Oratory wants 5dB more treble above 5kHz (which is strange as they are a tiny bit too trebly would use Amir's EQ) and Jaakko wants 4 dB less above 5kHz and rolls off -14dB at 20kHz !
Oratory seems to want 4dB more subbass than Amir yet Amir has a similar amount as Jaakko.
I guess one would have to try all 3 EQ's and see what they like. Young folks will likely prefer Jaakko's EQ.
I'll weigh in and show you my measurements. Those that would want to try some EQ should try to EQ my plot to a flat line on the plot. Do not EQ individual peaks just average levels. When I would apply smoothing (which the hearing does) then the sharp peaks and dips would not peak as high.
Below the
utopia with '1/3 oct smoothing' (purple one is Elear)
I would agree with Amir about SQ compared to HD800S.
Below my comparison between an
EQ'ed HD800 vs
Utopia and thought it would be a hard choice in SQ.
In the end... the HD800S is half the price and needs some help while I liked the Utopia without any EQ.
The Utopia had a slight metalic 'ringing' with some instruments which the HD800 didn't have but wasn't distracting nor SQ degrading.
Here's the CSD which shows some ringing and maybe shows the metalic 'sheen'
Ringing was also visible in the step which shows good tonality, excellent impulse response and the slight brightness (small bump till 0.3ms)
If I were to EQ on it perhaps very slightly lift subbass (+3dB around 30Hz), lift 2kHz a bit and lower the treble from 5kHz to 12kHz by about 2dB.
to get more data points here's Crinacle:
You can increase the bass a little when driving the headphone from a 10 ohm output R amp.
Excellent headphone.. a bit pricey and can easily get similar quality from the cheaper and lighter HD800S.
