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?

Pop quiz!


Are spikes couplers or decouplers?

Both, or either, depending on frequency. Decouplers above resonance, couplers at and below. A mechanical low-pass filter.

GK
So are you saying in your opinion by placing springs under my sub instead of the now spikes/cups I may find an even greater increase in SQ?
That would be a nice move if true.

I had thought about using springs under the subs for a while but since I already had the Stillpoints, why let that kind of investment just sit around? Additionally the Stillpoints are a ball n' cup device so from my understanding, the vibrations from above and below dissipate at the ball. IMO, this makes the Stillpoints both a coupler & decoupler.

Maybe overused by now but more mind boggling results.
Raised my little Denon au320 SUT up on 3 ceramic cones points downwards and probably an even larger SQ improvement than on the Chinook.
It is like a layer of grunge that I never even knew was there was just removed.
Clarity and detail just took a huge leap forward.
Makes you wonder just how much more is left hiding in those little grooves to be discovered.

I guess the transformer in this SUT was a pretty noisy beggar!

Sitting here with a massive grin from ear to ear!
More to discover
