Dedicated Stand for a Turntable ? Opinions.


Turntable stand that worked best for you.
What materials do you prefer and why ?
DIY guys are more then welcom to post their opinions.

Let me clarify.
I am going to modify Lenco 75 turntable. Besides building new plinth that will accommodate 2 phono arms which will be physically detached from the plinth on its own separate isolation platform, I am also going to incorporate a designated stand. I could probably get already finished product from one of a leading turntable stand manufactures, but I'm seriously thinking about building my own stand that will perform comparatively well with commercial stands and look as a part of turntable design ( a simple drawing is in my system- page ).

What building techniques and materials are suitable for such a project?
What difficulties can I encounter during a building process?
Is it worth a trial?
In your experience what design and materials did the trick?

WHAT DO YOU THINK?
My best experience has been with wall-mounted shelves, given that I typically have to deal with springy floors. I am currently using the Kuzma XL, which given its weight- approximately 177 lbs naked, does not easily mount to any wall I have in my listening room, nor is there a commercial wall shelf to my knowledge that will support it. (finite elemente allegedly made one, but as of about a year ago, that proved to be false).
I am now mounted on a very large, old chinese prayer table and use a large HRS platform beneath the table with some stragetically placed sorbothane 'chunks.' No footfall issues, dead as far as isolation goes. I had the big finite elemente floor stand designed for this table, with the special heavy duty top shelf, but could not overcome footfall problems and got rid of it.

Of course, if I had my druthers, it would be mounted to the wall somehow, but that is virtually impossible given my set-up.
I've looked into but have not constructed something similar to the SRA craz rack. Using solid center cut air dryed timbers with dovetail joinery, I priced out the cost of inserting titanium rods into each 4 legs and two cross members. Then injecting those tubes with a viscoelastic material. This is quite possible with very little "real" building knowledge.

Then I am planning on routering the edges of the inner top shelf, inserting aluminium brackets into each corner and threading stillpoints onto the brackets as they already have a threading possibility biolt into their bottoms.

On top of the stillpoints, I plan on placing a 3" piece of soapstone. This combo ought to effectively reduce footfall vibrations. The last part of the process which I have not figured out is what footers to use for the base of the table. Any suggestions welcome.

I priced this procedure out at just over a thousand with the stillpoints being the most exprensive part at around $300.
I tried a wall mount in an older house with good results, however,when I moved the walls were not great for drilling holes and I opted for the Clearaudio MontBlanc turntable stand. I use a Transrotor Apollon fully decked out, three motors and 80 mm platter with outstanding results. Vibrations or room acoustic feedback are the least of my problems with this setup. It has an acrylic shelf that sits atop a brushed stainless steel 3 pillar stand with cement or something heavy filled inside. Weighs almost 300 lbs I think. Add the 100 or so from the turntable and 400lbs of mass are on the floor.

The analogroom has one on display in San Jose. I have a pic of that stand in my sig picture gallery, Area 51.
