My take is that if you can hear a difference, there must be some difference.
In my case, yes, but in your case I have no idea, you could be fooling yourself. 😂
If a device or cable or whatever measures exactly the same it should sound exactly the same.
The problem I have with this argument is that it believes our existing, common measurements are all that could tell us anything about sound. I do not believe this to be true, at all. Most of the measurements audiophiles are familiar with were developed 30 years ago or more. Yes, we can measure them with more precision, but their definitions haven’t changed.
These measurements were made before high speed data collection was available and data retention and processing was a lot more expensive than it is today but unfortunately we have not really taken much of this into account in developing new measurements.
Let me give you a super simple example. Vibration control. AFAIK no one has a standardized measurement of the effects of sound on electronics but measurements and tests could be trivial.
Another kind of testing might be to measure the output at the speaker terminals with different speaker cable and compare the spectral and phase characteristics of the signal. Instead we have people spouting nonsense about theories of wave propagation through insulators that have absolutely no measurements behind them. Hell you should record it and put it in a youtube.
Before anyone asks me, I am not your lackey. I don’t get paid to do this kind of work, that’s for the magazines and gear makers to do. I’m just saying that overall the state of testing has stagnated 30 years ago and it’s a real shame.
