@smodtactical - The only things I've compared it to are USB directly from my desktop (and a laptop), and Musical Fidelity VLink USB-S/PDIF converter. The BDP-2 is a definite improvement over any of these options (at least into the Schiit Yggradsil). More solid bass and better imaging in particular. The VLink was also a bit unreliable - it seemed to lose sink when the data format changed (sample rate or bit depth).
The SOTM was one of the devices I was also considering, but I wanted something with AES/EBU since Schiit says this is the best way to interface with their higher-end DACs.
