Myrtle wood under TT

Not at all. The 3 blocks will creat a resonance dynamic plane under your TT. Thgis can only worsen nthe sound with harmful extraneous feild effects and sound wave cacelation. The only way to avoid these harmful effects is to decouple the arm and platter in such a way that both rest on a powerful bouyant mechanism. There is an example of one such device that will change nonasecond vibrations at many thousand Hz to ocean liner time reactions to waves actuallyb lower the speed of the insulting vibration to waves lowed down to at least .5 seconds.
These devices are available for about $8,000, Only about 4 times what my table cost, and must be adjusted with each record played. Using propietary knuckle busting inconvenient special tools. The result is nothing short of mind bogling. There was at least 2 threads about these platforms used mainly for industry.
If you want to spare yourself the expense then use old bilstien struts to support 1,000 year old cypess swamp wood burried in the deppest silt that is just dried enough to keep the stench down to a reasonably tolerable level. Make them using into hollow CEC precision cut cylinders.
Put these In side 512 and higher folded hand carved Damasus steel holding cups use shims to get a very tight fit. Inside the smelly cypress which a little ployurethane will seal in pretty good insert smaller sized silicon anatomic enhancing implants, which are not bused much and are always sold cheaply at surplus.
Be careful not to piecre them in anyway and these will never dry out.
Now those are as close to natures finest pillows as you can get. This is the only method that never fails to make any music you choose absolutely magical. The sound is just so organic feeling. And no--- bigger enhancers do not work nearly as well though however tempting.

Blueranger,given the price of the myrtle wood cubes, it doesn't make sense not to try them. We're talking about $30 at the most.
I can't tell you how something is going to sound in your system and neither can anyone else! Let your ears be your guide. You should know as well as anyone else that something can sound excellent in one system and sound like crap in another. Its about system synergy(mixing and matching components)to obtain desired sonics.
Having said that, I've tried and am currently using the myrtle cuboids with very good results. However, I'm using mine in conjunction with maple wood platforms and mapleshade isoblocks.
Ideally, turntables should be seperated from other components, not in the same rack/stand. Wall mount being much better than most other applications. If you cannot afford to, then try experimenting with other possibilities, some of which I just mentioned, thats the only way you'll know for sure.

To go even cheaper. Just go to your local lumber yard supply and check to see if they sell these. Can't imagine paying more than $2 per linear feet, if you happen to live on the west coast. These myrtle wood are produced in the Northwest states like Washington and Oregon. You could just buy a stick and cut them down to a few pieces...

Never put your turntable directly on wood. You want mass and a dead/damped material like stone, concrete or a layered material.

Pour your own concrete base with a homemade mold. Frame the sides with wood for a finished look.

I know you're low on cash, but my advice is to get a wall shelf if possible. They're about $150 new and the difference in isolation is huge. My dog jumps down off the couch and the record doesn't skip. You're going to tear your hair out and spend as much on blocks and other things that won't work. The cheapest way is to do it right the first time. Either that or get some very soft shoes.

Would my Diamond Racing pucks be the way to go??? I have 3 with cones under pre amp???? Mike

Second the shelf idea. Friend used chains and suspended a shelf anchored to the wall. So the back part of the shelf was bracketed and the chains supported the front part of the shelf and ran up and back to the wall. Isolated the unit well from foot fall.
