Shave your CDs

I think the more relevant issue is comparing the objective measurement with the "expert" reviews. Measurement=no difference

"Audiophile journalist=more transparency, pace, and other unmeasurable BS.

Does it discredit the reviewers or prove that we hear what we expect?

As a consumer who often has identified which components I will try to audition based on "credible" reviews that scares me!

Really works well on my digital files. Makes an MP3 sound as good as a FLAC file.

Well, the video was entertaining, but not real scientific. Things such as motor vibration, balancing the CD disc when being clamped, and most likely more, would yield different results. Ultimately, at some speed the event would happen.

 I don't know enough to say what effect that balancing a CD might have. Seems to me that it is better to have done than not. I did the same thinking with my grinding wheel by balancing them. Of course this is apples and bananas, yet for the grinding wheel things run much smoother, and the wheel grinds better.

 Vibration for just about any task is not wanted, unless you are trying to tear something up.
