What has happened to "the wife, spouse, significant other, who knows nothing about HiFi", but who used to pop their head around the corner (from the kitchen) and exclaim, "what have you done to the HiFi dear, it sounds so much better?" This usually followed some minor tweak.
Are our tweaks these days just not making any difference?

Now, no flaming please, leave the women out of this, will ya?
They only do this to please hubby, who after all would feel so guilty to have blown 1200$ on a freakin' cable...
audio-kraut. I was more thinking more along the lines that the wife probably never said anything of the sort, but the audiophile would claim this to prove that some tweak made a huge difference like, "if she can hear it, the difference is huge and I am not imagining it".

No it simply show that cables influence FR when used with real components, variation in FR obviously means variation in phase response also, the fancifull echoes are your mysterious issue.
Re: Loss of Information
You lose information with every stage a signal go through, the amount may vary depending on design and component quality. "Addition of unwanted stuff" is another matter but may, or will, also cause loss of information.
Loss of information start as soon as the soundwave leave the musical instrument, and seems to me the largest loss happen between the ears. 🙂

You do the math, and then see if you can make the outcome stand out of the picture.
As I stated earlier, what happens in a worst case scenario, does disappear in the big picture, simply due to the order of magnitude.
Besides, what diminishing small influence cables may have on the FR, is in the very top end of the spectrum, where it will drown in the fact that our hearing is not up to the task.
Find something of a reasonable scale, say 0.5dB (I'm being overly optimistic here, note that), which is happening below 18KHz, then we can discuss things further.
Till then, you're in conflict with basic physics, which doesn't leave you with much.

That's the problem, when you are concerned with detail it doesn't disappear in the big picture, it enhances the big picture.
Magura said:
FR is only one aspect and in this case I believe not the right place to look.

Maybe then it is time to use complex physics to understand a complex problem. 😀
useless psuedoinformation
not an offense at all... just some factual rebuttal of nonsense
then it's YOU who is wasting time posting in this thread... not even an accurate sidebar at that... your implied quantities don't make any sense

I didn't make up what I said. It's well known that even Lev Landau despaired there would never be any experimental data to back up his predictions regarding the nature of diamagnetism because of the difficulty in obtaining samples of bismuth and copper that were completely free of iron. You may think that I am wasting time, but your constant hectoring and off the top of your head science is completely worthless, not to mention the double posting.

Re: Re: Loss of Information
Absolutely correct.A few years ago,I was at a friend's house with another friend.We were about to listen to a LP he bought,with sounds of a whale recorded in the sea.A little before the track end,our friend asked when the sound of the whale will be heard.The other friend replied and told him :she has just left🙂
Magura:In general,differences and losses are possible through out the audible range not just hf.

Regarding speaker internal wire, between xo ond drivers
I made this 3way a long time ago
I used solid core
1 wire for tweeter
2 wire for midrange (now only 1 wire)
3wire for woofers
Now I have removed one wire on midrange
It has 1 wire now, and the same as tweeter
I made the change on one channel first, as I always do
It was clearly audible that with 1 wire it sounded much nicer
With 2 wires it sounded more grose and accentuated
Everything sounds much sweeter and natural now
Mind you again, this change was only done on mid drivers
Proof?
Its playing right here now

From further listening
I must say its quite an improvement
More fluend, airy, open and free of artefacts, better timing, coherent and sweet
Really nice
And thats just from removing one of two wires, nothing else
Seems a wire is not just a wire
Or at least, two paralel wires work differently that just a single wire

Re: Re: Re: Loss of Information
If you can prove that with just one single formula, that's based on physics, then why don't you?
It would put an end to this discussion right away.

I've measured LCR on three different IC cables:
Cable 1: 3.2uH, 69pf, 0.08 Ohm, coaxial copper.
Cable 2: 3.2uH, 74pf, 0.05 Ohm, coaxial copper.
Cable 3: 3.5uH, 85pf, 0.05 Ohm, twisted pair shielded.
Will these be close enough to use in a blind test to satisfy the 'same LCR' condition?

If your measurement is accurate, then yes. The values look too similar- you might check the calibration of the bridge.

tinitus, clearly you don't understand the situation, the larger the cable dia the better. Never trust your ears rather listen to your calculator. 🙂
