IJ,
Several recordings which are pretty common members of people's libraries are
Nojima Plays Liszt, 1987 Reference Recordings
If you have this try track 2 La Campanella. I identified two spots where I think this is pretty pronounced; from 45-55 secs then from 1:30-1:45 seconds. However, the problem is sprinkled throughout this track.
Even more common in everyone's library is Patricia Barber NightClub, Track 1, bye-bye blackbird, during the long stretch of piano solo - listen to the segment from 2:35-2:48.
Another example: the Earwitness Transcriptions distributed by Madrigal Labs. Steinway Reproducing Piano. Disc one, track one Padereski plays Paderewski: Caprice Op.14 No.3 in G. Listen to the piano trills between 12-14 secs. The trills above and below these in frequency a bit further on are all clean and natural. However the trills between 12-14 seconds make my teeth resonate.
All three of these discs presented the same unpleasantness on the two entirely different systems that I listened to. Perhaps the one thread that tied these two systems together is that they retail for about the same amount of money.
