Musicnoise, I'll be eager to read the results of your blind testing on your speaker isolation bases you plan on building (I'm sure you'll be posting it here)!

Seems any of us can be a bit inconsistent; after all, what evidence scientifically do you have that your home made isolation devices would result in improved sound over speaker spikes (In fact, I don't recall seeing much of ANY scientific studies on the efficacy of speaker stands)? Maybe you'd better start ripping on the speaker stand makers while you're at it. They're probably a bunch of crooks too. Maybe those sound isolation devices, and room tuning panel guys as well...
I'm thinking you'd have a really tough time distinguishing between the sound of your speakers in blind tests if they were set on spikes, carpeting or your supports. But, hey, if you believe your spring box device will work, GO for it!
You'd better watch that you get the absolutely correct rubber and wood; we wouldn't want a botched job due to poor materials!
It seems we all have our prejudices based on presumption. You presume cables cannot have efficacy, but that rubber and wood boxes do. And it's all happening in your head. Amazing what we can believe! :)
We don't really care to entertain any reports from you about improvements on the sound of your speaker springy things, or whatever you want to call them. We want real science. Your anecdotal report would be more akin to support for Yeti or UFOs! Really, I didn't think you were such an anti-scientific guy.
Sorry if I've been a bit sarcastic; couldn't help it. You're just a bit over-aggressive in this matter and someone has to call you on it!
Flyin2jz, it's amazing isn't it when you actually do the comparisons and hear it. No major scientific tests needed. The ears can tell quite easily the improvement. Yea, even "night and day."
One thing that is becoming clear to me through online discussions is that virtually no one has actually conducted comparisons between suites of cables. It seems that typically one cable is changed, one power cord, etc. No wonder so many give up or conclude cables have no effect. Between so-so systems, hearing problems, playing solely in the lower price brackets and similar constraints it's falling into place why people reach the wrong conclusions. Not to mention stubborn refusal to try based on distrust.
Now, I'll be very sincere. Musicnoise, I believe your home made box WILL work; it will make a discernible change in the sound. I do not think it is a foolish idea; however I do believe you should incorporate spikes with it for the ultimate isolation effect. I sincerely hope you will enjoy the difference, and I believe that you will hear it. Unless you will conduct actual blind tests, all you will have to show for it is the same anecdotal evidence persons like myself offer, which you have been mocking.
So, trust me, saying that cables make a difference isn't nearly as crazy as you think. Soon you may be joining us, albeit from the isolation device perspective.
