Hi,
The test I am describing was made years (maybe near to a decade) ago.
I just can remember that we did not touched anything except the file the player/streamer was fed with.
Friend switched from one file to another without me knowing what was played.
I got 100% answers right... except for the 24/192.
I will not go further into this for 3 reasons :
- this is the eternal debate between science and perception... the threads in this site (and in MANY MANY MANY other sites/forums) are already full of this debate and I do not want to start another one with the same arguments being given over and over from both sides ;
- I used to buy stuff after I was able to borrow it and listen to it in my environment with my other components and whatever the specs or measures are ;
- today, I cannot even tell if I am listening to Philips X2 HR, Oppo PM-3, Sennheiser HD700 or Audioquest Nighthawk... let alone telling the differnece between .mp3 and 24/96.
And I am happy with that...
