FWIW, I didn't anticipate that a simple question about an impedance curve would snowball like this.
I never asked for a frequency curve (which I know can be contentious), but I saw (and still see) little harm in asking about an impedance curve. No competitor is going to attempt to 'copy' an impedance curve.
I would have asked the same question of any CIEM maker. The only reason I happened to ask it in relation to a Noble product is simply because the sound signature of the K10 might suit me, but I would have liked to know how demanding the K10 can potentially be, to drive (UM Miracle, which I owned previously, drops notably lower than some other CIEMs, for example. Incidentally, UM seem to have no qualms at all about releasing frequency curve charts, and even include one, as standard, with every pair of CIEMs they sell).
It wasn't intended to be a contentious question; just a sincere one, and a simple 'yes' or 'no' would have sufficed, rather than a "HELL NO!!"
No matter. You've made your standpoint abundantly clear & I won't make the mistake of asking for any technical details on the K10 again.
