I believe that CC is looking at DAS(AM) as an iHeart format that happens to also be parked on a heritage, now-borderline receivable AM frequency in Philly. As mentioned previously, the fidelity on the HD and more importantly the iHeart simulcast is quite good, and the format execution is world-class (and not an embarrassment to the format's history in Philly either).
I do believe that. 1480 will never be anything close to dominant, and would be lucky to get ratings regardless of format.
However, WDAS' current format is a nice addition to the IHeart platform, which is obviously trying to broaden their format offerings. And WDAS' stream sounds great. If it wasn't for IHeart, WDAS would be, at best, a jukebox in a closet, and a complete afterthought. Or it would be sold to some religious broadcaster.
