As with JohnnyR, I believe your apparent lack of first-hand knowledge leads you to believe that meauring components is easy when it is not. Here is the paradigm for published audio component measurements I gave in my 2011 lecture to the Audio Engineering Society: In the final exam for my bachelor's degree more than 40 years ago, I was given a box with 2 terminals and was asked to determine what it was purely by measurement, using whatever test equipment I needed. Now while you state, perhaps dismissively, that "the bulk of participants on the DIY audio and Parts Express forums are carpenter novice dunces when it comes to electronics, electrical engineering, and acoustics," ask yourself if that were true, how well would any of those people do on such a test. But someone who can succeed on such a test of their skills is the only kind of person to who I would entrust to perform measurements.
And please note that you, GeorgeHolland, and JohnnyR, are conflating different criticisms. In this thead, the valid question was asked why I do not measure analog playback components. I answered that that is indeed something I would like to do, but that lack of resources make it not practicable. However, this explanation has now been taken as the reason why I don't measure cables, magic bowls, and tweaks, etc. This is incorrect. The reason I don't measure these things is because I am not sure what, if anything, should be measured.
I have said before that some of these tweaks actually have an effect, apparnetly repeatable, on the listener's perception, not the audio system. Measurement of a physical parameter is thus irrelevant.
In the case of cables, again this is something I examined in my AES lecture. As a result of the measurements I _have_ performed and my experience measuring audio components in general, I conjectured that the effect of cables, if not due to LCR, concerns differences in grounding and RF pickup/rejection, both of which produce small but audible changes in the character of the system noisefloor and its low-level linearity. Both of these effects are highly system-specific and in the case of RF, are beyond the capabilities of the test gear to which I have access. However, recent work by Ben Duncan and Martin Colloms has shown large measured differences in cables when it comes to RF pickup/rejection that, when you consider that in a feedback amplifier, the output port is also the input port to the feedback loop, that support my conjecture.

nt Fret..heh heh..they are Still singing Class A tunes all over the place I'm sure..I learned >BUy ThiS stuFF USED!!! if possable..I learned (THe HarD waY) when you build a system that makes you happy...freaking listen to it dont just wander into every new pc.of gear that gets reccomended. I learned how to pick things that work together because a really nicely put together modest system with a great synergy is better than IMHO a Class A System that you stare at and listen for this and that about the gear and how it blah blah..you know.. talking about gear WHILE the musics playing etc..."did you hear that!?" NO!!!...But I think I just heard..ThiS!> wow nice....:) glad we got it.(THEN).>OMG look at this pre-amp/speaker/amp/TT/Cart/cables,this IS what we need!! for years at great expense and even urmm...Greater STUPIDITY...ps: tho I dont believe there's any noob's to high end around here...if there are BEWARE OF ..ya ready.....TRADEING STUFF IN!!! dont do it nooooo I could kick my own A** for things I have lost because I was not Savy enough to realize that it NEVER ENDS!!! so beware of high end dealers and there "FAIR" trades...you will LOSE 95% of the time..over the years Mayan if I had kept all the stuff i got rid of.. I would have had Class A LOnnng time ago...hmm sounds familiar..I may write a song tonight..HA! oh yes..I would have saved & saved ,becuse I never should have got rid of literally MOst oF iT!! when it's musical to YOU,and has the goods as per YOU,..Unless ya have money flowing like water..(sweet)..where was I...OH.Just.build a nice system and be happy..and be sure any ANY changes to that foot tapping system you made are really something that will enhance your system... your musical satisfaction and NEVER change out a pc of gear just becuse you read it was good,,ya really have to listen to it in your home with a return policy or dont do it...Indeed I have bumbled so many good systems."hard way to learn" I can kinda get away with a very educated guess on what I need and what works well together..Anyways,.No matter how messy this stereophile site seems to be...I thank them ,I learned alot...I also want to say Please stereophile warn new comers to this wonderfull hobby..that it's only fair to be honest with the one's who stumble into it and go a little nuts and waste alot of money they could not really.afford..it happens.....and dont get drunk and rip your needle off the face of the earth of your beloved cartridge!! as I did with my Benz Lo-4 ..nice cart that was...the little Dyna 10x5 is a treat...like amazing for what 400$ pfft I've ripped the stylus off better ..>not "THAT" much better really...I dont miss my awesum?? sounding??..0_O stare at me I'm georgeous !Take my ToP offf BeBeee yeaH!> Mark Levinson #28 pre-amp damn how can something that frikkin awesum sounding and built soo sweet.... But>..wayyyyTTT!!! I hate this thing!!!! LMFAO...got a CJ pre after that phewww finally no more preamps for awhile..it's actualy been years the lil thing rocks...I bet you know which one I'm talking about with phono stage ..looks like a PV10B...oh..well yeah...it's clobbered many way more $$$ preamps at my house...not at everything but...MUSIC...yep clobbered even more $$ tube pre's that did other things better but not ...as endearingly musical ,tappin your foot just becuse the thing started tapping on it's own..." OMG this Band Rocks!" good...the music is what you NeeD To Be praising if your going to get exited and spew something out during listening..not the gear. ps:audiophiles I kust wanna say Mark Levinson is better than the preamp I bought just becuse it was a Mark Levinson..I just got stupid and even ignored a stereophile warning that kinda said what I found out..Gawd I really waNTED that Levinson..! dangit..whYYY WhYYYYYY!!!! I very much liked my #23 amp..yep I traded it....sigh...now I am comfortable in my gear I am making a change right now first one in years...relapse? nah I got a pair of B&W CM-9 dayam Bebeee look at me..take my Grills off..oh..I got 2 for teh price of one.so $1500 for a pair..couldn't resist:) the addict awakens!! and..my little tube amp will stay on my Green Mountain Audio Speakers..You think I talk alot Call "Roy" the designer of the Wonderfull Green Mountain Audio line.(better pack a lunch as they say)anyways.
