Succesful ABX of 24/96 vs. 16/44.1

I tried these samples with my HD-590 and X-Fi XtremeMusic in Win7, playback 24/96, audio producing mode.

I didn´t try for to long. On the re-resample i hear the high note synths not as clean as with the native 96kHz resample in the moments the bass beats come. I listened second 11 to 14 in loop. This is quite surprising since i did lately tons of imho serious listening to find a resample setting i want to use with sox. I for myself ended up using not the sox recommendation. I use a slower filter, allow aliasing above the passband and use the lower shaped shibata dither. Maybe it now comes out this wasn´t a to silly choice Of cause i don´t want to enter audiophile territory with this claim but if anyone wants to try it this way when he thinks sox standard has problems and may report here? More likely is we have a problem here with applying 2x dither and 2 times a lowpass at exactly the same spot. One time on downsampling and one time on upsampling. Like said before, on all my tries before i only tried some 24/96 directly to 16/44.1 and did not find any problem. Edit: i never realy understood how the X-Fi works in win7 and what other evil things may interact with it, so you may have an idea. Also i didn´t find a working link to the 192kHz original. I also want to mention i once failed to abx a prepared sample from 2bdecided of "Jazz t the Pawnshop" that he simply created with applying a lowpass to the 96kHz file simulating a resample.
