Once I had gone through all three DACs I realised I'd ended up with quite a long video. So, rather than that, I split it into 4 videos so if you just want to look at one of the DACs by itself you can.
Part 1: Introduction and The Audio-gd NFB-10ES2
(Note that I mis-pronounced "Resonessence". Somehow an "a" had slipped in my notes about the name.)
Part 2: The Anedio D2.
Part 3: The Resonessence Invicta
Part 4: Conclusion
