I just think it's rather silly to claim you're "preserving the original samples" when it's clearly not the case for 24-bit source material.
Are you referring to the Yggdrasil or Gungnir? I think you are referring to the Yggdrasil, as I do not read the "preserving" text elsewhere.
In the case of the Yggdrasil, Schiit addresses the 24 bit issue. From their web sites FAQ page.
If your 24 bit recordings actually have 24 bits of resolution, we’ll eat a hat. And those "32-bit" DACs? Well, they have this measurement known as “equivalent number of bits.” This means, in English, how many bits of resolution they really have. And that number, for most of them, is about 19.5. And 21 is better than 19.5, in all the math books we know.
So I'm not sure it is "clearly not the case". Moreover, I've played plenty of 24 bit material at various sample rates and it sounds really, really, good to my ears. :)
Bottom line though is that Schiit gear isn't for everyone. It's akin to what Jerry has to say about the Grateful Dead.
