Well, S8 doesn't make SE846 sound bad, but S8 is just better overall. Mainly in treble and imaging (S8 seems to be very compatible with my HRTF, it's a best imaging / holographic sound I'm getting with any HP/IEM I have used in the last 20 years). I always had an issue with SE846's tips. None of the stock tips sound good to me, the best sound I'm getting with them is with some cheap triple flanges. But I can't wear them very long, it's getting too uncomfortable. Second best, which I'm actually using now, are SpinFits CP800. Very comfortable. But they don't go that deep, and so the treble peak moves to a lower frequency, around 8kHz, where it's causing some sibilance. With deeper fit of the triple flanges this peak is moved to something around 10 kHz, which sounds much better. So, with CP800 and white filters, it's sometimes too sibilant, with CP800 and blue filters (with foams removed) it's less sibilance, but also less treble overall... With an S8, I don't have any issues at all, they are shallow fit, so I don't have any comfort issues, and they just sound consistently incredible with everything.
