Good comment.
Now I can’t prove this. But I have a theory about 2).... offsetting components is not quite as effective as 1).
First, I completely agree that 2) can be done, and should be. I have heard it... you know Benchmark DAC with PS Audio preamp ... cold detailed / warmer and more forgiving. Like that. However my feeling is this can be a sub-optimal solution compared to 1).
So, let’s just consider a trebly detailed front end and a warm next component and a trebly next component... etc. It seems each is subtractive and at the end you have a well balanced less.
So, finding the perfect house sound to your liking is best and using all the same components. I found as I slowly assembled my system, which is now all ARC that each piece seemed to be more synergistic. I think because they were all reinforcive. The same sound qualities from one to the next. Of course all companies do not have exactly the same sound across all components. But many good ones do.
As I say, I can’t prove it. I’m really not sure how you could... but working in high end audio sales you might be exposed to evidence.
