I may be guessing here, but in my case, i suspect the 5532 puts a "heavier load" on the input connections compared to 4558. If there are resistors in seriesNoob question…
Some are reporting changes in the sound volume when rolling opamps. I was under the impression that the external components—what is not “rolled”—were defining the operating conditions/range of the opamp. Hence the no audible difference if these components are the same.
A change in volume is reasonably easy to hear. But is it also an indication that’s there could be other differences (some being audible) due to the way the opamp is used in the circuit?
of the OP-amp inputs (outside of feedback loop) it can have an influence. But that is just a guess.
