Streamer/Server to replace Innuos Zenith

Lumin X1 (has separate box for pwr stuff) streamer/dac plus roon nucleus.   Looking for a really good tube preamp.

then i done. 

Rockna Wavedream NET.
Not that popular of a server due to lack of proper marketing and manufacturer not trying to expand production numbers, but it did beat my Aurender N10 which is now gone since a year.
I actually got their dac first Wavedream signature, then got the streamer. I was shocked of the server performance and i believe its even a better value than their dac!
As a bonus, its doubles as a great CD player (totally isolated from server section- for ripping you have to attach an external CD drive)

@jmphotography, when I really started getting heavily into streaming music when the pandemic hit almost a couple of years ago, I was looking for the simplest plug and play solution that also sounded great, where the updates were automatic, and one where I could just pick up either my iPad or iPhone and start listening to music without any fuss or delays. At that time I too was using a Qutest as my DAC, which I fed using my MacBook Pro as my ROON core via a AudioQuest Diamond USB cable. When I asked my audio gear dealer if I should get my laptop out of my listening chain he emphatically said “Yes, do it right away”. So I looked around his store where he’s got several hundred thousands of dollars of high-end gear for his customers to demo, and I asked him what did he use for a dedicated streamer/music server? He pointed to a ROON Nucleus and said, “We use these because they’re foolproof and they sound great”. I ordered one that day and I’ve been happy ever since. Here’s a link to a comparison of the ROON Nucleus and the Innous Zen Mini Mk III. https://www.stevehuffphoto.com/2020/07/04/roon-nucleus-review-as-a-streamer-vs-innuos-zen-mini-mkiii... Since then I’ve traded my Qutest for a Chord Hugo M Scaler and TT2 DAC, and I’ve added a network switch and an Ethernet filter between my router and the Nucleus which has made everything sound simply sublime. One upgrade that I did with the ROON Nucleus, as I’ve also done with both M Scaler and my TT2, was to put power it with an Sbooster LPS(linear power supply). Never underestimate the importance of having clean power feeding your system. This link to Moon Audio is great because it goes over everything you’ll need to know about the ROON Nucleus. https://www.moon-audio.com/roon-nucleus-faq/

Cary Audio makes two streamers. The DMS-700 and DMS-550. They still have some DMS-700 units that have the AKM-AK4499 which was the best chip made before the fire. You can't get them anywhere else I've seen. It is also a great unit with Roon and iOS built in.

My Roon/Qobuz based digital front end has separate processors for server, end point and DAC and it's stable. Right or wrong I credit the stability to processing headroom and AuraLic sfw/hdw integration. I also suspect AuraLic's integration is the most critical link when it comes to stability, my Aries has not been power cycled since its last Lightning DS upgrade and it's still playing well with others. I do have to keep an eye on Roon upgrades because they tend to introduce undocumented features (bugs) but beyond this I have good stability. I also balance DSP across the Nucleus and Aries to avoid saturating the processing capacity of either device.
