Hi Philippe, no we didn’t, the RA C-Cu has a customized MMCX connector and not the regular one with some very small soldering points for wiring meaning only thin wires like a PW Audio 1960s will work. Tried that route before.

Never really thought of cables as needing any sort of burn-in time but if your IEM has a number of hours behind it you should be good to go.

Thanks for the heads-up on Toxic Audio cables.

Sadly no though I heard reports it’s a good pairing. I would not be surprised since the Centurion tends to accentuate detail quite well.

Oh interesting choice. Katana top-end is always a studied choice in matching for me, it is a fine balance between clean and edgy. I think if you really dig the top-end on the Katana you will enjoy the Centurion. Certainly, the air and extension on the low end are going to get a huge lift.
