Convert USB to SPDIF


I searched the Forums but didn’t find anything recent on this.  I wish to add a 2010 MacAir running Audirvana Plus to my basement system.  NAS and router are upstairs.  My AVR is anAnthem MX5 channel that doesn’t have a USB input.  What is the best way to convert USB to SPDIF?  I found some cheap converters but would like add something decent...

Try reset on the Node.
It worked on mine.

Or just try the $20 one short term.
You're already sacrificing SQ playing a laptop.
The laptop-Dragonfly-mini cable into the analog inputs of the AVR seems to work o.k.  I had bought a mini cable from Best Buy late yesterday but then didn’t have much time for comparative listening.  I don’t use this system for streaming very much, it’s primarily for video and surround sound music.
  Searching through my pile of unused equipment I came across a Musical Fidelity VLink.  I had bought one when it came out because I had a DAC that didn’t play asynchronous USB.  If I remember it worked for a few days then would sputter during replay.  I think it was a demo unit from a dealer who was going out of business so no refund.  Ultimately I bought an Oppo 105 which had asynchronous USB
Ok, the proverbial dumb question,  I'm reading this post and others, my question. is it always advised to convert USB to Spdif? I'm running from Windows 10 laptop to Schiit Wyrd( decrapifier) then in Project box S2.  Will converting usb to spiff always sound better? Better in all respects. Thank you, Otto
Ottoa63,
USB works great and is often preferred for connections of up to 10 feet.  Mahler123 is running from upstairs to his basement, so SPDIF cabling is indicated.
a further update...I have an Audioengine Bluetooth DAC in the basement system and discovered that it has a usb input, so I run the usb 2 from the MacAir to the Audioengine.  I hardly stream in the basement and frankly mile files streamed from my phone to the bluetooth part of the Audioengine DAC don't sound that different from the PC directly connected to the DAC, so I do either.
