Any owners of Schitt Bifrost 2?

I have the Bifrost II but recently upgraded to another US made DAC, the Geshelli Labs DAYZEE.  I recently insterted it into my system and I am incredibly impressed.  That isn't to say the Bifrost isn't a good product.

I have both. I use a Bifrost in my headphone rig and a Yiggy LIM in my loudspeaker system. The Yiggy was definitely worth the additional cost for me. It added noticeable detail, instrument separation, and soundstage depth. 

It really depends on the rest of your system, the DAC you are replacing, and your future upgrade plans. But since you are thinking about it, I would vote for the Yggdrasil.

I have a Bifrost II/64 and a Modi multibit. I'm pleased with both and Schiit has a lot of value for the money. As some mentioned the Yggdrasil would be a great place to start on the high end, but I have an older CD transport with a R2R DAC (32 bit?) that to me is reference. Unfortunately it's dedicated to the CD so I can't input steaming audio, but I believe there's some modern stand alone R2R's out there.

I would just ask yourself some hard questions. Do you get "upgrade-itis" often? If you get the Bifrost 2/64 you could use it a while, maybe later sell it or repurpose it for use in a headphone rig (if that sort of thing interests you). 

The thing is, if you spend the money on the Yggy now, will you "stick with it" for say 5 to 8 years, or will you constantly be looking at newer DACs that come on the market every 6 months? 

At some point the Yggy will be "long in the tooth" but if it still sounds great who cares? Just to scratch an itch and to set your mind at ease, you could always order a R2R DAC from Amazon use it a while and send it back, just to know if that sound signature trips your trigger better than a multibit (or not). If I had a dime for every time a YouTuber gushed over the "natural tonality, imaging, and soundstage" of an R2R DAC, I'd be able to buy a Yggy instead. LOL. Then again, they all say deep, impactful bass, is not the wheelhouse of most R2R DACs, so there is that. At least if you did that you could avoid having any doubts that you made the right decision for yourself. 

Good luck.
