Incredible how much dynamics there is in this tread.
Never expected to be this an big issue and so many of you actually trying a lot of things.
So much information I have problems sorting it in my head, because this is quite new to me.
What I can tell so far is that Sorbothane is out
What I indeed didn't like about Sorbothane is that it isn't realy stable over time.
What I can also tell is that it is very important to use different materials. So use a mix of hard, dense and softer material. This is called "constrained layer design CLD ?
I remember I read a test of a turntable somewhere in the 90ies, think it was about the Townshend Rock Reference (not sure though) where it was said that a lot of research went into the use of combinations of materials (now knowing what Townshend knows about supports)
What I remembered, is that it is not only the use of different materials, but also in which way they are layed out.
Here comes acoustic impedance into place and how soundwaves transfers through the materials. (
@Folsom ) The part of acoustic reflexions on the edges of the adjacent materials was also a big part of that research.
A lot of thinking is to be done and you are all very helpfull in this.
Slate is the thing I allways wondered about. Although slate is a layered material in itself, it can be good. But when slapping it, my feeling says something else. With granite, even worse. Looking at the Peak Hifi SMD Acoustics plinths, these are more expensive than the SMD Acoustics Quartz plinth.
Quartz can be very good in my view as it consists of infinite little grains.
Someone with experience on the SMD Acoustic plinths? Or a link to it, could't find anything in the google...
@jeffrey_t do you have a link to the slate plinth?
Is Quartz Stone the same as Corian?
There is a lot of praise for Isodamp. Where to get it in Europe? I've only found a supplier in Norway. As I'm in Germany, maybe something a bit closer would be cool.
@Ovenmitt Yes it was your thread that initiated PeterA and me to start here. You have build such incredible pieces and unbelievable how much love in the details. You also tried different woods and their sounds. Thanx for all your input!
You find that bamboo works very good for you. That would also be great for me, as it is so easy to make it myself and don't have to supply it from somewhere.
Soapstone is also a nice material, could be good also.
Your seperate armpots make it also great to use different arms without changing the turntable with every change.
Would love to see more of what your findings will be!
Great pics, so one can see the multiply, mapleblock, steel plate, build on a profile. Are these materials glued together?
So theres a lot of thinking and experimenting coming to us. And maybe some links as to where to get these specific materials all over the world. I would love to get my materials from Europe.
As I actually listen to my system most of the time, I like some experiment, but this shouldn't be the biggest part of my life ;-)
I'm getting aware of something that happened lately: I build my own pre amp on basis of the Calvin Buffer (DIYaudio), Shunt PreReg, Muses Volume Control and big linear PSU. I had build it in a cardbord box and sounded incredible. I than build it in a good case in aluminium and it was more quiet and no hum at all, but it did sound quite different (not so good anymore)! I will use the knowledge from here to fine tune the sound from my pre amp.
