I use kernel streaming in JRiver 19 running on Server 2012 and Audiophile’s Optimizer.  I use a Sotm USB card from a home built Intel server motherboard feeding the AMR 777.  It works great. PS I use core mode in Server 2012.

I own a Bidat also and I am interested in buying a Legato USB converter. Did you guys come up with any answers to these questions. I would like to use a James Moray cable with foobar.
