My Yggdrasil is living up to the hype. I'm using it with FLAC only from either my server via WiFi and through JRiver or, primarily, via Tidal using the Amarra interface. I'm strictly going, for now, with USB out of my Macbook Pro to the Yggy. I'm not aware of any glitches.
Schiit's stance on Redbook (versus other formats especially DSD) is well documented. I'd head over to head-fi.org and read the reams of info, reviews, opinions both on the Yggy and the company (Schiit) itself.
With shipping and tax (for Californians) it will go over the 2K by around $500.
