This is the place to discuss all things to do with the HiFiMAN Arya Organic.
Here are HiFiMAN Arya Organic measurements.
B&K Default (this is going to be the the new normal for representing data, which is compensated to flat DF and represented as a tilt, because nobody likes flat DF):
B&K 5128 Raw (vs DF + 10dB Slope):
Compensated to DF + 10dB Slope:
GRAS (vs Harman OE 2018):
Note that we’re still in the process of acquiring the high res DF HRTF for the KB5000, the existing one is for the large format ear, so I’m showing this relative to Harman instead at the moment.
Sound Signature (smoothed to same degree as target):
Overall this is one of the best results for any HiFiMAN headphone I’ve come across… except for the treble, which is a bit bright sounding.
Note the 8khz constructive interference feature on the B&K 5128 (the peak there) isn’t something that we should expect to be perceptually relevant. It’s very likely this is similar to the 9khz dip on the GRAS systems which should also be ignored. So while it may look peaky, it’s really just that the whole range is boosted.
It’s also kind of remarkable that they were able to give it a bass shelf to a certain degree - and it’s… somewhat unclear just how they did this, since the two primary methods don’t seem to be at work (generally linear impedance, and there doesn’t seem to be an integrated air gap to incur the Fs).
Instead, this may in fact be a driver mode, similar to how some other models have some ‘wibbles’ in the midrange. Seemingly with this one it’s much lower down, causing a bass shelf effect. At least, that’s what this appears to be. I won’t know for sure without taking it apart, which I’m not inclined to do at the moment.
