How would you go about testing the before and after of any- if any- improvements

Don't know about others but I can judge them by texture and smell.

I am just posting something I am trying. I am not selling or 'reviewing' anything. I suggest if you are interested, try something, if not, then don't.
If you don't like the smell... why are you rolling in it anyway?

Sorry to see this thread decompose. But on the off chance that you're still looking in here, Beet Farmer, here's a butcher-block/vibration-control combination that floats my laptop's boat, sonic-wise. I submit it solely as a conceptual example, since the pictured Final Labs Daruma ball-bearing-based footers are years out of production.



Having over the last few days listened to various configurations--e.g., the laptop mounted on Aurios footers alone, on a 2"-thick maple butcher block alone, on the Darumas alone, and, finally atop the Darumas mated to the butcher block--the latter combination (the one pictured) gives my ears the best balance of transparency, instrumental and vocal definition, and freedom from extraneous artifacts that render the musical presentation either too bright or too "soft".

I assume that what applies here to the laptop in terms of vibration control and the sonic payoff--namely, combining a butcher block with appropriate under-chassis footers--is similarly applicable to program sources such as CD players or turntables, and perhaps DACs. But since this is something I've tested only in a system I know, your mileage may vary.

For what it's worth.

Another application of butcher block. Or in my case, Boos Block. The cabinetry in my library is pretty, but wasn’t designed to provide the best support for my equipment. You can see in the photo my collection of “maple” which tightened up the sound nicely. I must say, however, the addition of Stillpoints Ultras under the P5 and PrimaLuna, and Minis under the Bryston and DAC helps [ATTACH]that maple sound that much better.

No political message intended. Just the picture I happened to have handy. It does, though, kinda look like Jim Acosta is stuck inside a giant oscilloscope with some fierce current running through his head

What do you guys think is better
Soft wood like cedar or hard wood like yellow pine or oak

Pine is a soft wood.

In all seriousness, the only way to tell is to experiment.

Various objects be they wood, plastic, metal, glass, granite, etc.. (glass is the worst as it would resonate at audible frequencies) will have some inherent resonant frequency. What we are trying to achieve here is for the object to absorb the vibrations caused by air pressure waves away from our playback system that are causing the gear to get excited.

Cheap stamped metal chassis plates will resonate at audible frequencies. Obviously the same frequencies we are trying to enjoy are causing the gear to vibrate at the same time. A chassis made of solid chunk of aluminum or other material that has been machined like some of the more expensive gear will not resonate at audible frequencies, hence will not add its own chassis resonance to the equation. Hence much less need for isolation platforms.

The key for any footer or platform is to absorb and shift the resonance away from the gear. So the solid state devices are not experiencing vibration. How that affects the sound is left to the interpreter, their ears and perhaps even imagination...

With tube gear it is much more clear cut. Tubes can and do add their sonic signature from vibrations, “microphonic”. Analog sources, that’s obvious. Solid state is not so clear...
