Would I benefit from a dedicated streamer?

@arafiq  - I am open to everything.  As a rule, I am not an impressionable person, but when it comes to home audio, that totally goes out the window.  I've been down so many rabbit holes.  

I don't quite understand the Sonore Signature Rendu SE Optical, but I've read a ton.  Recently, there was a small device to put in the chain before it for optical.  I read a bunch about that too.  

@jazzman7 - I've had my eye on a linear power supply for my Nucleus and the Sbooster seems to be the best answer.  Thanks for the confirmation.

@ejr1953 - exactly why I asked.  Thank you.

I just replaced my mac mini > Metrum ambre setup with a wolf 🐺 audio Luna R. Its tremendous. I can finally use all the functionality of my DAC8DSD. And the fidelity is insane.  
I should mention I auditioned the U1, and an Aurander w something... they cost Waaaaaay more the luna and cant even touch it. 
 

I initially had my Chord Qutest hooked directly to my Roon Nucleus.  I then decided to give the Sonore opticalRendu a try (with linear supply unit), and I was blown away by the improvement in sound quality.  You can read more about it in this post/thread:   https://forum.audiogon.com/discussions/if-you-stream-music-from-the-internet-i-can-t-recommend-this-...

@andrewkelley -- I checked out Wolf Audio Luna R Digital on their website. It seems that if you want Roon compatibility for streaming, you're looking at $5400. Also, it's not clear whether you need accessories like the connectivity kit to operate it fully. I'm sorry but I don't see how you can claim that it's 'Waaaaaaaay' cheaper than U1.

Also, it will be helpful if you can share more details about your comparison with the Lumin and Aurender. What aspects of SQ do you think are better?

@andrewkelley - I've barely heard mention of Metrum and Wolf, but if those best the Aurender W20SE, that's saying something special.

@hiphiphand - I read your post and the responses when you originally posted, but I now see there is quite a bit more discussion.  It will be tonights "light" reading.  Thank you.
