Server for Bricasti M1/3

Thank you all for your insights. It seems the only direction is up. 

I run a Bricasti M12 also have a M3 hooked up for demo. I initially started using Roon on a MacBook Pro and worked fine, had to reboot the Mac every now and then but no major issues. This all running wireless via a XFinity "POD" via an Ethernet connection. Then changed to the dedicated Roon Nucleus and just WOW. Cleaner and more detail and better depth, a BIG improvement.

(Dealer disclosure) 

I have a Bricasti M3 with network card connected to a Small Green Computer sonicTransporter i5 with 4tb ssd.  Works and sounds great with my setup and in my room.  I experienced problems when I attempted to run Roon core on my MacBook Air.  All issues disappeared after moving to sonicTransporter.  

Antipodes S40 and K41 have ethernet outputs and are superb with the Bricasti.  I haven't had the 41 here as it is brand new but had the 40 here for most of last year and used it with the M3, M1 SE and Weiss at different times.  It is a great match and will be a HUGE improvement over your Mac.

The S40 is a good, high powered server that you can add too through time.  They have an upgraded LPS, clock, etc...

The K41 is intended to be the best, standalone server with the best ethernet output available.  It has Antipodes better boards and best tech with an on-board LPS, etc...  

Full disclosure, I am an antipodes dealer but I actually have direct experience with this combo and it really is superb.
