Although my favorite local station (WRTI) streams their signal, their over the air signal sounds a lot better. I believe this is at least partially because it's not in MP3 format. Also, there are other local stations IMO worth listening to such as WKDU (Drexel Univ.) and WXPN (Univ. of PA). both stream over the internet and for both their over the air signals sound IMO significantly better than what is streamed.
