Any owners of Schitt Bifrost 2?

I had a Yggy LiM and loved it. Then I had a need for a DAC with a volume control so I ended up with a PS Audio DS Mk 1. It's easily better as far as detail and bass weight. Music just has more presence and "thereness" (hey, I invented a new buzzword!) with the DS. I would never disparage anyone that says the Yggy is their favorite DAC, though. It's excellent. I will say that now that I've experienced the difference an I2S connection makes the lack of one on the Yggy would give me pause. Of course, your source component(s) also need one so it may be a moot point for you.

I have a Bifrost 2 with PS Audio power cable, 

AudioQuest Cobra Interconnects,

Kimber Cable D60 digital cable 

AudioQuest Carbon USB Cable 1.5 meter

Just resent i added a Synergistics Research 

Purple Fuse, .75 inch, 300mA slow blow.

Just Recently I added a Synergistics Research

Purple Fuse .75 in 500mA Slow Blow.

You might want to check out a used Bifrost -- they come up for sale regularly. You could buy one and then resell it for about the same you paid if it doesn't float your boat or you just get the urge to move on.

I have a Bifrost 2 and a Modi Multibit.

I think the first question regarding Schiit DACs and other choices is: are you satisfied with 24/192 PCM data, or do you want DSD or MQA and can that be decoded before the Schiit DAC.

I have what many here call a LoFi system. I am in an apartment, and the room layout and space do not lend themselves to high end audio. Using an M2 Mac Mini for the stream, to a Denon AVRX3700 to Ascend Audio Sierra speakers with an SVS SB 1000 pro sub. Took a lot of play with the Denon to optimize for 2 channel and balance the speakers and sub.

The Bifrost 2 is a noticeable step up from the Modi Multibit, but not large. In the above base, the Bifrost 2 has slightly more depth and separation. Overall sound stage is about the same.

Recently, added a restored Luxman M120 for the L&R amplification and even without dialing everything in, the depth, width, and separation jumped to a whole new level. Looking to add a dedicated preamp, and stop using the Denon as a pre. Added this info to say that your environment, preamp, amp, and speakers have a lot to do with what you will hear from any DAC. Haven’t heard any version of the Yggdrasil, so can’t say if it would be better in my system. Based on specs, it is a big step up, but would that be audible in my system?

All of this is to say that audio is the sum of the parts, and anybody’s system can evolve. The Yggdrasil may be end game DAC, but is the rest of your system comparable? Agree with the other posters, try a Bifrost 2/64, or at least a used Bifrost 2 and see if it performs for you and your system. Then you can decide if pushing further is worth it to you.
