Yes, it works. A good example is the Brainwavz B100 vs. the Brainwavz B200 v1. Both even look identical and cannot be optically distinguished. The B100 sports a single, hard working driver and the B200 has a couple of lazier ones that share the work.This is the part I am never able to understand. How can it be the same signature and yet different enough to have more details and sound stage. Would that not be a change to the signature? I think I would be unable to answer a question like that, no matter how many iems I have.
Both have the same basic flavour based on a fast attacking and fast decaying (=dry) bass. But the B200 resolves better, has a rounder low end and more sheen in the midrange. When you look at the graphs - I know you prefer not pushing the spoiler button - you'll see the similarities. In fact, they are almost identical. The kicker is that most would guess the bigger spike in the upper midrange belonged to the livelier sounding B200 - but it belongs to the B100.
This tells us that the FR graphs don't give any qualitative information (soundstage, detail etc.) and that two earphones with very similar frequency responses can grossly differ in their sound qualities.
