A Copernican View of the Turntable System

I can recommend floating the motor/platter in Jello. Dont knock it until you have tried it.
I found raspberry rather nice under the platter, but preferred melon fusion under the arm ( its a unipivot so it has eccentric taste ). My only concern is that I felt wild cherry opened up the bottom end on hard rock, but have settled for the more rounded and harmonically complete raspberry.
For my vintage Tannoys I found feather and down pillows fluffed up the sound just right. The trick is to place them asymmetrically to break up unwanted resonances.
For the amps, hydrogel works a treat. I used breast implants for a full and ripe sound. If you want the best the Tibreeze brand are excellent. These have a titanium coating but were discontinued in 2004 and are hard to find.
I'm still working on the cable solution at the moment.

My personal choice for isolation from ground hum is using cold coins below them. Best sound is from Krugerrands, 3 coins stacked, US Gold $ is next best, I can imagine that they have similar results below Direct Drives. YMMW of course

Hi Dgob,
Unless you have the turntable and armpods located on a solid wall-hung shelf.....structure-borne feedback is likely to be a problem.
Every suspended floor (even concrete ones) will suffer from this to some extent.
If I had to locate my TT on a floor-mounted rack....I would ensure that it was on an isolating platform like a Vibraplane of Minus K. Not sure about Dover's Jello however :-)
Your 'floating' plinth idea sounds like an attempt at similar isolation.
It should work to some degree depending on the severity of your structure-borne feedback problem?
Please let us know how you go with it?

Regards

Halcro -
Have to concur with the wall hung shelf. This is one of the best bang for the buck upgrades for TT's of all persuasions in my view and well worth the time and effort. Biggest difference I noticed was a cleaner and more transparent bottom end.

Dover,

Amen.
The audiophiles I really feel sorry for are those who live in modern high-rise apartment buildings like those in Singapore, Hong Kong, China and Australia.
Many of these are built using thin prestressed concrete slabs as the floors.
Being thin and 'stressed'.....these floors are similar to trampolines and are continually in a state of motion. If you put electronic instruments at various locations on these floors.....you can actually hear them 'singing' although most of the 'singing' is sub-sonic.
To make matters even worse........the dividing walls of these apartments are of often lightweight soundproof construction supported not on the wall below......but on the flexing thin prestressed slab.
This means that a wall-mounted shelf will be afflicted with the same structure-borne feedback issues as the floor itself?
