@jakesnak,
Thanks for your kind feedback. Without a doubt N10’s SPDIF and AES/EBU audio outputs are superior over its USB output due to signal from these outputs being regulated by one of the finest on-board OCXO clock. I’ve used both of these outputs for a very long time with DAC’s prior to acquiring DA2.
With DA2’s meticulous and superb implementation of DSD and USB, I started listening to high resolution files than be content with files upto 24bit/192kHz resolution. For the sake of convenience and simplicity (one less $$$ digital cable) I stayed with USB as it supports wide variety of resolutions without the hassle of switching back and forth between PCM and USB.
If you’re concerned about missing out on high resolution due to non-MQA support, sign up for a trial with Qobuz. I have dropped Tidal last year after auditioning Qobuz. To my ears, their high resolution SQ is superior to Tidal (even with full unfold of MQA files).
IMHO, DA2 is one of the finest sounding DAC currently available on the market.
Enjoy!
