I see Archimago has just released his 3rd part where he elucidates the results:

I was one the the possibly five Devialet owners to do the test (the D440 /ProAc D40R in the listing, only 39 amps are mentioned, so there must be duplicates) and found the differences quite small and hard to discriminate , especially between my first 2 choices.
My final vote was 1: C Oppo UDP-205 , 2 : B iPhone 6, 3: D Sony SCD-CE775 SACD/CD player , 4: A ASRock Z77 motherboard.
Echoing maxijazz, I DO like the sound of MQA, so it appears the minimum phase filters win out for me, as I preferred the iPhone over the Sony SACD Player.
In the final analysis of 101 submissions, among the 70% who believed they could detect a difference, the order for listeners > 41 years old (which I am ) was C, D, B, A - most favouring the Sony SACD Player over the iPhone 6. However Archimagio only calculates the vote for the last placed ASRock Z77 motherboard to be statistically significant (@95%), so it is a great pity more people did not do the listening test.
Generally over the years when listening to new equipment for possible purchase at home, I have found the differences to be larger than I heard this time among these 4 devices. Perhaps the limitations of the experiment - listening to music D/A converted then reconverted on a pro grad A/D , then downloaded and D/A converted again before final amplification, may serve dampen the differences between devices. Or maybe D/A conversion has reached the point of diminishing returns. Overall a very interesting experiment none-the-less and thank to @thumb5 post alerting me to the test.
