Sound quality comparison of sapphire and diamond stylus at VANROCK Vinyl Record Cutting Lathes

I compared the difference in sound quality of three patterns with and without two styli and a heating tool.

Thanks for this, its surprisingly hard to find stylus audio comparisons on youtube

[@Not-Only-Reaper-Tutorials]

Interesting ... when you took away the tonearm, the surface noise continued ...

[@Vansix_Lathe_Store]

Sound is recorded separately from the video.

Cool

[@DJKOJI-jl4wq]

That's it awesome😆😆😆

[@Vansix_Lathe_Store]

I will upload more verification videos in the future.

[@DJKOJI-jl4wq]

@@Vansix_Lathe_Store I think it's a really interesting attempt. It looks like retro equipment. I like to see machines that dig vinyl grooves, so please continue to show me various things in the future. Thank you😊😊😊

Vinyl snobs will HATE this!

[@Vansix_Lathe_Store]

Could you be more specific?

[@gunier.j.kintgenanimations]

@@Vansix_Lathe_Store Oh, Sorry! I was thinking that they'll have a hissy fit over the fact that the tracks are going into the center of the record, & the negligible frequency loss will make the whole experiment null & void.

[@Vansix_Lathe_Store]

@@gunier.j.kintgenanimations That is why it has been proven that the sound quality is better with heating tools.

[@grustlesimmons]

what if the audio is processed ( RIAA EQing) may fix the audio muffled with the diamond stylus and heating tool?

[@Vansix_Lathe_Store]

Are you saying that the sound is more muffled when you use it than when you don't? If so, are you applying too much temperature?

[@intell2OOO]

seems like sapphire is chopped, you need to inspect it under microscope

[@Vansix_Lathe_Store]

Of course I have a microscope, but don't bother looking at a 40 year old sapphire stylus.

[@taranagnew436]

does the styluses affect bt sound quality like on speakers?

[@Vansix_Lathe_Store]

I do not think there is any effect of stylus differences because the differences in sound sources are reflected in the stylus.

[@kencekosh2127]

Can my sapphire be resharpened?

[@Vansix_Lathe_Store]

I am sorry. I do not support resharpening of sapphires.
