Problems with LM4562 Opamp in Tjoeb '99 cd-player

I tried the new Lm4562 Opamp in a Tjoeb '99 cd-player as a replacement for the standard BB OPA2604. It works but not as good as it should, i guess. The sound is rather thin and hard and there is some kind of distortion in the higher frequencies even after more than 70 hours of burning in.

I think its not suited as a direct swap in this configuration, although it sounds very promissing in some ways.

Does anyone understand what goes wrong and what can be done to make it work properly?
