My six-year-old daughter flawlessly passed a blind test between a silver-plated wire and a copper one
Aspetta! Lots of ifs and buts, actually. Problems don't disappear just because you ignore them. Have you demonstrated at least to yourself that there was a sound difference when you did not 'listen with your eyes'? Have you got evidence that, beside the metal, the 2 cables did have "the same...- castleofargh

Testing audiophile claims and myths
Argghhhh. You're adding even more complexity with a somewhat different situation. If 2 people are talking at fairly similar frequencies we'll have, let's say 70dB each, so 73dB total. But if one speaks at 80dB and the other speaks at 60dB, then we get 10log(10^8+10^6)=80.04dB. The added energy...- castleofargh

Testing audiophile claims and myths
If it’s fully masked, then no. One way this happens, and even that I’m oversimplifying to a fault, is that when you hear a pure tone, there is more than just the resonating area that’s shaking in your cochlea. The area resonating just turns out to be where it’s shaking the most. So if you add...- castleofargh

And again, what does it have to do with psychoacoustic encoding? Of course the magnitude of change is important because at some point it will be perceived by a human if it passes some thresold, but in this case we need to know how loud it is relatively to what was estimated to be its masker...- castleofargh

My six-year-old daughter flawlessly passed a blind test between a silver-plated wire and a copper one
My educated guess is yes. But if we're being science serious, I just don't have the data to know when something or a sum of things becomes audible. How often have you seen a conclusive listening test done for that? It's a problem when trying to draw a conclusion about hearing impact to not have...- castleofargh

If changing the FR is the objective of a consumer, then an EQ probably is a better choice than a different cable.- castleofargh

...transducer for both cables at various frequencies(the easiest estimation would be to use the formulas for voltage divider stuff, Vout= R2/(R1+R2)*Vin where the cable's resistance at a given frequency would be added to that of the amp) and then calculate the actual FR change between the 2...- castleofargh

OP’s headphone seems to have an impedance bump centered at 70Hz so the higher impedance cable will ”increase” that area(lower everything else more). But yes, silver sounding clearer was never a rule.- castleofargh

@Vamp898 Showing that there is a difference in data in a format that exists specifically to remove data and is called lossy, is one of those ”thank you captain obvious” moments.

Testing audiophile claims and myths
The super generic answer with tunnel vision: A DAC will increase the sampling by filling in samples of the last value, or more likely with zeroes, and count on a filter to remove the extra frequencies born out of that. A computer allows you to calculate a specific value for each new sample. It...- castleofargh

Is this normal behaviour for dacs?
It's been years since I really looked into the basic settings of REW(if it works, don't touch it), but I do remember something about a default -3dB somewhere(that could be removed). I'm not sure if it was just a visual thing(shown value) or if it was real to limit the risk of clipping, but maybe...- castleofargh

Come on now. @Brahmsian clearly said he cared about objective fidelity regardless of audible improvement. There is nothing wrong with that. Discuss what you want, and let him do the same.

You start with DSD VS PCM but end with 256 DSD VS 16/44. :wink: You can find some tentative estimate for PCM equivalence in DSD, but that's all it is and even then, it's only about the resolution output for what's on the file and there is the question of the usually remaining important noise in...- castleofargh

A study that gives me pause. First because it's the first time I hear about relevant ultrasonic content in baby vocalizations, and a quick google search only seems to lead me to that one article.
