The last time that I designed something with a 4558 was an adjustable voltage regulator
for a 1974 Saab 99, back in 1980. I doubt that a more modern op-amp would have worked
better.

I started this thread because i have bunch of unused RC4558 purchased from RS COMP many yrs ago & i wanted to know if i can take advantage of them in non critical audio use.I do not recommend 4558. Although waste is a bad behavior.
And the operational amplifier does not have much difference in practical application
But I still recommend using 4580 instead of 4558.
Maybe we will waste a little money. But it will save a lot of time.
For my diy builds i always use opamp like TL0XX series, NE5532, LF353 etc. But i would love to try exotic opamp like AD & OPA series in near future.
You can use it in any audio circuit.I started this thread because i have bunch of unused RC4558 purchased from RS COMP many yrs ago & i wanted to know if i can take advantage of them in non critical audio use.

The same environment as ne5532.
In fact, I won't hear any obvious difference. I do not recommend using expensive operational amplifiers.
It doesn't make any sense.
But subjectively a lot of people has a soft corner for opamp like opa2134, which is inferior compared to cheap 5532 in spec.
5532 good. 2134 is also good. 2604 bad.But subjectively a lot of people has a soft corner for opamp like opa2134, which is inferior compared to cheap 5532 in spec.
4558 is not good either.
But they can all be used. Perhaps most people don't recognize the difference.
4558 is fine for low gain medium drive (2000 ohm) circuits. Graphic equalizers are full of them. Two years ago I built a pipe organ shade driver (volume doors) motor drive with 10 of them.
At 50x gain, they were the source of the hiss in my RA-88a disco mixer. Wrong part for that much gain, the RIAA input. 33078 sounded much better but required power rail decoupling (scandalous) and 33 pf around feedback resistor to stop oscillation.
I've never needed an OPA or Burr Brown anything for my needs. 4580 is a workhorse and about as cheap as 4558 if buying new. 5532 is cheap and quiet but a power hog.
