This was originally posted on ASR just now, but I really want the sound science users take on it. Particularly @gregorio , @castleofargh and @bigshot .
Hello everyone. First, a bit of preamble that hopefully will make sense once I come around to the point I'm trying to make at the end.
I am a former subjectivist - read my story here: https://www.audiosciencereview.com/forum/index.php?threads/repentant-subjectivist.22411/
I have recently come back to the hobby after years of absence "just" owning a "poverty entry level" rig of Stax L500 mk2 > 006t > modi 3. Because of better listening conditions in our new home, I am returning and got the 007mk2/L700mk2 > 727II > Eversolo Z8 DAC going. This newfound interest has of course once again subjected me to the classic audiophile discourse. But it has also subjected me to my own bias' and how I interpret the different equipment. I am doing my best to remain rational in a field where I understand very little.
When I changed the 006t amplifier to the 727II amplifier on the L700, I didn't expect to hear any changes. However, I certaintly did. The subjectivist in me wants to say that the sound became a bit brighter, a bit more detailed and a bit more engaging. For better or worse, as the L700 through the 006t was a serene and relaxing listening experience that, although less "resolving" sounded fantastic. Now I'm sure this effect is most likely due to either higher listening volumes or just expectation bias etc.
I EQ all my headphones through roon after oratory1990 settings to Harman target. It is obvious to me that while the headphones post EQ might measure very similar, they don't actually sound similar. I am very confident that I would be able to discern between different headphones EQ'ed to the same curve in a double blind test. If only there was a way to not tell by the sensation of the headphones on my head. Either way, this tells me that surely there must be other measurements than just distortion figures and frequency response that explains the sound difference. Size and shape of the driver, earpad thickness etc surely plays a role.
One of the main reasons for me evening "seeing the light" and understanding that the audiophile hobby is mostly a combination of psychoacoustics and dopamine addiction is the topic of electrostatic amplifiers. When I bought a pair of Stax SR-007mk1 and paired it with a 727II, I kept reading about how this was a bad sounding combination and that I needed a $ 6000 USD third party amplifier to drive the headphones. This to me seemed so ridiculous that I started questioning it, and it led me down the path I am still on to this day. My thinking is that if the SR-007 sounds vastly improved through the Mjolnir Carbon (6k third party amp) compared to the Stax SRM-727II amp, there should be a way to measure it. But as I understand it, the frequency response will actually be the same no matter what amp you run it through. However it is also clear that a severely underpowered electrostatic headphone will sound very bad. My personal experience putting the 007 into the entry level 252s amp sounded terrible - broken almost. I would be confident I could easily discern between the 252s and 727II. This might come down to distortion, but I don't know.
Anyways, my thought has always been that if the difference is as big as the "stax mafia" proclaims - why would they not produce measurements or tests that actually prove this difference? Many of these people own a ridiculous amount of gear, have the necessary knowledge to pull of measurement/tests and would clearly have an interest - sometimes even commercial interest, possibly. So when they don't do that, it makes me think they just don't want to know the results. And that may very well be the case.
So, to the point of blind tests. When I was still a gung ho subjectivist, I remember having some opinions on the limits of blind tests. These opinions weren't very well developed, but there was something in me intuitively that told me that blind testing was very limited. I remember thinking something along the lines of - "well, if I can't "put the sound on a mental coat rack so to speak", then I can't properly interpret it." And I suppose this might be correct, and my opinion on blind tests in a way coming down to me not understand what "objective" even means - just acknowledging the interpretation part should've made me realize that I needed to read up on psychoacoustics.
I'm largely confused about it all, but I saw something I found interesting on TV the other day. Basically, there is a Norwegian christmas advent calendar show on the state channel that has celebrities go through various christmas related challenges. In one of the challenges, they were tasked to identify various food items from a christmas cold table with limited senses.
Task 1 was to identify the food without seeing or otherwise touching it, while being spoon fed it. They were fed "pultost", a matured sour milk cheese.
Task 2 was to identify the food by smell only. The food was pickled herring.
Task 3 was to identify food in a opaque container by shaking the container. The food was rice porridge.
Task 4 was to identify the food by touch only. The food was beetroot salad.
Task 5 was to identify the food by sight only, except it was placed a far distance from them. The food was a slab of pork ribs.
Task 6 was to use their "6th sense" by essentially guessing what hid under a lid without having any way of inspecting what was under. The food was cabaret.
Most if not all of these food items is something adult norwegians will have a close relationship with, having eaten it most every christmas for their entire lives. To my surprise, almost none of the contestants could identify the items. The most interesting test to me was the pickled herring smell test. Pickled herring is extremely popular and has a quite distinct smell which most if not all contestants would be familiar with. Yet only 1 or 2 out of about 14-15 contestants managed to correctly identify it as pickled herring.
This made me think about a claim I have often heard when it comes to blind testing: "If you can't hear a difference in a blind test, then for all intents and purposes there is no difference in actual sound to that person".
I can't remember exactly what the contestants on the show said they believed the smell from the pickled herring was, but there was a lot of different responses from things that certaintly smells nothing like pickled herring. We can assume that since they wrongly identified the pickled herring from these items, they may be unable to differentiate pickled herring from things smelling very different in a blind test. My question then is, would this mean that in terms of smell - there isn't actually a difference because we wouldn't be able to differentiate it between a blind test? Surely not, right?
I can imagine someone knowledgeable reading this and laughing their ass of, since it probably shows a big lack of understanding in basically everything I'm talking about. But my idea here is basically that identifying something from smell looked to become almost impossible when not getting to see the foods. Same with taste and feel. This tells me that our senses of taste and smell is incredibly bad - bordering on useless - without the aid of sight. If this is true to some extent in regards to hearing, wouldn't this mean that blind testing is in fact almost useless because of our reliance on other senses to interpret sound?
Basically, if our senses of hearing is so lost if we isolate it - how useful is it to ascertain that we can't differentiate between gear in a blind test? All it would tell us is essentially that humans sense of hearing sucks. It doesn't seem to say a whole lot about whether or not there actually is a difference in sound, but rather that we can't discern a difference in a blind test. But in the same way I would hesitatet to say that the difference in smell between lets say pickled herring and beetroot salad is just bias and voodoo because a person couldn't smell the difference in a blind test - and thus no difference in smell actually exists - , I wouldn't say that a lack of discernment between equipment in blind test means that there isn't any difference in sound.
Of course where something measures the same, it must also sound the same objectively. But it feels like there are limitations to this, re: same frequency response but different sounds etc.
Okay I guess I'll stop typing and pray that I've made sense to some degree.
