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?

On a deadly serious note just where would the MD Springs reap the biggest benefit?
Under individual components, speakers or the complete rack assembly?

That’s weird, I just had my long explanation of MD springs deleted. What’s up with that? 
That is weird.
I had read it and saw nothing in it at all to warrant removal.
Wonder if Agon still having random post removal issues?
