Ceramic insulator cone under phono stage shocker!

I have used small ceramic insulator cones underneath my phono stage for quite some time.
Previous phono was a Gold note ph10 and it did not make ANY audible difference I could detect which way up the cones were so I had left them cone upwards.

When I changed my phono to a Manley Chinook I just left the cones same way.
This afternoon I decided to flip them over so cone down just to see.

I honestly could not and cannot believe the difference!
I may have lost a smidge of low bass but everywhere else is improved in spades.
Much more detail, resolution, air, imaging, dynamics.
Just completely shocking how much better a small change has made.

But I am perplexed why such a huge change on the Chinook where I noted nothing on the ph10?

Any theories here?

Sort of like Tuneland
But without MG...
And a bit more cred.....

Wood you believe Iā€™m using something quite similar for the base of my new tiny little bowl acoustic resonators. I use crystal for the catalyst. I have a fondness for Gabon ebony, rosewood, walnut and maple. There is a fine line between resonance control and tuning.

One area I draw the line at though with any equipment tuning is removing casework or relocating power supplies, transformers etc.

Going to see if can find any larger chunks of wood as I do have a very good table saw in the workshop. Might be more cost effective.
