Headphoneus Supremus
With a little help from my friends @slumberman, @Tokpakorlo, and @Deezel177 I spent way too much time on EQ experiments over the past week. The reason that I did in the first place was trying to find a way to potentially make Onyx work for me the way I wanted to, and I thought experimenting with my current setup as a preparation (which includes a great parametric Lotoo equalizer) would give me a headstart.
At the end of the week I had narrowed the influence of the equalizer all the way down to barely 2 -0.5 dB steps though and still wasn't satisfied. Of course 2 tiny corrections didn't even come close to what I had in mind as these steps on paper barely do anything for amplifying/attenuating certain frequencies, but it somehow still did something I didn't like at all. Without having the technical background to explain or prove this (other than that anyone can try for himself) I guess what I'm hearing is that apart from attenuating for instance a pure 5 kHz tone of which I could clearly hear the effect of, something happened to a great many other tones that were clearly not even near that 5 kHz. What I now think happens with EQ-ing (and that probably makes sense) is that when I attenuate a 5 kHz tone, not only do I attenuate exactly that tone, but also all kinds of other tones that have all kinds of under- and overtones (harmonics) of that 5 kHz tone in them.
I found it strange that for instance recordings of small ensembles started to sound like if the air was sucked out between the instruments, and that their natural echoes that help pinpoint imaging within the soundstage stopped being there, or at least they didn't seem to be connected in a natural way any longer. From what originally sounded like a great 2 mic setup recording it turned into something in which every instrument was recorded with its own mic in a separate room and then mixed together to recreate a seemingly authentic natural recording - except that it didn't. So what I think is happening with even the slightest EQ-ing of a certain frequency, is that not only does it influence that one tone, but also all other tones that have some harmonics related to that tone in them, sucks that one part out (exaggerated, as it's just attenuating them) and breaks the natural decay (and timbre?) of any tone. Probably the natural dying out of for instance a 500 Hz tone that has just been played has a handful of harmonics from a 5 kHz tone from which perhaps the middle one gets cut out this way, leading to some kind of unnatural reverb? And when you try to EQ more than just one tone this cuts out even more harmonics of that natural reverb of many other tones and the echoes of the instruments of that natural 2 mic recording are not working together any longer to give you the natural impression of them being played in one space right there in front of you. So you clearly hear the instruments in order, but something doesn't add up any longer.
My experiments worked for finding the best handful of techniques to EQ to reach a certain effect so I'm certainly happy with that part. It's just that I'm not ready to accept the by-effects from a nerdy audiophile point of view just yet.
If anyone has a better and well educated response to what I'm actually hearing then I'm all ears!
