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?

@slaw and @geoffkait , agree with the concept of draining vibration from the component to a neutral platform. I must thank @geoffkait for turning me on to DH ceramic cones. I'm using them underneath SS and tube components. The points are sitting on a maple plinth with Herbies underneath. 
The result is focus, dynamics, transparency. Cones pointed up do not provide these benefits.

I was getting ready to post the same/similar words. 

Now, I just can't wait until I get my phono pre decoupled from the room....I expect greater things!

I discovered the positive effects of ceramic under tubed equipment a couple of months ago.It seems to work better than anything else I've experimented with.

I cannot disagree with the logic of cones down, HOWEVER as I stated in the OP, under my SS PH10 phono I could hear no difference.

So I am more intrigued by that as much as to why they work so well in present orientation on the tube phono.

@uberwaltz,

Tubes put out more tenny vibrations than SS in general. They are also more succeptable to taking on vibration from outside sources. A tube is a circuit encased in a glass enclosure. On (top) of that it's just out there, swaying in the wind...... think of a skyscraper and how much they move just because of their height, dealing with, as GK puts it, "Seismic vibrations" & wind etc...This all needs to either be tamed/drained/or both.
More to discover
