My impression from talking with Peter, was that (hopefully) when (and not if) they fix the hiss issue, I would get a new one. No 30 day limit. Now, if I wanted to return it after 30 days for some other reason, I'd be out of luck.

But I also made sure that I talked with them *before* the 30 days was up, to let them know that I did have hiss, and that I could live with it for now as long as I knew that they would keep working on it, and that I would get a new unit when it was fixed. If that makes sense.
