Headphoneus Supremus
I never heard any problems with the demo pair I had in home for week or the new pair I subsequently purchased, both sounded the same.
At the last meet I went to, there must have been a half dozen that I listened to from various vendors tables...all sounded the exact same (except for small changes which I attribute to upstream gear such as amps or DACs). As well, measuring headphones over 4kHz is rather difficult to reproducibly do. Might be one bad pair? It happens? Plus we don't know if this pair was mishandled, dropped, etc? This is Focal after all, this is far from their first rodeo.
Is there any date code on the Utopia ?
Yeah, I thought so. But it is nothing that should bring paranoia to any Utopia owners. They were reportedly being either Bright or just Right. Unless you hear a lot of Brightness and sibilant then it is one of those brighter one, otherwise. I know mine is not bright enough to call being uncomfortable
Yea but Bob Katz's defected pair almost perfectly matches the 3rd pair sent to Tyll. Odds that both were dropped and coincidentally damaged or defunct is unlikely.
Something has to have changed in the manufacturing, because Jude's initial measurements match w/ Tyll's initial measurements, but the two newer published measurements by Bob Katz and Tyll match.
As I noted, measuring above 8.5kHz is very difficult to do reproducibly. In fact, the variability rises to a +/- 5dB range (and up to even 18dB maximum). This is measuring the same pair of headphones too. So please take such measurements with sufficient grains of salt in this region. Hard to say what's going on with such limited data.
But Tyll's measurements of Bob's sample of the Utopias showed the entire range from 2 kHz to 10 kHz was elevated by about 5 dB, not just the area above 8.5 kHz. I don't think you can attribute that big a change to measurement variability alone.

Mine does not sound sibilant to my ears, certainly not as bright as my HD800.
As I said, very hard to say anything really with such a small sample size. It would be great if the headphone manufacturers could chime in here.
