Interference : What to do...

After finding the source of some incessant ticking, much worse with the cans on, it seems I have a few options open

-Faraday cage, does what it says, not the easiest on the eye
-Tube shield, same concept as above, same pita...pite
-Relocating equipment (not ideal), heaps of wifi/visual gear...internally grounded, pffft. Not to mention hiding that tubey glow

Thoughts/opinions welcomed
