I have a Onkyo M-5030 Power Amp and an Onkyo A-809 Integrated Amplifier that I would like to see about possibly getting more detail sound wise.
If I understand things correctly the OPA-2134 has a Higher Input Impedance and output than the NJM4558D hope I'm saying this right.
I don't know where to start to figure out how or what to change component wise on my Circuit Board to accommodate the OPA-2134 if this possible.
Also, the Output Transistors are 2SA1106 & 2SC2581 which are no longer available would be grateful for any advice.

What makes you think that the opamp in M-5030 has anything to do with sound quality?
Audio op amps in the Onkyo M-5030 are only for the offset integrator, which should have minimal effect on the sound.
The Onkyo A-809 phono preamp does have an audio op amp Q105, plus another one for the phono offset integrator.
However, there can be unknown consequences from simply changing parts in the design.

I would like to thank everyone for replying to my question about me inquiring about a possible change out of the NJM4558D I'm very humbled,
by the fact I need to learn much more concerning circuit analysis my end goal was to try and reduce noise and improve frequency response.
Thank again everyone!!!!!!!!
