Don't worry - I am just naturally sceptical .
The reason I questioned the timing is that in your last test there were several results under 10 seconds (1 was actually recorded as 5 seconds) - 14.55.22 to 14.55.27. That barely gives enough time to hear the track and make your choice. Just seems 'questionable'.
I owned the B2 previously - so I know what they are like. The fact that you use 24/96 will make no difference to the test - especially as the recordings you compared were only 16bit anyway. I can't speak for the E17, but I have owned several Fiios in the past - none were particularly 'resolving'.
If you were able to discern a repeatable difference .... well done. Unfortunately there is no prize . Is there any particular part of the recording that was easy for you (ie at what timestamp)? Just interested. Won't make any difference to me (my ears are not that good) - but may be interesting to others.
And your English is perfectly fine - no need to apologise.
