At KAAY I spent a lot of time listening to other stations. Sometimes to find jocks to hire, often to see what I could steal that was good. I always thought the reverb on the stations in Memphis was the best. Ours at KAAY was good, but Memphis always sounded better to me. I never met an engineer who had an ear for reverb and could do what they were doing in Memphis. Most engineers I encountered didn't want to use reverb.
One of the stations I would try to get airchecks on was WABC in New York.
Here is a link to some WABC airchecks:
