Experiences with FiiO D3 v2 and D03K

Blurb: I got some audio interfaces and an A-D-D-A signal chain of a similary cheap Lindy A/D and the FiiO at the end. The Alesis io|2 or E-MU 0404 USB serve as testing rigs for the whole chain or only part of it. This were my first attempts with RMAA and I don't trust every curve in detail, also keep in mind, the "norealcoax" connections meaning that I didn't use a proper coax S/PDIF cable, but which seemed to work nevertheless.

Bad, bad D3 v2
