Schiit Yggdrasil DAC, why did they change it ?

I sold the Yggdrasil twice hoping for something better before i bought it again for the 3rd time. I have the OG and it is end game for my specific tastes, especially when i run DHertz MasterClass files through it.

I have audited everything from Berkeley, Holo, Nagra, Aavik, Vermeer, MSB, Mola Mola, etc on one of my rigs....not interested, but, doesn't mean you won't be.

I thought the More is Whatever version and the full AP reports were just a JStoddard/MMoffat answer to some 0.0000001 THD chasing scientists who are forged in the flames of another forum.

@decooney thanks for that input. Nice to know it (the Bifrost 2/64) isn't a "rolled off" dark sounding DAC. I'll take all that under consideration for its price point of under $1K. Other reviewers have mentioned that to "best" it, you do indeed have to go up the food chain to something like a Yggy, Holo, Denafrips, or LAIV, but those are $$$ more, and I'm not sure my system (or my old ears) could hear a demonstrable difference.  I find it appropriate then that Schiit offers the 2/64, and the next step up is all the way to the Yggy (in its various incarnations) to get a solid difference in audio quality. 

@moonwatcher not dark, that's for sure. I had come from some warmer dacs prior, and including an upgraded tube dac [different cap and tube options] too which was open but warmer too if that makes any sense. I needed a fill-in dac to use while I was deciding and eventually having another dac built a certain way (in the meantime) is how I ended up with the Schiit Bifront 2/64 multi-bit dac for a year or so. Also, I just wanted to try it for the entry price, and used it as a backup reference dac to other dacs. I found it to be quite neutral, open, with added nuance to the depth of detail in fact. Was not lush though.  Just plain neutral maybe. I'd rotate it in/out, and would say it's a bit more detailed than some dacs, coming with that newer TI multi-bit chip set in it, even with the filter switch.  Agree, if you want that extra finesse to the sound, I could see where many step to the Yggy. For me, I did want a little more warmth with a bit more lushness to the sound, and moved on. 

For Moonwatcher,  I have the Bifrost 2/64, and my hearing also rolls off at about 12.5 to 13 kHz.  I love the Bifrost, although the only other DAC I have experience with are those in my iPad Pro, the AQ Cobalt Dragonfly, and the ESS DAC in my Schiit Jotunheim.  Perhaps due to my hearing loss, I don’t notice a roll-off.  My  LPs—such as Sheffield LPs of the 1980s do sound more “brilliant” when the appropriate content is there, but the Bifrost, IMO, does a very good job.  I am particularly pleased with the imaging/soundstage (both lateral and depth) and tonal qualities of the instruments.as reproduced by my Rogue RP-7 tube preamp, Odyssey Kismet (upgraded almost to Kismet) SS monobloc amps, and Fyne F-702 speakers, augmented by a pair of Rythmik F12 subwoofers.  I’ve considered stepping up to the Yggdrasil MIB, but I wonder how much improvement I would get for three times the price.
