Nucleus, is there a better alternative?

You are correct, that's why they have audiophile switches, supposed to limit noise. I did try audiophile switch, preferred router with no switch, router powered with lps. Guess I'm lucky with no need of switch in my setup, why add another component if not needed, addition by subtraction.

Having said that, I assume audiophile switches superior to regular switch, this based on positive reviews of many.

K41 is a nice solution.  It offers an extremely clean ethernet input.  I have tried it as an alternative to the Nucleus + as that is my other server.  This will be an improvement as the processor is quieter and the direct connect from Antipodes to X1 should provide a cleaner connection than just about anything else.  

I have a customer who is running one (K40) with a Weiss and it is extremely effective.  

Incidentally, I am an Antipodes dealer and a Roon dealer.  

My understanding is that an LPS on a Nucleus or Nuc ONLY makes a difference if you’re going straight from the Nucleus or Nuc into your Roon Endpoint by USB.

if you’re connecting to the endpoint through the network, it makes no difference.

@jumia, a Roon Nucleus with a good LPS makes sense if you’re all in on using Roon like I do to just pick music tracks from Tidal and Qobuz. With my Apple iPad and iPhone it is super easy to navigate through tens of millions of songs and albums at the touch of my finger.

I keep the signal path from my router to my headphones as simple and short as possible. To me what’s more important than having a fancy music server and/or streamer is having clean power running through your system, and eliminating as much RFI and EMI as possible from getting into your mains. That way you can have an inky black sonic floor that lets you enjoy the soundtrack from my daughters favorite movie right now. Disney’s Lightyear.

Regarding the Sonore opticalRendu and opticalModule Deluxe.  We continue to have opticalRendus in stock. The opticalRendu is undergoing a redesign which we do not yet have a delivery date for.  The new opticalModule Deluxe is in production.  Once we have a firm ship date, will will let everyone know.
