We have had good luck with the 528E's in all six of our stations. They work well for the Hard rock, Classic rock, Hispanic oldies and sports talk stations. Lately we have been playing with the 286S model with some success and a lot cheaper. It isn't as flexible and has limited range but a good product. I would not recomend it for hard processing, but for casual use it's fine. On the 528E's, we run most everything near the middle of the range and run heavier compression on our music stations and less on the talk stations. It has more that you can do with it. I don't like the de-ess portion but some of the folks like it. YMMV. As others have said, it's the mic that really counts. If the sound is not there, no processor can get it back. The RE20's are fine and the re27's better. Some of my "golden ear" types can't tell the difference between them and the Heil Pro 40 in side by side tests. The Pro 40 is much cheaper.
