Well if the measuring instrument has to be 10x better than what you are measuring and you are using ears to listen to a speaker with a distortion level of -50dB then perhaps the best you could hope to hear is around -40dB distortion level???
You mean with respect to amplitude of frequency response? If so, yes, it is about 0.03 dB. But this is across 1 microvolt to whopping 160 volts and full bandwidth. For 20 to 20 kHz the accuracy improves to 0.008 dB for lower than 20 volt input. This is far, far more accurate than our hearing thresholds.0.3 dB? How far down can measuring gear measure to? Amir? 0.03 dB? I'm not a measuring guru but input would be appreciated.
Which is stated to be ~0.2dB.This is far, far more accurate than our hearing thresholds.
My preamp's volume control goes is reasonably accurate 1dB steps, and on music I generally don't notice 1dB reduction even when I know I've just done it!Which is stated to be ~0.2dB.

You can change to other levels as well. Even a -1dB change (~20% wattage reduction) is not noticeable if not immediately listening for it (if I lowered the volume of your system by 1dB and you came back the next day, you wouldn’t notice).
But that is irrelevant. Sure, we have unique and constant HRTFs (and central processes, as well) but, because they are fixed, their filter on a frequency-flat signal is the same as it is on a stage band or a string quartet. Flat has no meaning except as a reference.What's flat for me isn't necessarily for you.
Puts the 1dB cable induced differences (if they exist) into perspective...

That's not quite right IMHO. Each person's pinnae puts the input through its own specific filter, but that's the same filter that every sound that person hears goes through. So in this respect, flat is the same for everyone.*
*Headphones are a special case of course.
Irrelevant. When you hear live music, you hear it in the special way your ears let you.What's flat for me isn't necessarily for you.
Human's hearing is isolated/ independent from reproduction. When people go to concert the performance itself is the same, the human perception is irrelevant from objective reproduction. Subjective preference however can be very different.Would agree with the flat-is-flat aspect... however, considering that almost nothing is truly flat... the graph would clearly indicate where subtle peaks or dips would be more dramatic (and potentially unpleasant) to one listener than another. Without a similar graph of a subjective reviewer's hearing - there's no way to know where they're "naturally attenuated" (and without your own, no way to compare the two to have an idea if you would hear the sound similarly).
Sure is nice to have objective measurements in such cases.

You mean "mole man", the guy with all those underground rooms, etc?Is that Marty Feldman or the hoarder on American Pickers? God, the programs I watch.

I hate to admit knowing this.
