opus#1 and sr25 have diff dac. you mean the opus#1s, the same cs43198. opus#1 has cs4398

@borjok536 yeah, just a typo

I'm seriously thinking about getting this. It's between this and N6 E02...

Thanks for this helpful write-up.

I had the SR15 and didn’t like the sound signature. Too warm for my taste and for most of my IEMs. Especially female vocals were pushed back and without engagement. Its a laid-back sound, suitable for falling asleep, but I need source for a commuting.
