HowdyPardon my ramble, but bear with me:
I have way too much gain in my system in that I can turn it up about 30dB louder than too loud, however this allows me to hear the noise earlier in my system pretty well if I pause my sources or (carefully) use a track with extremely low levels. When I turn my system to full volume and invite my wife or daughter to listen right at the tweeters I have just a minute amount of white noise so I'm guessing that my unshielded cables are doing great at reducing the noise pickup in my system. (I have in the past had much more colored noise under these circumstances and have explicitly addressed the issues so uncovered.)
Every type of shield I've used (from very small amounts of ESR paper to cables with a little graphite to cables with more, to explicitly shielded cables to coax for speaker wire, etc.) all mess at least with the macro and micro dynamics of the music and with the overall coherence if not also explicitly rolling of the highs loosing air, etc.
Don't get me wrong: I know that there are a lot of systems which are quite sensitive to RFI, EMI, that are microphonic in various places (including their cables) and that almost everyone of your posts is correct when talking about those systems.
However there are also systems that are better designed which are less sensitive to these forms of interference, still are resolving and detailed and yet are very engaging. Hence I think that at times you overgeneralize.
I have no qualms saying my system is one such system because I can hear differences in cables, mechanical isolation, power cords, etc. as well as that I've visited many other people's houses, shows, etc. and can comfortably say that with the exception of one other inmate's system (and then only sometimes) mine has the most resolution I've heard.
This is in part why I've invited you over on the past (tho I know that most people don't have the time or inclination to visit a pig in a poke system :) One reason is that it's always fun to have visitors (and to visit others) and another is that it's always fun to see how other paths lead to systems that are just as enjoyable as our own.
I'm not claiming my system is perfect, far from it. But most of your posts (tho correct for many systems I've encountered) are so far off of the mark for a few systems I've encountered that I have to speak up now and then :)
