What tip/ring amp/dap combo are you using now? Just curious..
I just got mine yesterday.. haven't found the best for me yet. So far, I hate the comfort, love the sound minus some of the SSSSSSSSSSSSSSSSSSSSSS on some tracks.
Might possibly end my short journey here if I can get the right pairing for me ears.
I'm using red spacers, and clear oval tips which come with DN -1000, (not sure if DN -2000 has them) they can be seen a page or two back, Colorfly C3.
About the sibilance, while I can hear it the frequency it's peaking doesn't really dig in and 'stab me', it kind of rolls off a touch before effecting me. I've heard IEM that suffered so badly they would almost leave an after thought which made the next tiny bit of sibilance seem more emphasised, Vsonic GR01 was terrible, I couldn't handle that. so I'll let the Dunu slip.
All you can do is try different tips , insertion depths and sources, most importantly try not to let it annoy you.
