Does adding a steamer to a Roon Nucleus / server improve audio output

I have a Small Green Computer SonicTransporter, which is essentially a Nucleus. I use it with a Sonore Microrendu streamer/endpoint going into my DAC, and it's fed by the SGC. It’s an improvement. You could step up to the UltraRendu or Optical model which is said to be an improvement but I like the MicroRendu just fine.

"The microRendu is an audiophile microcomputer music player with Ethernet input and USB Audio output. The microRendu utilizes a proprietary printed circuit board with only the essential components. The microRendu is small and lightweight. Connect the microRendu directly to your USB DAC via a USB cable or hard adapter eliminating the need for a USB cable. Don’t let the size fool you the microRendu has been designed to take into consideration all that is important to USB Audio. The microRendu is easy to configure and can accept audio streams from several digital sources."

If you are looking for high sound quality it is a requirement. PCs are very noisy. My first streamer was a Auralic G2, then I moved to Aurender and now own their flagship W20SE. Each a major improvement. Now my digital side is as satisfying to listen to as my analog end. I hesitated buying a streamer for well over a decade, my various devices and Apple notebook running on battery seemed sufficient as it was just sending out bits… I was completely wrong. It is just like analog, all components matter, but the closer you are to,the source the more they matter. Put a bit of noise in the source and you just amplify it. My system has never sounded anywhere as it does today, and my streamer and amp are the most expensive components.

…only if you play mostly sexy soul music😇

The owner of Roon, Danny, says it may or may not.
