Man finding an upgrade to the HD600s is difficult honestly prefer their sonic signature over anything else in their price range, but i think upgrading to planars later down the line has reached the point of diminishing returns. I don't think i can ever part ways with them even if i do buy something more expensive ill always go back to them. That's how good I feel they are.
My HD600s certainly aren't going anywhere. I just bought an HE-560 and yes they are the better headphone and might end up as my main for at least the short term. But the HD600s not only have nostalgic value for me as my first actual foray into the Hi-Fi world, but also will continue to be my benchmark for a headphone that just does things right. The comfort, the sound quality, the price, the HD600 just nails those and are a clear example of how to make a headphone the right way in my opinion.
That upper mid peak was the reason I sold mine.
I was very sensitive to it. It stood out like a sore thumb to me.
If it hadn't been for that one little flaw, I would have kept mine without hesitation.
BTW, I also sold my Hifiman HE-560 due to a peak in the same area too. Lol.
I'm kinda glad I'm not sensitive to it; actually works well for me. And I just bought an HE-560 and am enjoying it immensely as I type this.
I compared the HE560 and the HD600 not too long ago and I found the Hifiman's lower treble to be much more bothersome relatively
The original HD6xx's had that veil. My friend has one of those and it has that sound. Senn made a silent revision somewhere down the line and neither headphone is no longer what I would consider veiled. For those looking for treble irregularities or rolled-off bass to increase "detail" it might sound veiled.
I don't have any problems with either the HD600 or the HE-560, the latter of which I actually just got today. I'm wondering if the veil thing for the HD6xx cans changed at different times. I have an HD600 that still has the old box packaging, but is new enough to have the white drivers and my bro has the HD650 with the old box as well, maybe from about 2008ish I think. When I listen to his HD650, I feel something is a little off, but all is well when listening to my HD600.
