By the way when I say your wife, dog or neighbors won't let you use speakers, I'm talking about me. Except in my case it is my wife, my neighbors and their dog that don't like my speakers or my music.
Look, if you are using graphs to make purchasing decisions you are going about this in the wrong way in my opinion. My dealer lets me borrow the phones for two weeks before making a decision. There is no need for graphs when I can use my ears to compare.
I understand what people say about the Grado treble, ect, because I've heard it myself. But in my opinion, that harshness or sibilance is nothing but noise in your system that the Grado is just relaying. It could be anything, issues with your power lines, deficiencies in the way your dac or amp is designed. One issue Ayre addressed with the DSD upgrade to their QB-9 DAC was the power supply to the USB interface, for example, which supposedly makes performance more consistent regardless of what computer, motherboard, or usb port you are using. When I made that upgrade, some recordings that used to be a bit harsh now tickle your ears with the PS1000. When you make improvements to upstream components like that and the headphones sound TOTALLY different, that is transparency. When the headphones put their ugly sound signature on everything you listen to, that is a problem. I don't hear a Grado sound at all. They TOTALLY disappear. I think they have a really bad rap on these forums.
I'm sorry, but this is circular logic. You are presenting a theory that can't be falsified. If anybody experiences something different it can never be the headphone, it has to be everything else. Not trying to be rude or argumentative, but if this was an argument being presented as a valid theory (which in reality it is) it fails the very first test of a good theory; that being that if a theory can't be falsified, it is not a good theory. There are several other possible explanations that you are seemingly discounting out of hand. One such alternative explanation is that you are less sensitive to the particular sound signature that for others is an issue. That seems far more plausible then micro levels of noise being delivered through utility power having such a profound effect on the sound.
