Scott,
That is another story.
Testing cables microphonics (in fact equipment too) can be interesting.
Turntables can be very microphonic.
My last turntable had a weight of nearly 40Kg, it's stand, sand filled was another 100Kg, I had a multilayer damping sort of platform weighting another 25Kg or so. The whole platform was string suspended.
The only possible path for microphonics where directly through the vinyl, which was clamped and all.
I still could easily get full acoustic feedback (very low frequency, due to the RIAA and the Arm resonance) with my corner loaded 15" Tannoys, but I would never listen at the levels this needed set on the volume control.
However, here we where before debating the microphonics of a Preamp.

Hi,
No, it is sniping both way.
However, try finding any thread that disintegrated into a objectivist vs. subjectivist that started with a subjectivist attacking objectivist positions.
Or show me one where objectivists debate their beloved measurements and a subjectivist butt's in sniping (me excluded, I have picked this tactic simply because someone needs to hold up the mirrors) rubbishing all that is debated with a "but it does not matter because I hear different" fell swoop?
The point is that there is a militant and puritan streak especially evident in some US based contributors that denies the validity of any position different to theirs and attempts anything to deny such opinions and positions to remain standing, but will do to suppress or at least discredit such. And these attempts do often take forms that certainly can be taken personal (in fact, they would often do Senator McCarthy and his Committee proud).
Do you really expect the other side to meekly take it all on their knees and ask forgiveness for their errors, like in a communist showtrial?
Now sticks and stones and all, but I can assure I do not take gentle to be pushed and if you push me, expect for me to not be like Gandhi, expect an echo, with amplification. I by far more subscribe to von Clausewitz on strategy and Robert Anthony Wilson on tactics, though I greatly admire Gandhiji.
I have always championed the view that different viewpoints and different world-views can co-exist and when engaged in honest exchange, can enrich both sides. In fact, as Sun Zsu said, "The wise man gains much benefit from his enemies, while the fool gains non from his friends.". I gain much benefit from those that constantly try to detract with obvious lack of grace and intelligence, I doubt they gained much from me...

What I regret is the clear censoring of valid questions.
Example: Designer X builds an amp case from Mid Italian Puzzuoli Marble and gets an A rating and sells like fresh BLT sandwiches. Designer X proceeds to pronounce that this proves that amp cases from Mid Italian Puzzuoli Marble improve the sound.
I think we all can see the fallacy of this reasoning. Coincidence is not causality. Yet when I ask a question or state an opinion about that, X and his groupies fall all over me as if I am about to torture, kill and maim X. Why? Maybe there is something about Mid Italian Puzzuoli Marble I'm not aware of. Or mayber designer X has no idea either, but then he can just say so, no?
What's the use of having all these high-powered people on-line if you can't ask a factual question without being cut down? Designer X could teach us so much, yet all he does is cloud the issues and and spread misinformation. I'm really getting sick of it.

PS If your foot fits the shoe, it's probably yours.
Hi Patrick.As someone who makes a living positioning 100kg objects to picometers by magnetic levitation,
I guess I have had my conclusions on these things years ago.
Patrick
How did you measure picometers?
Cheers, John
Just wanted to let you guys know I am watching. Let's keep it about ideas and not personalities.
Jan,
A refusal to answer certain (parts of) questions may be a result of signed NDA's with stipulated penalties or a feeling that it encroaches on what one considers "bread & butter" stuff.
I had on several occasions outraged e-mails on how I could just so freely post the "inner secrets" of how stuff can be made to work properly from other designers and not just from a single one!!!
I think this will remain like this, until we live in an ideal communist society where all share freely all they have and all they know for the betterment of all.
In the meantime, would you personally like volunteer in a legally reliably binding way (mean putting up a sizeable cash bond) to pay my (and "Designer X's") legal fees and any penalties awarded and the loss of income in exchange for me freely answering your questions? I think 500K Euro should do as a cash bond, but I would have to double check to be sure of minimum amounts. I think the NDA from that DAC chip making company I cannot mention alone may need most of that.
I support the concept that information should be free, in both the sense of "free speech" and "free beer", but last time I went down to the Pub the Landlord had not yet heard of the "Free Beer"...
This one seems to fit yours, I just wonder how that big hole got there...
Do you shoot yourself in the foot often?

Someone here did that stuff on a military grant at a now defunct startup. I'll have to ask him. BTW got my 5lb. of bismuth.
You can just say that you don't answer the question. Not the same as attacking the questioner because he questions.
You DID read and understand my post, presumably?

It seems to me that if you know something but you can't say (e.g. because of an NDA) then the wise thing is to do both of the following:
1. don't say what you know
2. don't say that you know something that you can't say
To do anything else is frustrating for the rest of us. It is not possible to have a fruitful conversation when some people claim to have superior knowledge, but then can't say what it is. It would be better to just keep quiet, and smile to yourself about the ignorance of others. This is, after all, a DIY site so I would expect people with commercial interests to only talk about things where they can talk freely and are happy to talk freely.
Regarding subjectivist vs objectivist arguments, I don't think we can simply assume that these are different planets. If someone is advising a newbie and says something which I believe to be untrue/daft, should I correct it or should I tell myself "That was a comment from the other planet. On that planet it is true."? Having said that, if a newbie gives me the impression that he is looking for advice from the other planet only then I will usually stay silent - hard though I find this. Sometimes I will admit to losing self-control and making a comment. Perhaps it would be better if people were clearer about what they are saying/asking: general claim/question or personal observation/recommendation?

Jan,
I believe I do that. And I do think based on what I have read from John and Charles they answer to that point (and often past that) and when they do refuse they get beaten up for not telling...
Steve Eddy meanwhile demands that those who are not willing to give all they know for free (including stuff they signed NDA's for and are liable to penalties) should just shut up completely.
I will seriously consider his advise.

First you need to figure out what your resonant frequencies are as that will determine the most effective material to use.
