There's obviously a balance to be struck between measurements and what you hear. I'm not someone who would tell anyone to sell a pair of speakers that sound great to them, but I'm also not one to scoff at measurements so easily. The measurements, math, and physics are more important than you obviously realize, but when it comes time to spend your own money, what you hear is clearly the bottom line.
I'll say this, no matter how a speaker measures you find a pair you like, then look at the measurements. The measurements will point you in a direction for the next pair you buy. If the pair you buy has a hump here, or a dip there, or "midrange mushroom cloud" as one member is fond of saying, and you love that pair of speakers, then the next time you're out buying you should look for a pair that has that. You've identified something in a speaker that you like.
It is beyond argument to say that it is a flaw in the speaker, because based on the math and physics it is a flaw, but it is a flaw that you probably enjoy. The better a speaker measures, the more accurate it will be to the source material. Now I'm not one who claims that every speaker that measures exactly the same, be it perfect or not, will sound alike, but they will sound much more similar than different based on the similarity of their respective measurements.
I'm not saying anything about the Zu speakers or the Tektons, this is all in generalities, although we will have some hard evidence about the Tektons in the somewhat near future. However, I will say that if you completely don't believe in measurements, then why are you here? This place has proved overwhelmingly in favor of measurements and accuracy. I'm not saying there's not a place for those who do not, but it just seems odd to me that two people who seem to scoff at the measurements would gravitate to a forum that holds the technical aspects in such a high regard.
To each their own.
My own personal preference is accuracy. I want a piano to sound like a piano, a cello a cello, etc. A flat response gets me close to that. If I liked a certain speaker, I'd want to see it measured to know what I like and what to look for in the future.
