It occurs to me that the TD would also be great for ‘improving’ an instrument’s sound. To give an example, I did a rock recording a few months ago with a drummer whose cymbals were severely cracked, and therefore heavily lacking in the sustain department. While compression and EQ can do a lot to smooth and stretch out a dull, ‘broken’ instrument like that, I imagine the TD would be worlds better simply because it’s not level-dependant (as compression is), and therefore improves the sound whether the instrument is played gently or slammed to death, giving the perception of a ‘better’ instrument.
