First WCBS-FM was using reverb (albeit incorrectly) and now the sound is about as dull and flat as AM radio. As if they are trying to recreate the sound of Musicradio77 WABC.
When I was active with the New York chapter of Society of Broadcast Engineers I was lucky enough to meet quite a few talented folks who knew their craft. It boils down to it either being an engineering decision or a programming decision. If it's indeed a programming decision then it's totally out of the hands of the engineers. If, on the other hand, it was a decision solely made by engineering, it's pretty sad - I simply can't (and don't) listen to it anymore.
As far as sounding like Musicradio77 WABC goes, I remember growing up listening to it as well as have plenty of airchecks at my disposal that seem to prove that even though WABC was an AM station that it had great audio. A nice bass thump (not quite on par with CKLW) and better than average processing. It's more of an insult to compare the way CBS-FM sounds like today to the way WABC sounded like in its MusicRadio heyday.
I know it sounded much better when Mike Erickson had his hand in it. Likewise, I had brought my own stash of processors when I worked at a couple of stations. Once time I even had a consultant tell me to pull my processors out of the line. I simply waited him out and when he left I put them back in during the next maintenance period. I think when Mike left they lost their golden ears.
