yeah I am missing L size since I bought second hand pair and my ears are pretty Dumbo like.
so normally Azla Sedna is my pick. Trying now Divinius velvet wide bore. pretty solid.
that cable was actually the one I was going to pick thanks.
but so far this IEM might make me stop going for more single DD or even IEMs for now.
The CE600 can definitely make you stop looking for other 1DDs. Overall, very good even these days.
For the cable - choose 4.4, because the IE600 needs more amplification.
I use this cable. Awesome, it is!
