Bricasti Design M1 SE - W/ LAN Network Streamer - Version 1.51 V. Denafrips Terminator

Get any DAC that you like and pair it with a Sonare xxxRendu model. I use the microRendu. I will need a second one soon and will get the opticalRendu for ROON Only, for under $1K. This will give you state of the art streaming. You can also use a ratty old noisy computer stored anywhere in your house. There is more to this but it is not difficult to setup.

A lot of people pooh pooh using a regular computer on an audio system saying it is old school. I would never take my computer out of my system. It is not in the same room as the system.

BTW - I still think most DACs have a better USB input over Ethernet RJ45, such as the $13K Mola Mola Tambaqui. Only DAC that I have heard people using the Ethernet is the Lumin DAC, especially the X1 and its Fiber optical input (not to be confused with Toslink).

@yyzsantabarbara Not my experience but ymmv; Ethernet has consistently been the better choice. USB is a flawed interface for high end digital but we are stuck with it. 

Thanks everyone.  I am leaning toward the  Bricasti Design M1 SE with LAN Network Streamer . MSB is nothing short of revolutionary and its modular componentry is probably the solution to the rapidly moving digital technology. I suspect the price for now is out of my budget. I would appreciate some advice on how to set up the Bricasti.  Would I use the Roon Nucleus? Would I need any other components? I need basic step by step which is probably which is probably elementary for most.

You still need a Roon core which is on your Nucleus. The Nucleus can be anywhere in your house as long as it is connected to your LAN. I'll explain how I would do it, there are other ways but to me this is pretty simple. I would place the Nucleus close to my router, it gets the PC which is what the thing is away from the stereo gear. Attach the Bricasti to the ethernet CAT cable then connect the Preamp to the Bricasti analog outs by RCA or XLR. Make sure the Nucleus and Bircasti on on the same network. I'm not sure how you control Roon but I use a Tablet which is on the same network. Open your Roon app and make sure you can see everything and make any adjustments you want. You shouldn't need anything else the Bricasti is Roon ready has ethernet and a DAC. There are a lot of filters and settings in both Roon and the Bricasti it's dealers choice as to what you do with them.

@dpac996 totally agree. Well implemented ethernet DAC is in another league compared with USB and you don’t need all the band-aid solution to make USB work well. 
I think Linn had this whole thing figured out over 10 years ago. I still use my 10 yr old Klimax DS all the time. It’s not as good as the latest DS with Katalyst DAC but it’s good enough that would allow me to enjoy the music without thinking about gear. 
To be fair when I listen to DS Katalyst I get the “holy sh%t” moment quiet often.
