Sadly, it means nothing.
I see this all the time with DACs, and had a negative experience with one of those chinese, "giant killer" R2R DACs. This brand has plenty of online representation, so to avoid "damage" and people jumping at me, I'll not say the name or model, only that it costs 800€. I've heard it in a system that was like this: ATC SCM50 > Karan integrated amp > CEC TL5 CD Transport > DAC.
There were other two DACs for comparison, one around the same price (Schiit Bifrost 2 Multibit) and other more mainstream and more expensive (Bricasti M3).
If you blind buy the "giant killer" and ignore the other two, because "diminishing returns", "I want performance, not luxury", "I don't have a 200k system"...you'll end up with a DAC that sounds both harsh, dead and boring at the same time, it literally sounded broken next to the Bifrost, which really sounded nice. Now, the Bricasti justifies the price difference and stomps them, no "diminishing returns" here.
Lesson learned: not everything is that simple, and marketing applies to both the high priced and low priced items, do not let a price tag fool you, it doesn't matter if 800$ or 6000$, listen and buy what you like, not what a bunch of "smart" people told you.
