Tidal has a similar test[1] (though only between 320 and lossless - no 128 track). Now, it's trying to sell you their high-quality streaming option, so I would take the results with a bit of a grain of salt as there are a number of ways their bias could have affected the results (for example, they could have cherry-picked tracks that didn't encode to mp3 as nicely). However, the format is much better than this one: the two play in sync, and you can seamlessly switch between A&B as it plays. I found it much easier to find subtle differences between the tracks that way over having to restart the track each time. But more importantly, that test format preloads the tracks. In this one, some of the lossless tracks took several seconds to load for me, which completely killed its double-blindness. [1] http://test.tidalhifi.com/ http://test.tidalhifi.com/
