Would I benefit from a dedicated streamer?

I'm currently running a Roon Nucleus directly into a Chord Qutest via Curious USB cable.   I'm using an Sbooster Linear Power Supply with the Nucleus (fwiw purchased from Upscale Audio) and found that it made a big difference.  Also currently considering introducing a D/D converter such as a Denafrips Gaia into the chain between the Nucleus and the DAC. 

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.
