I'd have to say, you're pretty sensitive to the highs there, all right. Don't think anyone has found the HE-1000 bright or sibilant (not so for the HE-560, which I did find that way initially, but either improved with burn in or brain burn in over time). Maybe the benefit of getting older and losing those high frequencies...
I agree... He is overly sensitive.
BobFiggins, you should actually have your hearing tested officially. If you can hear 20k or even higher...well... you're a mutant j/k
But the HE1000 was far from sibilant. I would love to have heard the Zoetic with the HE1000 as I know that particular cable has the best synergy with the HE1000's of all cables. I tried it with the Norne Solv and had no sense of sibilance whatsoever.
I'm most interested to find out your actual sensitivity to frequency tests.
test it, please... link above.
I can only hear up to 16,500hz, and the range is generally 20hz-20khz...but from what I understand there is a small amount of humans over 24 years old can hear frequencies above 16Khz.
