    I used Roon ROCK OS, which is based on Linux if that counts. If the Linux version you want to use supports UAC2 it will likely work. Windows older than 10, no.

    I tested the beta with Solus Linux (desktop-focused) and both Rhythmbox and DeadBeef. Had issues with Rhythmbox, but DeadBeef using the ALSA backend worked perfectly. I suspect other distros with software using ALSA should work fine with the release firmware.

    At the time of the beta, OpenBSD didn't support USB2 audio, but it does now. Haven't had time to go back and try it again yet, but I'll get there. Also have a FreeNAS here (FreeBSD), which I've not yet tested, but will soon.

    I'm confused by this post - perhaps I haven't been following along well.

    How is it that you are able to get a Unison USB upgrade on your Yggdrasil? Are you part of a beta program? I thought that @schiit has said that Unison won't be available until the demise of Win/7. Perhaps he's referring to a different form factor release?

    One reason I ask as I've been holding off sending my Yggdrasil back to the mothership for an A1=>A2 upgrade, wanting to do both Unison and A2 upgrades on one cycle.

    It was a closed beta.

    Just wait until next year. Keep in mind that A2 does sound different from A1, so if you've built a synergistic or optimized system around the A1, you may have to resort to tweaks to get the system back to how it sounded like.

    There's an ominous fog about... the Gungnir I feel, as we know it, is not long for this world by any stretch of the imagination. Many many clues.

    I find this message a little foggy. :)

    Yggdrasil and Gungnir Multibit are getting old.
    Maybe we get more than just Unison in the new year...

    To those who had a Unison board in their Bifrost Multibit, did the music become more engaging?

    In my speaker setup, the BM is resolving, has great separation of layers, no hint of music being muddled...but it just doesn't engage me like the Modi 3 does. On technicalities (clarity, separation, focus, blackground, etc.) the BM is clearly superior to the Modi 3 but I'm still left with dissatisfaction. The Modi 3 has a bit of bloom that I find pleasing to my ear, even if details are a bit smeared. (On another note, the lack of microdynamics from the Vidar has become obvious after switching DACs)

    I read impressions of the Unison that there is a kind of tube-like bloom and less of a "reference" sound. This might make the BM a preferable DAC in my speaker setup. Just curious how dramatic the change in sound will be.

    I've used EITR, built-in USB, and CD transport SPDIF coax with my Bifrost.

    On the other hand, I prefer the BM with the HE-6, it just plays to its strengths better.

    I think the Unison in my Bifrost Multibit removed some haze and brought in clarity. Less grey backgrounds, more plankton, and engaging, but not in a lush tube-like kind of way. It just sounded more accurate, but it might highlight the leanness of the first gen. Bifrost Multibit.

    Yes. More blackground, more clarity, more engaging.

    Yggdrasil Old? The analogue 2 upgrade for Yggdrasil is hardly 2 years old.
    I'm anxiously awaiting the Unison USB module to upgrade.

    I don't think DAC needs yearly upgrade. I feel both these DACs are fantastic and in Jan we will get USB upgrade anyways. Plus Schiit has launched Bifrost 2

    Will the Unison upgrade have a self-service option?

    If Gungnir, I believe you have to send it in for a firmware update on the motherboard.

    Don't take this as gospel since I am writing from memory of the thread at HF but if you swear you are competent to install it I believe Schiit will sell you the Unison USB board for older Bifrost and Yggdrasil only to install yourself when available next year. Look at some of the videos on Schiit's YouTube channel.

    Thanks. Yeah, this will be going into an older Yggdrasil.

    @purr1n - thanks for the detailed instructions for the previous Yggdrasil upgrade. Just wondering if the Yggdrasil screws were easy to strip or pretty durable for being non-steel screws?

    My biggest concern would be if the Yggdrasil Unison board were overly complex or larger, resulting in a difficult at-home install. The process would seem to be much easier if it were a simple rPi hat-like board.

    But I’ve got this friend named Murphy, and he’s got this Law...

    That dude is never wrong.
