The Yggdrasil DAC is absolutely astonishing. I have 494 hours break-in logged at this time. During my listening sessions I have already started taking notes for my review. This past several of days the Yggdrasil has floored me more than once. The authenticity of instrument sounds and voices is so realistic and natural it is almost uncanny. I continually find myself awestruck as I listen. I am pulled into the performances every single time. I have not yet compared the Yggdrasil to the Esoteric K-01X in the studio system. I'll get to that one of these days, but I swear the Yggy is neck and neck with the K-01X, if not superior, in its ability to present music in a genuine, captivating, and immersive way. No matter the price, the Yggdrasil is a serious competitor with DAC's way up the digital converter food chain. Its performance level has reached a place where the accurate representation if sounds can be startling. They are that real and that thrilling. Its price may make the Yggdrasil appear an underdog, but be forewarned. This DAC kicks ass.
