Would I benefit from a dedicated streamer?

I have a Roon Nucleus Plus connected to a PS Audio DirectStream DAC and the SQ streaming Qobuz is awesome.

I'm not sure I'd put another device in the path.

OP: If you're open to other options, take a look at Sonore Signature Rendu SE Optical -- made in USA. It's based on their opticalRendu product, which I own and can vouch for.

Any of the 3 you mention will be a better sounding replacement for your Roon Nucleus

@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.
