Similar results on the Tidal test.
However, comparing HiFi Tidal vs. my own 320Kbs ripped tracks, I can hear the improvement in Tidal's HiFi.
What encoder are you using to rip 320 kbps tracks? I find no difference in my own ABX tests between Lame 3.99 at -vbr0 using either Exact Audio Copy or dBPoweramp and Tidal's HiFi (FLAC/ALAC) format.
Now, it has been established that the Tidal listening test here, http://test.tidalhifi.com/, has an audible and verifiably measurable difference between their own HiFi (FLAC/ALAC) and their lossy AAC 320 kbps files. http://www.head-fi.org/t/743658/tidal-lossless-listening-test-whats-going-on-here/15#post_11077298
I can quite easily pass the Tidal listening test 15/15, but I can't pass an ABX between a Tidal lossless test sample and that same file converted with dBPoweramp to mp3. So, I am able to convert from lossless to lossy with no discernible difference identified through ABX, but somehow Tidal is unable to do the same thing?
Edit:
I grabbed 2 of the test files from this post, http://www.head-fi.org/t/743658/tidal-lossless-listening-test-whats-going-on-here/15#post_11077558, and could pass an ABX, even with my refrigerator compressor running in the background during the test. I can take the same lossless file from this test, convert it myself to lossy, and my results are null. Also, I can take my own lossy version and successfully pass an ABX with the Tidal lossy file. Try it yourself. You may have different results. I don't consider myself to be a particularly critical listener, and I think a well-encoded mp3 or aac is indistinguishable from lossless with the music I've heard. Though, I can pass an ABX between the Tidal lossless and their lossy files either directly from the test website or using Foobar.

If you can't pass the Tidal test, when these are clearly shown to be different, yet you claim to be able to hear a difference with your own converted files, I strongly suggest that you take a close look at whatever process/tools you are currently using to rip a CD and convert to a lossy format.
