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?
Jeez guys
How on earth did my thread about ceramic cones under my phono stage morph into the Geoff and Sleepy show?
Wake up, Uber! I didn’t do nothin’. I stayed on topic and refrained from name calling. I’m only trying to help. 🤗 Deep six my stalker if you want to do something positive. Duh!
