I plug hd800s into samsung note8. I try 1st time and find out that those sample are not masterpiece quality. And, all of them is not familiar to me. That make difficult to point out what is what. Example some sample when I select what I think/hear less distortion, it is 128 sample. Wav sample is more distort, but it is result. So, I test again with my "adjustment" : that sample, for choose correct uncompress, I will base on more distort. Below pic is the sample had wrong result 1st. But then 10 times later I choose correct sample quickly what is 128, 320 and uncomp in order. Very first second 128kbps left a longer tail. So 320 and uncomp remain. 4second later, uncomp has more depth on piano than 320. (I was thought this tail as "more detail", as a "content" of instrument bcs I never heard) I think that is some reason for case someone can feel the difference but can not point out what is what.
