Stillpoints and reference-level speakers

Agear,
Your SOTA mechanically grounded listening room demands that the Backstage find a permanent home there.

I am so happy to see other members discovering and enjoying these Apprentice platforms. It is really a great day in this hobby when you can not only afford to buy an accessory, but it makes an important contribution to your enjoyment of reproduced music. I imagine that some of you, like myself just want to shout out to other members with systems great or small "Get these!"
I can't imagine a system that they would not improve.

While picking and choosing and auditioning new materials for the latest platforms this session appeared.

There was a variation.. of many tried that was less than 1/2 of 1 percent difference in gross material content. The presentation of this single platform was like having an animated 3D surreal Dali oil painting on the wall in front of me bending and blending itself onto the ceiling. It was if I were in a fish bowl looking around with double vision. While this vision within a vision was totally engaging it was also totally wrong. Strange how a little thing like chemistry can make for such a big change in sound. Speed propagation thru the material was the culprit. Tom. Star Sound Technologies.

Theaudiotweak, I haven't looked but is there a table of speed propagations through different materials? And what does one seek-faster or slower? Also is it frequency dependent? I had a good deal of engineering training in undergraduate school but mainly in EE and ME.

I have a table that can be used. The alloy I was seeing and hearing in "surround sound" had an additive that was a hardener to increase the wear characteristics. Great if you needed brakes for your race car but this one additive made for some crazy scenes. Less than one percent can make for some large differences so there was a long selection process and much listening to all the many concepts. Tom
