This should be called, "Most Expensive DAC Survey Ever!"
This survey is just a collection of hi-fi adjectives with all comparisons being to one DAC or another. Plus a collection of what his personal likes in sound are and what sound attributes he values. Why would anyone care?
What is missing is any sense of comparing the sound of each to actual music in real space for fidelity to the original. Seems to me, this is what the high-end should be about.
