What difference would you expect a different IC to make over the 4558's?

Just to put this into perspective, the 4558 is little better than the rightly

I was redoing some cheap DJ stuff. One time I put in some National
chips, one of the newer designs at the time, and I found one chip
with popcorn noise. First time I ever heard that.
