Shave your CDs

Mho is the device doesn't spin fast enough nor have the 'edge accuracy' to completely promote the improvement possible, markered or not.

A higher rpm and a blade carrier that would introduce a more accurate edge bevel ought to make for a proper 'match' to the pit alignment of the cd's surface.

The arm of the unit is controlled by hand manually; cueing an LP by hand is almost unheard of at this time, so why would anyone want to 'lathe' a CD in this fashion.
May as well trade in all your gear for something with the 'Flintstone' trademark...

The only caveat would be to Not spin at too high of rpm's...it could have an unfortunate end, as these gentlemen are more than happy to demonstrate...

(This was done by seasoned professionals...who just happened to be out to lunch at the time...).

Don't knock it until you've given it a fair chance👆

umm, I don't know about this. I've heard of shaved ice and shaved  umm woodchuck but shaved CD's???

Do I save my CD's? of course I do.😆

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!
