Great thread.
Just picked up a lightly used MA3 on Audiomart. Arrived today but I am still waiting on my new integrated and speakers so all I can do for now is put some “settling hours” on it and watch it stream.
I am wondering if anyone is using the MA3’s internal network streamer directly via Ethernet from your router/switch, and if so, your opinion on the sound quality and also vs using an external server/renderer/streamer via USB into the MA3?
