Who ONLY relies on graphs for anything? That would be dumb and NOBODY does it, not even Crinacle who measures everything. It would be as dumb to exclusively use graphs to make product purchases as it would be to completely ignore them as being useless. There is clear utility in graphs. If there weren't, nobody would be doing them. The most important way I use graphs is for EQing. Not all monitors take kindly to EQing. Some, like the Z1R, become magical when you do EQ them. Over time, you can create your own preference curve so fine tune your monitors to your own taste. Moreover, in a hobby that is so dramatically impacted by subjective impressions, it is helpful to ground yourself in something objective like a graph. None of this is a replacement for actually hearing and critically listening to a product. But even then, our own hearing deceives us and we need tools for eliminating expectation bias such as that built up by reading hundreds of posts on a thread about how great and infallible a monitor is when we know instinctively that no product is perfect. Yes, we hype things up so much that sometimes we can't be objective anymore.
I always look at the graphs to try to learn more about how what I am hearing correlates to measurements so that I can begin to better understand what is going on. I use graphs the same way I do professional reviews, user impressions and technical specs. I use them as INPUT for creating short lists of products I may want to purchase or audition. When I see something that surprises me, that's a good thing, because it is an opportunity to learn something about audio that I didn't know before. What did I learn here? That a big scoop in lower treble might not be a problem, but I am wondering what impact this will have when pairing it with a transformer tube amp. Since tube amps achieve tube sound by introducing distortion to the 2nd and 3rd harmonics, how will this be impacted? That is a question worth investigating and testing which is something I will be doing when I get my Traillii. I only decided to do this test because I saw the graph. That's why I NEVER ignore graphs.
