We had a meeting with Charles Sprinkle who indicated it was a primary goal for the tuning to be Harman-like. We had our suspicions before the meeting too, since their marketing material also very clearly showed the "Studio" preset targeting a smooth, Harman-like response.

Yeah, one of the cooler papers in recent memory, thankful to Axel for turning me onto it. Been meaning to try the "tube" from this paper. Would love to see you give it a shot!

Arya Unveiled is $1450, but they just released the Ananda Unveiled which is going to be the cheapest in their lineup with this "extremely open" approach to acoustic design ($550), so it may be worth waiting to see if that exhibits the same behavior & if so get that one instead. I'll keep you posted!

listener @listener800.bsky.social · 18d

Very interesting, can say it looks quite a bit different than our results for the unveiled versions. Attached is data for the Arya Unveiled. The HE1000 and Susvara Unveiled both show similarly small difference in the part of the headphone response dominated by pressure effects <3 kHz (~1dB max).

Ahhh I see, thanks for sharing, this makes it very clear how it was done.

listener @listener800.bsky.social · 18d

Got it!

listener @listener800.bsky.social · 18d

It’s possible I’d opt for one of the Unveiled Hifiman headphones (AryaUV/HE1000UV/SusvaraUV) considering they’ve exhibited the least variation between Type 3.3 and 4.3 systems in our limited testing, but it’d have to be a unit that didn’t have the commonly-occuring THD issues around @ 4kHz/QC issues

listener @listener800.bsky.social · 18d

Its tough, because for all of its benefits the HD 800 still has reasonably high variation depending on how its worn, and most electrostats aren’t exceedingly well designed such that many have unintentional leaks in the front volume that change with clamp force (subject head width). 1/2

listener @listener800.bsky.social · 18d

Interesting. Was the metric tested “similarity,” or “similarity of preference”? I could see the former being a little harder/noisier to test than the latter.

Was the replicator headphone for this sufficiently placement/ear load invariant? Very excited for this but I confess I'm really hoping you didn't only use Dan's headphones for the replicator duties 😅

listener @listener800.bsky.social · Aug 23

Just gave it a pass. Very interesting indeed. Wish I was going to the conference so I could be there for the discussion.

Love my SSL 2+ except that the Phones A output has nasty channel imbalance. Love that there’s no BS software to deal with though.

See ya there, big dawg!

Any chance the HATS was a KEMAR with the Welti pinna? Your blocked canal measurements of headphones on humans + measurement fixtures showed good parity between it and humans iirc.

On that note, is there any chance you’ve done anything like a DF / SRF measurement of a KEMAR with the Welti pinna?

listener @listener800.bsky.social · Dec 19

@resolvereviews.bsky.social has a video coming on them this week!

listener @listener800.bsky.social · Dec 19

The latter I think would only work with a small sample size if you had access to a few of the same subjects from eg. the 2013 or 2015 papers though, so might be more pragmatic to do the other one :) 3/3

listener @listener800.bsky.social · Dec 19

But if it was up to me, I’d be asking you to do listening tests for OE headphones based on similar human measurements (DF HRTFs + HpTFs at the blocked canal) but testing how the LS/HS adjustments would deviate from 2013/2015 when individual HRTF is compensated for 2/?

listener @listener800.bsky.social · Dec 19

For CanJam audience I’d do “Does personalized EQ based on listener HRTF correlate to reports of ‘technicalities’?”

Can measure DF HRTFs + HpTFs for a few people at the blocked ear&do listening tests with an HD 800S and see which profile—stock or personalized—has more reported soundstage/detail 1/?

listener @listener800.bsky.social · Dec 16

Ah okay that makes a lot more sense. Waaaay easier to avoid dealing with anything past the canal entrance 😂

& no kidding! Hats off to that engineer of yours.

listener @listener800.bsky.social · Dec 16

Looks like very clean work. Done in 00 35 silicone, I assume?

I also assume you’re terminating this in a 711 coupler (or perhaps the ear sim from the HMS type 4.4 system), where did you decide to terminate the canal/place the microphone?

listener @listener800.bsky.social · Dec 16

are those custom pinnae?
