Props for conducting this, I applaud your curiosity. I see a couple problems worth pointing out.

  1. 10/14 isn't actually very good. At n=14 you're at a 68% confidence interval which really isn't much better than a coin flip. A sample size of 14, missing just one is only 80%, not great.

  2. You really should have a third category of "i don't know/i can't tell". By only have two categories you may artificially increase your score by guessing correctly.

I totally agree. How would I evaluate the third category though?

I have recently signed up for trials of Qobuz, Tidal, and Deezer (already using Amazon Music Unlimited). I stream via a Bluesound Node to a Roksan Caspian amp and PMC speakers - so a reasonably high/medium quality setup. Frankly, I can not discern any material difference in quality between the four and do not hear any improvement from hires.

Having researched the subject further, science suggests that the human ear is incapable of hearing hires. Perhaps it's just me and my older ears.
