The LEDs are less bright than the
Silver LightDims covered one of the Jotunheim:
The metal work looks smoother than the Jotunheim's and Mimby's, with a slightly different tint, and the print is darker and thicker. I don't know whether that just faded over time or came like that, though.
While hooking it up, I realized that the XLR jacks are upside down. I know the cards are mounted upside down, and maybe this is the only way you can attach the jacks to the card. It threw me off when I was trying to insert XLR cables though, because I was doing it without seeing the jacks.
Jotunheim vs. Bifrost 2, crops of images from schiit.com:
With the Ragnarok 2, muting turns off the speaker and/or headphone LED instantly, and it stays off. With the Bifrost 2, muting is a bit more playful:
I'll save sound impressions for later.
Edit: Another little side note, unlike Mimby, Bifrost 2 does not have an "Enhancement" tab in the Windows control panel. I only looked for that to check "Disable all enhancements", but if you rely on the EQ features normally available there, they won't be available with Unison.
The "Spatial sound" tab, however, is still available.
