If you want to play music over wireless network, NP30 would be your choice.
It is better to use Ethernet(cable) with NP30 if you would like to play 24 bit music file.
Have Fun
I have NP30!
The sound is very very good and detail then my CD player!!
I used optic out to my DAC magic, very clear and 3D.
But the RCA out is very flat, the sound state is good for pop music.
I used my Android phone to remote it, very user friendly!
