Over the last couple of days, I have been putting together a pair of granite isolation bases, for my Pre and Turntable
using 19 x 21 piece of granite and a set of Dayton audio ISO-4C cones.
I think they worked out fine.

Dude, your stuff looks lonely......but well supported. ;D

Great setup! :o
-
Wow!! Great set up you have!!
-
You've got some really nice equipment Brian! It mus sound excellent!
-
Granite gets enough of a bad rep as it is. You isolating it doesn't make things any better.
Kidding, kidding. That setup looks magnificent. Very cool!

Very cool Brian, matches the 7's stands nicely!

I do have some nice gear, and it does sound real nice.
The only thing I would change would be the cartridge, but I have not got a spare $3000.00
for an upgrade.

I must agree with you, every thing matches well and has helped with the vibration issue I was having.

And what would that be?

That is very nice.
Right now I just put my Rega P-5 on the glass base that came with a SunFire Amp. Under that I have blocks of Sorborthane. I am sure mine is isolated, but damn yours looks good.

I am looking at the Transfiguration Phoenix Cartridges. The problem is I have not heard one
this is a trade show demo, 50% off list so down to $1500.00

I was getting feedback thought my turntable at high volume (nearly the same volume as Gary at CF)
That has stopped now, all I get is very loud music. ;D

I need to try that...my sub is too close to the turntable/rack resulting in horrible feedback. I can't use the sub with the turntable....

I had to move my sub across the room because I was getting a good amount of rubble on my Denon running a MC, but nothing like at CF. As stupid as it sounds, I made some blocks to sit my pre and amp on. I have a bunch of butcher block I used to build the base of my one turntable. I figured, why not cut up some pieces and put it under my components. Verdict is still out if it improves anything.

By time I made up my mind, the demo cartridge had sold.
Ended up purchasing a brand new one. here are some reviews.

I think it's the combination of the dead wight and the isolation cones, without the cones you still
have the same surface area for vibration to travel thought you should order some and try it out.

Since CF, put in a new audio rack and bought a bigger sub. http://www.definitivetech.com/Products/products.aspx?path=Subwoofers&productid=SuperCube%20Reference (http://www.definitivetech.com/Products/products.aspx?path=Subwoofers&productid=SuperCube%20Reference) . I made a place for the sub right under one side of the new rack. It has no effect on my TT. According to Rega, TTs need complete isolation, and they sell a wall mount to help accomplish that.
My system sits on a concrete floor. The thick Sorbothane completely isolates components from all but room vibrations created as I dance naked and sing too loudly.
The thick stuff is made for home construction in earthquake areas. You can find it on Amazon. It really tames a sub, or isolates any component. It looks kinda expensive until you try it. I buy the sheets and cut them into 1 inch squares. Here on the deck, it keeps my Polk MicroPro 4000 from ripping the deck from the house.
As to feedback, subs are prone to that. Run a separate power line if you have a big one.
