Planar IEMs currently need more power than your CCA CRA. So you’d need more gain/volume at the same power level to make your planar IEM sound as emotionally impactful as the CRA.

Honestly… makes the planar a bit safer for your longterm hearing prospects.

Your phone’s 3.5 jack has 24bit/192kHz audio output.

This is as good as it gets for current digital audio.

You need no other DAC to enjoy lossless audio.

KZ accessories are not good. They are ok. All of their ear tips made my ears produce more ear wax than usual. That’s an immune system response.

Your ears maybe happier trying something from another brand. There are silicone tips with foam underneath. Might be the comfort and fit you’d like.
