Yes, most do, but not all of them. While I don't outright dislike my Bifrost 2, it is by far my least favorite of all the Schiit DACs I've "tasted".
Please note that I have never listened to a Modi (Multibit or otherwise), but I own(ed) a Hel 1, a Hel 2e, a Modius, a Bifrost 2, a Gungnir Multibit, and an Yggy OG. And out of all of those, Bifrost 2 is the least euphonic to my ear. It's much too warm-sounding for my taste, and it very much lacks when it comes to imaging and staging. I'd say that it is probably the least resolving of all the Schiit DACs I'm familiar with.
Depending on your rig, however, this could end up being a feature, not a bug. Here's what I mean:
I am more or less exclusively listening through tubes, not solid-state (pre-)amps. Tubes tend to be on the warmer end of the spectrum to begin with, and layering Bifrost 2's warm sound signature on top of that might just be "too much of a good thing" for me.
So if you enjoy a somewhat tube-y sound yourself and you're predominantly using solid-state (pre-)amps, however, I think you've got a pretty good chance of actually enjoying what you get out of a Bifrost.
Personally, I'm a total sucker for detail retrieval, so I prefer the output that Modius, Gumby and Yggy deliver over Bifrost's. The huge downside to this is that sub-par recordings and compressed stuff can sound much better on something that's less revealing and thus more forgiving; like Bifrost.
My best guess would be that you will not enjoy Bifrost 2 if most of the following applies to you:
- you use a tube (pre-)amp
- you prefer revealing headphones like planars or ribbons
- you like your sound "clean", by which I mean detailed and revealing
- you want a maximum of staging and imaging
- you have access to lossless and/or exceptionally mastered sources
- you predominantly listen to classical music (where detail and imaging is crucial)
…and that you will enjoy Bifrost 2 if most of the following applies to you:
- you use a solid-state (pre-)amp
- you prefer the sound you get from dynamic headphones
- you enjoy revealing headphones like planars or ribbons, but sometimes find them a bit too harsh
- you feel that "loud" is more important to you than "accuracy"
- you like a "tube-adjacent" or "analog-adjacent" sound signature
- you want to listen to compressed sources and need a way to somewhat "hide" the harsh highs and other compression artifacts
- you predominantly listen to acoustic, indy, rock, or pop music
- you absolutely MUST have a remote control ;p
