I was actually considering Chord Qutest even go as high as considering Chord Hugo 2, since I've had Chord Mojo for quite some time and wanted an upgrade. But after reading some comparisons between Qutest, Hugo 2 and RME ADI-2 DAC it does seem RME is considered better.
I've been using RME interfaces in studios for years, but this DAC is their first time entering hifi market, I like the way they were actually thinking and provided useful features such as automatic electric output balance to minimize noise ratio, loudness 20db range of natural human ear frequency curve;
I will try the 5-band EQ to match my room acoustics better later too :)
I buy used piece though, the full price is still kinda crazy, despite people say it's most transparent DAC under 2500$...
