Z100 sounding great, agree. It's not my type of format, music wise but their Omnia.11 sounding great. And Z100 sounding what I miss in the sound of CBS FM. It sounding very thin, dry and flat. Q104.3 also. Stereo widening from CBS FM sounding nice, though and have that typical 80's touch in it. But I don't hear that in the overall sound. For a classic hits station with most of the time 80's you should have processing sounding like that, in my point of view. Like in the old days of Z100.
And I don't know what they done with the sound WBLS, it was for a couple of years ago the best sounding FM station in my point of view but it's also very thin, dry and flat. Don't now what they did.
