You guys seen this listening test by Archimago last year? I just found out about it. Pretty damning evidence against “Appledongophiles”, though they themselves of course would never admit it. 
There was a trend towards preferring the objectively higher performing and more expensive devices: $20k Linn Klimax DSM/2 > $3k Linn Majik DS + Dynamik Power Supply > $10 Apple dongle among all 86 listeners who felt they heard a difference. (Section IV)**
That trend towards preferring the Linn streamers did seem to hit [statistical] significance when we consider those who had more confidence in their ranking and thought it might be at least “worth spending money” to upgrade.
This finding I think is also a nod to the idea that in a blind test, audiophiles do overall prefer higher-fidelity gear which correlates to better objective performance (like the 1kHz 0dBFS THD+N), at least in this test.
