Tubes and TVs

I have a very confined situation in which my amp is probably going to "have" to reside near( a shelf below) the tv in a armoire type cabinet. I havent committed to tubes just yet, but am leaning that way to match Proacs i recently acquired. The question i have is, are tubes more prone to tv/tube interference issues vs. solid state in this unfortunate setup? (the tv currently crt) Do lcd or plasma have less "interference issues" than a crt. Are there any suggestions for further creating a "separation" or electronic barrier between the two? I am probably going to run the tv/cable wiring a good 2-3feet apart from the component cables/line conditioner/speaker cable to start some sort of isolation. Any further insight would be greatly appreciated.
