Bricasti M3/M1SE

I don’t believe so.  There may be a way to override and load different software but I don’t know what it is.  Nucleus is a Roon device.

The Antipodes S30 (pricier I know) does have the flexibility to use a bunch of different software packages.  

So, I am a Bricasti and Antipodes dealer.  I just sold a used pair of CX/EXs and they are good units and have my demos of the M1SE and M3 on the way. 

The reality is, the network card in the Bricasti only replaces the EX.  You still want a server.  Lots of people run direct from a PC/MAC into their DACs and are happy.  Most of the time, they have not tried something like an Antipodes server and are unaware of the difference it can make.  

You will find even a dedicated PC will be a step down and will be noisier.  I offer a 30 day return policy without restocking on non-special order items.  I have had exactly one server returned in more than 2 years, and that was only because the customer decided quickly to move up from a K40 to a K50.  

I had a Dell Tower dedicated just to running Roon core and nothing else hard wired to my network.  A Roon Nucleus was a big and noticeable step forward.  The CX will blow your PC out out the water.  Not what you want to hear I am sure but PCs just have too much going on, have noisy power supplies, etc....

I have not tried tvad's suggestions.  They might work.  Not sure.  Certainly can't hurt.
