Roy,
You know where this is going...
No general skepticism! 
If you've heard it, and it didn't work, thats fine, let us know!
I'm a pretty skeptical on a lot of things in the audio world, and as much as I would like to run around saying: it costs $$$$ and its silly, etc, etc etc, it always spirals into the same useless argument. If you can provide backing (your ears, others ears, sceintific data, similar products, etc...) then I'm fine with it. I just don't want any personal skepticism with no true backing other than gut feeling. I should add that I have no problem with someone asking to understand how a product works. Questions are always (well generally...) okay.
Now, to be fair, I'm not sure your comment really crossed this line, it's borderline and phrased badly, but from now on lets just try and keep it a bit more 'factual'. Especially with that last sentence, you know you implying that the Purist Audio is more 'junk' than the IsoTek or does the same thing, and therefore not worth the extra $70. I understand what you saying, but since there is no backing, I would prefer to avoid statements like those. I hope you understand what I'm trying to say, nothing personal, but I just don't want to have to deal with this debate.

Edit: I went ahead and put this into my circle welcome post, so it should be more clear now.
