Point of higher priced streamer?

@paulcreed not sure what you mean with 'noisy', but, ime, some systems pick up noise originating from the MacBook wall wart power supply. Good conditioners (Furman, Shunyata in my case) reject this noise entirely. You can also run the MacBook for many hours of battery power alone (no audible difference in my case, but if that wall wart causes trouble ...) Of course you don't want any other applications like messaging, email etc. run on that macbook.
Re soundstage: Roon seems to provide for perfect time domain control of the digital data stream, and, again, ime, imaging is superb. Somebody else here stated that they prefer wired ethernet connection over Wi-Fi. Again, I believe this depends on the quality of your home Wi-Fi system. Multi-channel mesh systems have very high capacity, no drop outs, etc. and, again, in my experience, streaming from a MacBook via Roon to an OPPO 205, with the MacBook receiving signal via WiFi and sending signal to the OPPO via WiFi, sounds superior to any variation of one or both digital connections by ethernet cable. In the end, Ethernet cables are not that well shielded and you would expect some RFI/EMI contamination of the unit they are connected too, but that is speculation on my side. WiFi of course provides for complete electrical isolation.

you must run usb to get the Best out of a dac only usb ofers asyncronous data transfer which cits down on zransmittteed jitter

Actually this is not entirely true. While most do, some DACs do not use Asynchronous USB, but isosynchronous; also not all DACs sound better from a USB connection depending on how the grounding and power rails for the USB interface have been implemented with the rest of the DAC board, not to mention variations in the source of the USB stream.

There are plenty of DACs with SPDIF/BNC/AES inputs, which when matched with a properly clocked (low-jitter) SPDIF output, will perform better with the same files compared to a USB delivery. It really depends on the DAC and application.

@ironlung  I for one am enjoying your posts and learning quite a bit.  Thank you.
