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?

Thanks for posting Elizabeth.
I find that very intriguing.
I presume by the pen blanks that would be something you obtain from a hobby shop?
Sounds like a cheap fun way of making some tuning adjustments with not a lot of cash outlay.

Thank you so much for the woodworking lessons! Seems I know not much about wood at all.
The links to the two sites are extremely useful.
Cocobolo is very well regarded by aftermarket turntable plinth manufacturers I know and now I see why quite so pricey.
However compared to some of the money I have wasted in the past a couple dozen pen blanks is not going to break the bank.
