I’ve had the M3 for about 6 weeks, so it’s good and broken in! The M3 is my first dac so I can only compare it to an Oppo 203...which is no comparison really!! I think it’s sounds great in my modest system. It would definitely be the highlight!! I would say it’s very musical! Sometimes I catch myself going holy crap that sounds good!! I have the network card and have been running Roon in to it over Ethernet and using it with USB as well. Its hard to tell the difference sometimes. I upsample to Dsd 128 and then I’ll play it straight up and both are great! I just added some GIK panels and that definitely helped the room! Its a great looking machine and the remote is a chunk of aluminum. I liked dealing with the guys at Bricasti, and that ultimately led to the purchase! I’ll try to answer questions if someone has one!!
