The definition of synergy is that the sum is greater than the individual parts. The sum is undefined, making synergy something of an irrelevant term in audio.
That being the case, and more relevant, is each person tries to build a system that is pleasing to them. Similarly, each piece of equipment is designed with some sonic signature that is pleasing to the designer, given nothing is perfect. Of course, interactions among components come into play, which is beyond the control of individual designers. So you have a choice, either find a designer/brand that matches your tastes, or mix and match until you come up with something you like.
Again, the sum, or perfection is undefinable, therefore different for each person. So synergy as you have defined it really has no useful meaning.
If you are talking about mixing and matching to compensate for unappealing designs, I'm curious why someone would do such a thing. Why not just pick components you actually like, following basic principles like impedance matching, efficiency etc?
