I have both. The main difference is the corrected treble response on the CRA+ which no longer sounds grainy, harsh and overly accentuated on treble heavy music and songs with vocal sibilance present. As for the bass, i'm using short and wide bore Moondrop Spring tips on mine, and the bass response is generally similar aside from the fact that on some tracks the CRA+ has a touch more warmth and midbass presence. I don't think the bass ruins anything on both CRA and CRA+, but then again i find iems like ety extremely limp in terms of bass response so i can see people thinking that these are too bassy.
