Bricasti M21 would be a great choice if rest of your system is up to snuff. DAC’s with built-in Ethernet card makes sense if you don’t want the hassle of separate boxes. Some of us would tell you that separates offers more flexibility and elevated performance.
The price of admission and a component’s worth is very subjective as many here feel a good streamer + DAC setup can be achieved for lot less. I am hoping @audphile1 chime in with his direct experience with Bricasti.
