If I had opened the same thread talking about a Hi-End stereo (a system which I also own, and probably of a much higher level than that owned by the majority of those who replied to me. Just as are professional all the measuring instruments present in my laboratory), then my judgment would suddenly become worthy of consideration.
As I and other already said, you are totally mistaken. Why would the judgement be different because you own XYZ? It’s subjective, no matter what you own or who you are. In general we really don’t care what something costs either. Objective performance is what matters. Many very high priced products were thoroughly thrashed because of bad performance, while elsewhere they were praised for their apparent fantastic performance.
subsequently gave the complete characteristics declared by Cirrus for this DAC, which are objectively remarkable.
No, you didn’t. You just copied the data that the Chinese produced pages show. The actual but limited Cirrus documentation shows different figures for the chip. Who is right, I don’t know? But in general I find these Chinese product pages to be lacking in detail and accuracy. In this particular case for instance, it mentions DSB instead of DSD. Whatever else might be wrong, who knows? If the Cirrus document is still current, I also don’t know. It’s basically the only official source of information about the chip that I could find at this point in time. Time will tell…
What I do know is that I don’t expect any miracle performance, other than maybe that it is able to drive some headphone a bit harder than other solutions. Which admittedly can be a huge plus.
