Audiofools don’t like blind tests.
I once took a Chinese DAC board I’d bought from eBay to a “bake off” (not sure what you call Hifi meet-ups in US?).
It was hooked up into the same Pre amp as a fancy milled Aluminium Chord 64. Track played & Preamp selector switched from one to the other.
12 guys & 2 women in the room.
The only two who said they heard a difference were the 2 women.
Guess which they preferred?
It wasn’t the Chord...
There are so many unmentioned variables within your anecdotal story of a "blind test".
If you're going to make a statement, why not put in the effort to describe the rest of the system components, how the DACs were connected, what source was used for the digital signal and with what connection, et al.
Most audio fools don't take the time to do the work to even know how a blind test is conducted, resulting in meaningless anecdotes like yours, containing information of no value to anyone.
