Confirm i heard difference and voted for "Green". At same with vote i made the multiwire as a possible pollution for the little hardness and little grain which make the "Blue" bad. My experience is that direct link should be winner if not polluted no matter preamp is good (see my post http://www.diyaudio.com/forums/everything-else/245881-ultimate-listening-test-test-your-ears-audio-chain-31.html#post3709161).
I am a little sad because suddenly it became looking like a comercial and marketing for that preamp.

So do you think the multiwire is bad because of the skin effect or because the resistance would typically be higher than the solid wire. I know lower resistance connections can help reduce the impact of ground loops. Not sure which way the skin effect would have an impact.

Nonsense. I have not been selling anything in audio for 2 years, except for PCB boards for OPEN phono preamp project several month ago. I make living in another branch then audio.
I was expecting such reasoning. This preamp is not for sale, neither PCBs, nor kits, nor final products.
I was just interested in people's impressions, interestingly enough quite same as mine.
Time will tell you how wrong you are.
BTW: I am not responding to your suggestions on different wires absolutely intentionally.

I don't like to argue in cable subject, but experience/feelings is nice to hear and learn from and one can make trials in searching.
About skin effect, usual at least hot wire in signal cable is normal 0,5mm or less so all audio band arrive in recieving end under nearly same BAD condition and this is good because it is nearly equal bad conditions, trouble in 20Hz contra 20KHz impedance starts at thicker cores (speaker cables).
About resistence i am not sure but think mutiwire tend to have less resistence than solidcore, probably because of multi paralelling thin cores.
I don't think resistance and skin effect is so much reasons for different sound between the types. One thought is all those paralell multiwires do not bring signal at recieving end at same time (nano/microseconds) because of lack of precicion and cost, but have not science for this it is a thought. But if you have a DAW try on a track put multiple 8 or more micro delays (adjusted with small difference in delaytiming) on that track and listen.
To experience solidcore, listen to old recordings not bad.

When getting this information i apologize for the words about comercial and marketing stuff.
But look beneath it is like the book is written, and we are stuck. Think members just interested in learning for future.
I stop now, i mean first line, good evening.
To me, it has been a fact for more than 10 years. Above certain quality level, FFT says nothing. It only reveals huge faults.
..........You guys have still a lot to learn.
..........Time will tell you how wrong you are............

Guess you missed it. I have already revealed my vote and what I thought of the differences.heb1001, Max Headroom, a.wayne, Pano, BYRTT, please confirm that you heard differences and voted for green or blue.
I had already given mine, Blue, thought the green was too soft and not as real sounding as the blue..

Never got such impressions and so what if that was your intent , nothing wrong in testing the waters , the silly things people get bent out of shape over...

Well put ... for me, this is one of the key aspects for getting satisfying sound from audio. If the approach is to make the sound "laid back and soft" on less than optimum equipment, then what's happened is that the baby has been thrown out with the bathwater - the more that equipment is further "improved" the less there are real audible advantages to be heard, because the recorded material that makes the real difference to the subjective experience has effectively been discarded, well back in the chain. In one sense, this parallels the MP3 process - jettison some material, in the hifi world that which makes the sound 'unpleasant' - but then you're stuck with trying to make extra tasty material which lacks the complexity, the subtle ingredients, which are what the ear is looking for to make greater sense of what it's hearing.Agree The green was smoother than the blue, the blue had more dynamics and space around the instruments, i picked blue because i felt on a better system the hardness heard would not be present as it was on my desktop, the green was too laid back and soft ..
I sorted out the 'fatiguing' problem years ago, Jay - this is distortion, pure and simple. Not the nice, well-behaved THD behaviours, well trained doggies that obey every directive whenever someone chooses to call on them to make an appearance, so beloved by AP and the like users - totally obedient at all times. No, the 'fatiguing' stuff is nastier and harder to pin down - it comes and goes depending on all sorts of factors, it's "a very naughty boy!".Harder question (may have nothing to do with blind test) is: how critical is the “fatiguing” phenomenon? What will be the symptoms? Will and how this could possibly affect the deaf listeners? Can I make a circuit that is not fatiguing? Can this fatiguing aspect be quantified? What physical parameters are in effect?
Why, is it not even in your mind?
As far as I'm concerned this is the coalface in audio - no easy answers on what matters, and quite troublesome to fully quell ...
Thanks to a.wayne, Pano & BYRTT who confirm that they indeed heard differences & votes for green or blue. Gentlemen, please DO take part in the repeat ABC test when it happens.heb1001, Max Headroom, a.wayne, Pano, BYRTT, please confirm that you heard differences and voted for green or blue.
How about heb1001 & Max Headroom?
BYRTT, why don't you do your own poll testing your proposition that connecting wires make an audible difference? It's straightforward (though not easy) to do this. Make sure your levels match to much better than 0.1dB
You can test yourself first, then yourself again with foobarABX to check before you release the test to the public. I would be VERY interested in your results whatever the outcome.
BTW, the idea that a frequency response plot or a spectrum is sufficient is incorrect. They're necessary, though. I'd have no problem putting together a pair of files from DUTs that show identical distortion, level, and frequency response, but are 100% audibly different.
Would you email or PM me with how you would do this evil & secret pair of files? 😱Stuart, I'm interested in how you would do this. Can you tell us? Don't if it might be usable in our next evil test.

I'll let you think about it a bit.😀
I can imagine that something like a reverb effect could have low distortion and be set to have a flat frequency response, and yet be obviously audible.Stuart, I'm interested in how you would do this.

You right, if it wasn't for every equipment i have from Pc's to audio chains is in trial mode, you know temporary wires/PCBs and no cabinet tops

Stuart, I'm interested in how you would do this. Can you tell us? Don't if it might be usable in our next evil test.
I can think of one way, off the top of my head. Time reverse one of the files. A suitably complex allpass filter would be another way.

Nope, no file manipulation. Just changes in the DUT which do not affect frequency response, distortion, impulse response, or noise. The files are just recordings of the DUT output.
A suitably long digital delay wouldn't affect FR, distortion, IR or noise. But recordings of the output could be 100% different, depending on when they were made.
The interesting, 'real' data in the comments so far is that the people who clearly heard differences, without too much difficulty, are using the same language to describe the apparent, subjective impressions. Those 'skilled in the art' of reading between the lines can easily see what the trend is ...

Smart. This should be done!
This would only be the case if the commenters had NO knowledge of the other comments.The interesting, 'real' data in the comments so far is that the people who clearly heard differences, without too much difficulty, are using the same language to describe the apparent, subjective impressions.

Also "without too much difficulty" is still to be tested.
Once we know who the true golden pinnae are, then I'm definitely interested in any commonality in comments from these and ONLY these. If these august personages change their comments significantly, in da 2nd test, then they drop out of my interest list too.
Stuart'sI can think of one way, off the top of my head. Time reverse one of the files.
is a device so no tricks with files. I also take him to mean the differences should be obvious to ALL .. even deaf Golden Pinnae.I'd have no problem putting together a pair of files from DUTs that show identical distortion, level, and frequency response, but are 100% audibly different.
One possible method we've already demonstrated ... but not to 100%. Reverse the channels.
Another is to change absolute phase. Only some of my true golden pinnae can pick this up and only on certain music.
Not sure if Stuart would consider both of these cheating 🙂
BTW, a reverb has a really rotten frequency response.
