too bad our esteemed member @tvad no longer posts here
he has had the m3 for quite a long while, loves it in his wonderful audio note system, and i think just very recently moved up to the m1 model
that said, if my memory serves correctly, he was a very strong advocate of using the network card input for his m3
if you do a back search using his username and see his old posts, he commented numerous times on the m3, and what he did to get the best sound out of it...
