Digital Upgrade Recommendations

…or better doing away with the Nucleus (and possibly Roon as well) In my setup InnuOS Zenith Mk3) Sense 2.08 sounds decidedly superior to Roon and the Nucleus isn’t the quitest server to start with… Hence my Intona Isolator recommendation

…and by the way: I started with the Etherregen on its own, then added an Antelope 10m clock via Shunyata Sigma clock cable, then added a Zerozone 2020 Benchmark LPS on a Nordost Brahma PC, then switched to a sterling silver DC cord. Each step is easily demonstrably audible. The additional equipment is a multiple of the original Etherregen purchase, yet I wouldn’t want to miss it.

Going optical post server is optimum way to go. Read John Swenson's papers, thoughts on streaming in general. @yyzsantabarbara  pointed to one thread. Here's another about everything under the sun.https://audiophilestyle.com/forums/topic/62477-john-swenson-tutoring-paper-considerations-regarding-usage-of-external-reference-clocks-etherregen-and-other-sine-vs-square-impedance-cables%E2%80%94and-a-money-saving-surprise-at-the-end/

Swenson likely the preeminent expert on audio streaming.

one thing is definitely true, you start down this path, you do end up with lots of little boxes, cables, extra power supplies...  that aspect bugs me, but hey, at least at present, this is the drill to get the sound to be really really good... 

Thanks guys for all the inputs.  It is a slippery slope you can go down but I’m primarily a vinyl guy and really just wanted to get advice on which of the three well-regarded upgrades would give the best sound improvement for my digital setup at that price point.  Sounds like the DDC is the way to go.  At least for now!
