Actually in practice in audio, unlike cars perhaps, you may see the reverse. The effects of tweaking a system is often the opposite of the “law of diminishing returns” and 1+1 often = 2.5
Think for example about “lowering the noise floor”. Let’s say you make a change to the system that does just that. As a result you can now hear the impact of other subsequent changes that previously would have been masked in the noise now removed ... hence the increasing returns from fine tuning a system. This effect is especially prevalent in two areas: A/C power treatment and vibration management,
It often doesn’t matter in what order you make a series of changes but in any sufficiently resolving (btw not necessarily at all expensive) system the incremental and cumulative effects of further optimization should be very evident,
