Why dont more standalone DACs come with ethernet???

How does it sound?
The only important thing to me.

I have a Bricasti M1SE with the ethernet module. After the MDx board upgrade, and in my humble opinion, ethernet is superior to USB.

It seems like there are quite a few DACs with built in ethernet these days: Bricasti, Mytek, PS Audio, Lampizator, Lumin, MSB, Simaudio, Naim, Aurender, Auralic, Krell, Ayre, Hagel, Mola Mola, dCS, and the list goes on.

PS Audio has done this for a while.  That's one thing that attracted me to the DSDjr.  I am now curious how something like an Innuos Zenith would sound compared to the PS Audio Bridge II.  Extra digital cable, extra power cord, extra rack space - significantly more cost. Is it six times better than the $1k Bridge II?  That will be an path for me to explore in the next couple years.

While the PS Audio w/ Bridge and the Innuos can both be streaming end points, the Innuos differs in that it can be a Roon or UPnP Server and it has the ability store music locally on an internal hard drive.

If you don't run Roon or store files locally on a computer/music server, then you might not benefit from an Innuos.

The DSDjr is a Roon endpoint and a UPnP Server. I use Bubble UPnP. But your right, no storage. I think the only way to really know is to buy some streamers, connect to the DSDjr and compare to the Bridge II. Unfortunately it sounds expensive :)
