    Review and Measurements of New JDS Labs Atom Headphone Amp

    That is annoying. Any idea what EQ program Oratory1990 is using? Edit: Are you sure? The graphs look pretty similar to me, except that I reduced the low shelf a little to taste. https://www.dropbox.com/s/rp71fprbe1lmz7u/Hifiman%20HE4XX.pdf?dl=0

    "You wouldn't download a car..." Turns out maybe you can? The free endgame solution for objectivists

    Most of the CSD plots of headphones I've seen only go out to five milliseconds. Room acoustic measurements generally look at hundreds of milliseconds, so it's hard to see how a couple milliseconds would have much effect. Headphones usually have much lower distortion than loudspeakers as well...

    Review and Measurements of New JDS Labs Atom Headphone Amp

    It looks like the AutoEQ values actually roll off high frequencies quite a bit more than Oratory1990's PDF: Oratory1990 doesn't try to correct anything above 10kHz or so: (I subtracted about 1.5dB from bass in both examples to compensate for GoodHertz CanOpener crossfeed plugin.)

    Review and Measurements of New JDS Labs Atom Headphone Amp

    It looks like oratory1990 measurements are included in the AutoEQ output. Are you referring to the referenceaudioanalyzer category? https://github.com/jaakkopasanen/AutoEq/tree/master/results Edit: Actually, it looks like Oratory1990's settings are a bit different. There's an index here...

    Review and Measurements of New JDS Labs Atom Headphone Amp

    I think you'd be better-served EQ'ing the HE4XX to a Harman target. HE4XX has low enough distortion to handle a nice bass boost and JDS Atom has plenty of headroom to drive them, even with -7dB preamp for PEQ...

    Need help deciding between the Schiit Heresy and JDS Labs Atom

    I got the Atom because I thought the headphone plug to the left of the volume knob would be less annoying. However, if you’re left-handed or use the Atom in low gain, you will have the same annoyance.

    Headphone Correction & Spatialization

    I like your filter better than Waves, but none of these make me think I'm listening to speakers. I think I prefer CanOpener.

    Headphone Correction & Spatialization

    It's shifted forward a bit, especially at the sides, but I wouldn't say it sounds like speakers. I don't hear it with your video, either.

    Did you try CanOpener? It seems pretty transparent except for the potential issue noted by the OP.

    Headphone Correction & Spatialization

    The first picture I posted shows no obvious FR change with the left channel only driven. The second picture shows both channels driven with pink noise.

    I think it's more an effort to mitigate the unnatural soundstage of headphones.

    Wouldn't that just create a tonal imbalance for anything hard-panned to the left or right? I don't find the effect on the center image unpleasant.

    But has Amir measured the SINAD? ;)

    Headphone Correction & Spatialization

    Thanks. I had a hunch and generated pink noise with REW: With both channels driven the cancellation appears: It seems to be increased by the angle setting. These pictures show the angle at 75°. Setting the angle to 0° removes the effect, so I'd be reluctant to cancel it out with EQ.

    Headphone Correction & Spatialization

    Can you post the actual values for the filters? Usually people comment on a slight bass emphasis with this plugin, which is pretty normal for crossfeed. I’d be interested to hear some feedback from Goodhertz on this.

    Headphone Correction & Spatialization

    I had to install a new trial version since my licensed version doesn't support 64-bit VST. After activating the WDM driver and messing with buffers, I think I got a pretty good results with CanOpener. Qobuz is feeding the Jriver driver with WASAPI exclusive mode. CanOpener seems to create a...

    Possibly... I haven’t used Jriver in years, but maybe I can still get an upgrade discount. I have no idea what kind of latency or CPU usage it has.

    Yes, it basically creates a fake sound card in Windows that you can select as default audio output. All processing through Jriver, including VST, gets passed to your real audio device selected in Jriver.
