Schiit Yggdrasil DAC, why did they change it ?

Back in 2017 Schiit Audio introduced a DAC they called a Yggdrasil. It was well received to say the least and The Absolute Sound said after a break in period it sounded as good as any DAC. Some time ago they changed it and right now there are 3 versions available on their website. They are Less is More, More is Better, and GS2 (Garage Sale 2). The prices are $2299, $2699, $1699 respectively after the recent price increase. The difference is the first 2 use gen 2 cards and GS2 uses gen1 cards. Each DAC has 4 of these cards and the gen 1 cards cost a lot more ( Schiit says Uber expensive ). The GS2 uses cards they got when people upgraded to the new DACs and they kept the gen 1 cards. Mike Moffat said in an interview he did not want to have a product that cost more than $2500. I think the original just became too expensive to build and that’s why they went with much cheaper TI cards. They claim the new DACs sound better after they did complicated math and engineering. I think the original sounded better and the GS2 is at least as good as the new ones. I’ve seen "want to buy" ads for the original. Having said all of the above I want to say I’m a big fan of Schiit Audio and use their Freya+ preamp and the GS2 DAC. The rest of my system is a PSAudio S300 Amp and Herbeth 30.2 XD speakers.
