Low price is usually a function of volume sold, so its not uncommon that a cheap device is a good performer, especially if its been around for a while, so long as you pick the right cheap device

"Good' and "low cost" can go together well, "excellent" and "low cost" less so.

If your unit is the original one, the service manual doesn't give a components list to match the schematic. So it's hard to say what opamp to change...

At least 3 4558 are there to drive leds, not a very critical task.

That's a very good task for a 4558. I certainly would not want to have one in the audio path.
