When reading this please note, this is not to spark an outcry, it is merely to ask if I need to fix something in my system.
So I was minding my own business as much as anyone can on the internet looking at linear power supplies when I clicked on this article. So if you read down a little bit in the link you run into some downloads of .wav files that you can play on your system to see if you have “nonlinearity causing audible intermodulation of the ultrasonics”. Whatever that means.
After a bit of trepidation about downloading from some random site on the internet, I finally did. I played them all, and the one that stood out for me was the 192kHz. I got a lot of noise playing that in my normal setup. So just to make sure I tried a few different ways, Roon to DirectStream, mcontrol to DirectStream, mcontrol to integrated, and finally usb stick straight into integrated, and still the noise like static.
My question is whether the file is really pushing the extremes of high frequency and not something realistic so not to worry, or do I need to try isolating different parts of my system to see if I can find the source of this “intermodulation”.
I like the sound of my system, I enjoy high res audio, and really like dsd. I never hear this static when playing normal files. But I do want to figure out the noise thing and if I should try to fix it.
