Recommended streamers/servers?

Up to $5,000. At present I have a SILENT ANGEL RHEIN Z1 V2 MUSIC SERVER connected to a PS Audio DS DAC via USB CABLE.

I see the Bluesound Node does not have a USB port.  I’m would be using it with a Denafrips or Aqua dac, please advice.  

+1 for the Cambridge CXN V2.
Outstahding SQ and great versatility and a great price.
I agree quality of the DAC is vital.
I have the excellent Benchmark DAC3B
I went from a tweaked Node2i to an Aurender N100SC. Tremendous upgrade imo.
Highly recommend a DCS network bridge.
I believe that they are recently discontinued, but to be supported for a few more years.
