Smile Op-Amps replacements

How is everybody doing today?

I d like to change the opamps in my cdplayer,and the stock and replacement Op-Amp numbers are:

1.)TL071 to be replaced with OPA627
2.)LM741 to be replaced with OPA604
3.)NE5532 to be replaced with OPA2134

Are the replacements Op-Amps the right ones for the stocks?

Just check the supply voltage on the NE5532, it can take higher voltages than your replacement. Apart from that the choices seem fine although it is difficult to say without a schematic. What does the LM741 do in the cdplayer ?

Thanks for the reply.
I do not have the schematics,but do you think the replacements should be alright?
The LM741 is acting as a servo or something,i m not too sure,but thats what i think it is.
