Ran across this in a thread on the NorthernSounds forum. The name of each piano library\vsti is announced and then the same portion of a piece is played. It is part of an ad for Proaudio Vault's own instrument, but PianoTeq sounds very good in this comparison. (No mention is made of which preset was used.) Notice that there are two mp3's, one for pp playing and one for forte playing:

A midi file was used to render the recordings, but in this case, that doesn't seem to be as much of a problem as on some previous comparisons.
