Setup, Sonore Sonicorbiter & NAS

My current setup consists of laptop accessing local HD files, running Roon, USB thru JitterBug to irDac asynchronous USB, irDac via Coax output to Pioneer SC-37 receiver.
Is there a better way to set-up/connect?

Would adding a Sonore Sonicorbiter provide any additional benefits?

Who are the recommended Roon partners that provide NAS capabilities?

Thank you,
