Any owners of Schitt Bifrost 2?

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. 

 

Hi own a bifrost 2 as well. I agree with @zlone … depends on your systems weakest link. 
 

I really enjoy the sound of it. I use it with an all tube setup (Tzakaridis Aeolos Ultra) and Nola Boxer speakers (streamer is Allo digione Sig) so the bf2 adds nice detail, clarity and separation while keeping the tube sound strong. 
 

If your system is all solid state with a bright speaker then I’d consider something like a chord Qutest.

Don’t forget your source is critical so use something better than PC or Bluesound Node and use a linear power supply to clean it up. 

The two are a lot closer than the price difference would have you think. I have both.

I had the Bifrost 1 Multibit, which sounded great. I moved to a Yggy OG and it blows the Bifrost out of the water…

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.
