   Right, and as you have been repeatedly told, well above the range of the   
   human auditory system, and beyond the range of 99.9999% of vinyl records   
   ever made. Those few that do have some actual signal at 30+kHz are still   
   down in the noise, with distortion levels likely exceeding any actual   
   signal. Since nobody can hear it anyway, that last condition is fairly   
   irrelevant fortunately.
