The biggest difference would be switching DACs. And they are BIG! And a lot of them have settings for different filters. Without naming DACs, #1 dac was very accurate but a little on the sterile side. Dac #2 had more bloom with a much more powerful low end. It just depends which one pleases you.
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.
