As far as modern pop/rock recordings go, "Morph the Cat", "Everything Must Go" and "Two Against Nature" are real good sounding, but compared to "Nightfly" or even "11 Tracks of Whack" they pale. If you download a track from "Morph" into a waveform editing program you'll see that in order to get the high overall level they heavily compressed and/or limited the signal. I don't know exactly how or what signal processor they used, but the effect is to sharply round off the signal peaks, especially the snare drum hits. It's not the gross distortion you get from going over digital full signal, but it is noticeable.
Regardless of the sound, "Morph the Cat" is a marvelous album. It makes me want to go the an airport and have my luggage checked.
