i TOTALLY agree. the preamp in the Tampa is big, clear and clean. it does have a signature sound, but that sound is NOT "sizzly" in ANY sense of the word.
and ryan, what's with this "tube emulator" nonsense? there's no such thing in the Tampa. maybe you need to read your owners manual again.
i would DEFINITELY go with the Tampa over the ART/RNC combo. As chessrock said, the compressors in the two are completely different animals--but they're on the same "level". The preamp in the Tampa is FAR superior to the ART one. Everything i put into my Tampa comes out sounding very nice.
cheers,
