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?

@three_easy_payments,

If you don’t mind my asking, how tall is the Symposium rack and what tt are you using?

Remember that acoustic "feedback" for lack of a better term, accentuates the vibrations components see. Is your floor a slab? If not, it should be braced underneath.

@slaw I fear I've hijacked this thread so hopefully no one is offended! The rack is 4 shelves, 36 inches tall.  I'm using a Kuzma Stabi S table.  The floor where the rack is located is not on a slab but is situated on a block connected to footer that is separating the basement from the adjacent crawl space and is remarkably stable.

@three_ easy_ payment,

Look at my virtual system page at my amp/rack support for an inexpensive/DIY solution. With the Stabi tt, it shouldn’t be an issue. Otherwise the Townshend products are great (based on what I read) and then there’s the Stillpoints stuff....................

Thanks...I'm checking out your set up and consider the options.  I see you're fan of Symposium and BDR as well.  Appreciate your time weighing in.

@three_easy_payments, look into the Townshend Audio Seismic Corners, which are designed to be used under the four legs of a stand, to decouple it from the floor.
