Tyron, I'm currently using the Athena Audition line (the original series). I have heard a few people say they don't like the sound, but I was impressed from the first note. And seven months after purchase, I still love my Athenas. Athena speakers are generally considered "best bang for the buck" speakers. They're generally high quality, but low in price. Certainly not the highest quality, but that would cost you several times the price of an Athena. Don't know about the interference with the plasma, but on their website, they don't mention magnetic shielding for the WS-60, but they do mention it for other Athena speakers. You may want to e-mail them to make sure it wasn't an oversight.
cheers,
