Moving cables around killed dynamics for days anyone else experience this?

@paulcreed - It sounds as though audiozenology’s time in the audio business, mirrors my own, though I may have had opportunity, to have designed more live venues.      Something I did learn, in the over four decades spent professionally, in devotion to helping others better enjoy(or produce) their music(live or at home): While you can teach others how to listen more closely, no one/nothing can improve another’s aural acuity.      Picture attempting to teach a person, blind from birth, the color red.      The number of those involved in sound, encountered in those decades, that had absolutely no concept of sound quality, was an education.      Of course; their opinions/biases were based on their own abilities and- the level on Dunning- Kruger Effect they embraced.      No level of formal education(Degrees/certificates/certifications) can improves one’s hearing.      Bottom line: TRUST YOUR EARS and your own experience/experiments!

And some of us, like douglas_schoeder and myself, have been involved in the setup, design, and testing, of 100’s of audio systems, or maybe analyzed high hundreds of variants of audio products during the R&D phase (or both), and back it up with a solid technical background, keep up to date on related topics including psychoacoustics and developments in understanding human hearing and processing, and engage a broad technical community. Maybe we have been doing that for decades.

The evidence does not support your position. Trained listeners of no particular experience or skill, other than no hearing defects, are better able to detect differences than untrained listeners and though they want to think they are, most audiophiles are not trained listeners. One of the more successful training methods is rapid A/B switching to illustrate differences, something many audiophiles refuse to participate in.

In my experience, the people certain audiophiles make fun of, the ones you claim "can't hear", the "propeller heads", who have far more actual diverse experience with a variety of systems, not only can "hear", but understand far better what they are hearing and are much more likely to point out an issue if one exists. But feel free to keep believing what you want to believe. I know I am willing to test my claims day in and day out, but can others say the same?

That does not matter so much in this group where many of us like to listen, assess, and evaluate for ourselves within our own Music Reproduction Systems rather than follow you’re pronouncements which seem to often be based on intuition derived after reading a wikipedia entry or other basic source and why you would discourage anyone from conducting their own such evaluation may be is attributed to you’re fear of again being corrected for any of the patently false, misleading, and misinformed claims you have made hear. I have lost count of the times I have come here to correct you and when that happens you often make this claim:

" a troll is just a troll"

because you seem unable to accept corrections to you’re incomplete, inaccurate, and ignorant grasps of even elemental theories. And yet that does not stop you from proclaiming with self-appointed authority:

I am not "average", I am Superhuman!! My words have far more value than anyone else’s!

I made that a link to the actual page to remind other’s hear of you’re expertness! You have allso claimed a "moral authority" to post hear and I'm not even sure what that is about!

I recently purchased a new RCA interconnect cable from a buyer on E-Bay to go between my pre-amp and my amp. Reason for this is that I have identified that particular cable as a potential "weak link" in my system, and want to see how big of difference a new (better?) cable makes in the overall sound of my system. The existing cable is a $20 mono-price cable.

The cable arrived, I swapped it out, fired up the system, and immediately I could hear a negative impact compared to what my system sounded like before.  Bass was not as low, and the high's not as bright.

1) Based on what I have read in this thread, should I suffer through a week or so of listening to see if "burn in" of the new cable makes a difference? 

2) The new homemade e-bay cable was $20; shielded cable, quality end connectors, it looks like a good quality cable.

3) I'm tempted to purchase another cable, something a little pricier from a regarded cable manufacturer / supplier, someone that has a good return policy, so that I can try another cable and see what kind of difference it makes. 

So should all cable changes be given adequate time for burn-in before a cable's sound can be judged?
