My experience is the opposite. I used both and prefer the N10 for its excellent sound quality, ease of use and the Conductor App. I also compared the N10 using its USB vs. AES/EBU input connections and prefer the AES/EBU for a slightly better sound quality. I also use its balanced outputs to my DAC. Aurender constantly updates their application so new features are available. Aurender customer support is also excellent, if needed.
There could be other reasons in your system that make the MAC sound better. I do not know and prefer not comment on cables used, environment and a host of other factors.
Everyone is this hobby has a different opinion so I would not worry about it I suggest you enjoy the music and forget about this comparison.
