I received a GS2 recently and it’s really an absolute steal for the level of DAC you’re getting. The A1 boards still sound absolutely brilliant, and the new chassis is such an improvement over the old one. If you’re at all curious about the Yggdrasil, you should take the plunge. I’ve heard the Modi MB 1, the Bifrost MB 1 and 2 OG, and Gungnir MB A1, and the Yggdrasil is better than all of them. It’s more resolving, with a more 3D sense of space, incredible texture and doesn’t blur or blend anything. I got the version with Gen 5 USB because I don’t use USB and it’s $1699 plus shipping, a bonkers price when you consider these same boards in the old chassis originally released for $2200 IIRC. The new chassis is significantly more svelte and attractive and far far easier to open up for board swaps.
