Lumin U2 mini vs Mac laptop sound test


I compared and performed a blind test for a listening friend of the following streamer set ups.

1. Router hard wire into Lumin U2 then AES into DAC

2. Wifi into Mac air, out of Mac air via cheap USB cables from my printer and an adapter to go from USB C to whatever USB termination goes into the DAC.

Conclusion.  My friend could not hear a diff.  I "think" I hear a difference but not confident I could pass a blind test. 

Rest of system:

SPL Director DAC/Preamp

SPL S1200 power amp

Kirmuss speaker cables 

Audio Solutions Figure M

I did this for knowledge and fun.  Please let me know any thoughts but I can not see how spending a lot of money for a streamer makes any sound difference.

Gotta admit I’m scratching my head over this one, but goodonya for trying it and trusting your ears.

Me too!!  That is why I had a friend listen for a diff blind.  

Have you heard a significant diff in streamers?

I left all the open programs running on the mac.  Never shut anything down and there was a setting when you are in tidal and switch output on the icon to stream from the mac.  I clicked "more settings" and selected let tidal control volume 

This is confusing to me and I feel like I spent money on the U2 mini when a Blue Sound Node would have worked for much less money??
