They are door stops from HomeDepot @2.99 for (2) only come in white though. I may change these to cones later$$. Cost was an issue with my decision. The whole project cost $10.:thmbsp:
Thanks,
John.
No, not cones, door stops, furniture button, sand, lead shot, or brass footers....sheesh!
12" or 16" inner tube.....I'm telling ya, this is really what you want to use.

Be sure to read all of it, including JoeE's experiences.
Also, there is a TON of material on this subject in the Steve Hoffman Music audio hardware forum. Industry sound engineer Barry Diament has been recommending this for some time now. Just search for "inner tube".

Tubes & Klipsch!
Ok, ready to report. Went to Lowes today and got an 18" x 18" x 1/2" piece of granite tile. Then went to Wally World and got a 16" inner tube. Well, all I can say is this is the best $15.00 I have spent on my system. Dead silent. Cranked it up and, who, what a differance! You guys can keep the sand!
Thanks for the Tips!
I'll try to get a shot of the set up posted asap.
Thanks Puma!

I won't say I told ya so, but... 
The granite tile is too massive, really.
Try it on a 3/4" or 1" plywood board. It needs to be low mass. This will make even more of an improvement.
Get some Shepherd 1 3/4" plastic concave furniture cups; see the posts where I showed pix of this earlier in this thread. Put a 1" or 25mm marble or ball bearing in three of the cups and rest your TT, pre amp, amp, CD player on these three arranged in an equilateral triangle. These "roller blocks" should be between your component on the plywood board sitting on the inner tube.
Get ready for a major improvement.

when revamping my thorens td-166, i built some additional isolation into it.
I made a new 3/4" mdf bottom cover, with four square mdf pieces added on all 4 corners, and those were bored out using a hole cutter, and in those holes I stuck squash balls as feet.
those feet stick out about 3/5ths of the way, and kinda flatten out a bit from the weight of the TT.
this is sitting on the top of my DIY sand filled flexi stand.
I'm sure I can get better isolation if I were so inclined, but these in combination work very well.
I can knock on the shelf the tt sits on, and not hear anything out of the speakers.
that, and it sounds great. there was a lot of improvement in comparison to a stock td-166
it looks good too.

Well, whadya say, Pilgrim
Every one of these solutions are subject to personal preference. While I'm sure that some are based on scientific calculations, the bottom line is how you perceive the sound. If you like the results of any given system, run with it.

My MCS 6700 table has some really nice shock absorbers in the feet that I think must have come with the unit standard. The thing is right next to a staircase with people walking up and down, and it hasn't missed a beat yet. If you can find one of these tables that isn't in working condition, tear 'em off!

that's my problem sometimes with the audiophile world. ie. if someone has spent £500 on a hi-fi rack then they are probably going to convince themselves there's a difference in sound when maybe there isn't.
At least with this tweak it's inexpensive and will be fun to see if I can detect any difference.

Not with the granite. It seems to level it's self. But Puma says I need to loose the granite and use 3/4" plywood. I'm on a slab, but I do know I can knock on the stand my TT is on and have no noticable sounds through the speakers now.

Where can I buy an inner tube? Target?
And wait a sec, don't I need to buy a pump for that?
Obviously, I don't own a bike.
