Roon Power Supply

@thinman2 - Are you connecting the Roon Nucleus via USB directly to your DAC (with this setup the PS would likely make the most significant difference), or using another Roon endpoint on your network?

@thinman2 Good on moving forward with the Farad. Adding a linear power supply to your Roon Nucleus will reap benefits. 

Since you've taken the first step, invest in a quality aftermarket DC cable. You may also want to play with the AC power cable to the LPS.

Interesting that Farad offers a choice for the AC receptacle and Fuse.

bill_k. David_ten.  As a  vinyl guy I'm taking baby steps with streaming. Presently I have the Roon streaming to a red Dragon Fly with 2.5mm plug and splitter  to RCA into Pass Labs XP30 3 box preamplifier to Pass Labs Monoblocks into Klipsch LaScala.  I have a Tidal $20 per month account.  Undecided on DAC and whether or not I will require it to have  Roon and MQA . Hard to find a Room, MQA DAC that doesn't have headphone amp, preamplifier, line stage or other circuits I neither need nor want. Appreciate any recommendations on DAC. Once I decide on a DAC, I will seek everyones advice on cabling.  Thanks everyone for the help.  Oh, I opted for the upgraded receptacle but not the fuse.

@thinman2 Since the Roon Nucleus is Roon Core only (correct me if I am wrong), you will either need a standalone Roon Endpoint/Renderer OR an "audio device" that offers Roon Endpoint/Rendering.

You will also need to decide between a networked solution or going direct into the "audio device" via HDMI or USB.

For your DAC, I suggest that overall performance and sound quality drive your choice AND NOT whether it is MQA enabled (you get the first MQA unfold via Roon, regardless).

I’ve achieved terrific performance with both: a separate Roon Renderer/Endpoint AND with that function housed internal to my DAC.

The Nucleus (or NUC running ROCK) can be connected directly via USB to a DAC. This isn't recommended by Roon for the best SQ, but if your DAC does a good job of rejecting noise from USB, or if you use some form of USB re-generator, it will work fine.
