You are comparing apples to apples using the USB cable, which will use the clock inside the DAC for both applications. To hear what the N20 is capable of you need to connect the DAC to the N20 via AES or SPDIF. The N20 has superior clocks. If just using USB you could get an N200 with similar results.
Comparing Aurender N20 vs eversolo dmp A8
I replaced eversolo dmp A8 with aurender N20 for digital streaming over qobuz. I compared them playing through native apps. Both feed into Holo may nos Dac over a USB curious cable. Ethernet cable connected over etherregen. Stock power cables feeding from a dedicated 20 amp circuit. Signal going through Luxman amp, 805D4. Luxman is doing pre-amp volume control. Both streamers are broken in.
Result - I am shocked to see that 1/6th price, eversolo is actually sounding better overall. N20 takes control with vocals, however the body of music/instruments is leaner. Not sure why I am seeing this disconnect between powerful vocals and lean acoustics.
I got n20 used, and hence my assumption on it being broken in. Not sure if I am missing something here.. need help from fellow audiogoners..
