Audio problems on NBC?

Is it just me or my setup, or does NBC sound like it's coming out of a tin can this evening? I mean, it sounds like I set my TV up inside an echo chamber. It's not bad enough to make it unlistenable, just distracting as heck.

I'll reply with an answer to my own post. It was the network feed for "Heroes." I'm seeing many other responses on another board confirming that they too had it sound very echo-ey and tinny.
