I'm not sure how sustainable model this is.
I went through their audio faq and it surprised me they lower the loudness of the tracks so it doesn't exceed -0.7dB true peak, stating some players "refuse" to play such a CD. That's strange, because for ages people have released CDs with clipped audio or -0.1dBfs peaks, absolutely not giving a single f about true peak and there was no problem.
The vinyl audio guide faq is spot on. That said they mention they use some new technology to manufacture vinyl, but don't provide more details.
