Nope. the empeg doesn't understand the =replaygain= tags. but that's why you would need to either use something like foobar2000's diskwriter which can be set to honor the replaygain settings on output or modify the actual source file by the calculated value. If standardized volume (either 83 or 86 dB I think) is fine for you, you should just be able to run the files through wavgain using the per-track (radio) setting.
