CONFESSION - about cables and interconnects

Unscrupulous scientists do not invalidate the scientific method no matter how much MSM controlled by big corporations wants people to believe. Fossil fuel industry wants you to think that global heating is a scam. Plastic industry wants you to think that plastic can be recycled and that it IS being recycled on a mass scale. Electric car industry wants you to think that batteries that require lots of energy and resources and clean water to produce them while not offering a working recycling process are a solution to the world's transportation problems instead of working together with governments to develop public tansportation and local jobs. And so on and so forth. Counter-examples prove that some scientists are dishonest (a classic example was Edison claiming DC is better and less dangerous than AC), but do not prove that all scientists are dishonest.

And I tried to enlighten you as to your taking my post out of context. In addition, the reply you just made is nonresponsive to the point I made in the post that you only partially quoted. BTW if some of the methods you use are theoretical, how do you know that they have any real relevance to what you are trying to accomplish?

I think you just may be conflating science with technology, although they are integrated and do overlap.

What did i take out of context? I did not intend to. I just used the “quote” function to quote what you posted.

The theoretical methods that I used, Molecular Orbital calculations and Molecular Mechanics, were typically used to aid in interpreting photoemission spectral data. If the experimental and theoretical are in agreement, then there is greater confidence that the structure or mechanism one is trying to understand is correct. I never used theoretical methods without the corresponding experimental results. This is commonly done in scientific investigations.

I can give you a simple example. I collect some photoemission spectra on an unknown conformation that Ag nanoparticles form on the surface of a polymer. The data suggests there are 2 possible molecular conformations, a pyramidal and a planar. So I use Molecular Mechanics to optimize the 2 conformations in 3 dimensional space and plug that data into a Molecular Orbital calculation program. The program will than output the chemical states that exist for the two conformations. I take those states and overlay them with the experimental spectra to see which provides the best fit. In this case it was the pyramidal conformation. So i have good confidence that the structure is pyramidal. I might then use several other analytical techniques such as, IR, Surface Enhanced Raman, Static SIMS, Atomic Force Microscopy, to confirm this.

Thank you for sharing your experience with cables. I too have found a difference usually for the better . A very discerning hifi enthusiast friend told of his experience with power strips and higher grade AC outlets. I poo pooed the concept until I tried it. I found that the power amp did sound better when plugged directly into the wall outlet. I have tried and still use some very nice power outlet strips. But I always plug the power amp directly into the wall outlet. I also replace the outlets for my hifi gear with hospital grade types.
I did try a high end ( expensive) set of Aluminum speaker cables and they sounded horrible in my system , lamp cord was much better.

similarly, my entire system sounds better plugged into a Furman PRF18 conditioner, filter. i'm also a magic cable believer (full disclosure) but one of the biggest boosts to my SQ was feeding my streamer (first moving from a PC source to streamer) then replacing my wall wart powered hard drive, that was feeding FLAC files to my streamer, with a USB powered one. In my case, I boosted to a La Cie (Seagate's premium brand) 5tb ruggedized HD. From what I can surmise, getting the extra dirty power signature out of my path, made a huge difference, yielding blacker background, lower noise floor and more detail at every level.

It's the little tweaks the deliver the whole pic, between power mgmt, cables, source..

21st century voodoo, no wonder they call modern cities "concrete jungle". I suppose some acid or weed can clean those dirty bits even better.
 
if you shop smart and keep your eyes peeled, you can find signifcant values/

ex, US Audio Mart- I bought some DH Labs Revelation XLR and 2x22' DH Labs Q10 from a guy downsizing his AV system, for 20% of retail, in as new condition. the Revelation, between my DAC and Preamp, was a revelation and I may have even liked them better, feeding from Preamp to Amp but now they're feeding from DAC.

the uptick from some Kimber PBJ or DIY Duelund 16ga tinned copper RCA was palpable, with or without the afore mentioned drugs.

different cables make systems sound different. better or worse, is in the ear of the beholder but to say the earth is flat is just counter intuitive if you've already, first hand, seen the earth from space.

So are you saying your system sounded like garbage before the Revelation? I always get confused by how many revelations all these cables produce. You’d think after one or 2 the revelations wouldn’t be so amazing but then I keep reading about one after another.

You are confirming your "good confidence?"

Your final two paragraphs are what's known as jargon. I was once told by a Texas Instruments research engineer/scientist, who was into audio, that a researcher who cannot tell you what they are doing in lay terms in all probability does not have a clear understanding of what they are actually doing. What is it you are describing? What was the purpose of what you described?
