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?

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!

I would definitely be finding a home/ use for those Stillpoints too.
Sounds like they are working well for you and that is what counts.
Coupling and decoupling at the same time may truly be the key.

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.

If there was something better I would have already designed it and be selling it. Whaddya think, Junior, these hands have been soaking in Ivory Liquid?

@geoffkait ,

Were you the other one in the van?

Although I’ve never tried them, the Synergistic Research MIG couplers...I find interesting. According to their literature, they recommend 2 down & 1 up or 1 up & 2 down.

@uberwaltz,

Those rubber/cork isolators were trapping vibes just waiting to get out. Those are mostly used for isolating heavy/noisy industrial equipment. The air handler for my HVAC system in my attic sits on 6 of them.
More to discover
