A good DAC is one that fits one's system and taste, and someone's "best" will not be everyone's choice. The sound of very good, well regarded and expensive DACs may be fundamentally different that one regarded as very good by one person may be totally unsuited for another. The sound of systems where one would put an MSB or Berkeley or WADAX DAC would be a very different system than where an Audio Note DAC would be found. I happen to be a fan of the Audio Not DAC kind of systems.
I've heard a six figure MSB DAC, but, not in my system or even in a system that is a match for my particular taste. How can I possibly evaluate its sound? The dCS stack I heard in a system I am familiar with and liked a lot did not do it for me--it was a touch clinical and I did not engage with the music as much as I did with the Audio Note DAC 5 that was usually in the system. This is clearly a matter of personal taste and "ranking" or "best" are not meaningful concepts.
