locate the null, which will change each time you change
frequency. So far as I cane tell no noisy plasma TVs in my neighborhood -
knock on wood. Everyone in my family is happy with our 40" Sony LCD TV
(which is quiet) so no pressure there.
