Does anyone have a digital system that is as involving as their analogue front end?

I think we will be fine for at least 5 years, if not longer. Meaningful R&D at the high end takes a long time.

I just returned from a week holiday and am streaming Miles Davis "Kind of Blue" through the Meitner MA3. I have the vinyl album in excellent shape, but I''m kind of wiped out and it was easier to stream. The MA3 sounds very good. If I weren't comparing the sound to my memory of the album, it would be as if nothing was missing. 

We must remember how good our stereos sounded three years ago or ten years ago or when we were thirty. They probably sounded full and complete. Despite that, due to my audiophilia-nervosa, I will upgrade the Meitner MA3 at some time in the furutre.

In the past couple of days, I’ve finally got my streaming setup sounding the way I want. The final piece of the jigsaw was taking out my Roon ROCK NUC and replacing it with a Windows NUC running dBpoweramp Asset, a UPnP server. In many ways that should have been a backwards step, yet it seems have given me the digital sound I’ve been craving for the past few years. Some of the difficult albums that sounded most harsh in places now sound great all the way through. Albums that I’d been underwhelmed by are now enjoyable. 

Two years ago, I returned to vinyl because I was so dissatisfied with streaming. Then earlier this year, I discovered that moving my NUC and its switch away from a Sky Q satellite TV box gave significant improvement in sound. That set me off on an obsessive quest to try to get the best from streaming.

I have made whole series of tweaks in cabling, position of components, linear power supplies, etc. I had some success, but disappointingly the digital nasties that spoilt my listening always returned. It got better though the nasties were never quite eliminated completely - mitigation but not a solution. Yet now I have bitten the bullet and gone back to a simpler UPnP server and ditched Roon, I seem to have cracked the problem.

What I’ve done so far is little more than a proof of concept, using an inferior NUC and data from a backup ReadyNAS in the garage. I have still to install Windows on my main NUC, reformat its internal SSD and copy back the music files. I probably won’t get all this done before I go on holiday tomorrow. Hopefully, it will be even better when I’ve finished. Nevertheless, I am happy that I’m on the right track at last.

Sadly, notwithstanding its many advantages, it appears that Roon was holding my system back. Ironically, it has been an enforced rest from vinyl due to a faulty phono stage that prompted me to make the critical change. Also, I must thank Google Gemini for helping me to plan everything and providing clarity.

PS. Another couple of changes made since may have helped, too.

I have switched off HDMI in my Linn DSM. There’s now no HDMI connections made via it. I have installed a Toslink Optical Cable for sound from the Sky TV box, which isolates it electrically.

dBpoweramp now unpacks the FLAC files to WAV, saving the Linn DSM a bit of work.

@newton_john roon sound quality has been an issue gor me for years. But dince the major update they deployed at end of April, it’s been more or less solid. 
I don’t use any upsampling or EQ features in Roon. The core runs on nucleus one. Like I said it’s been good for about a month and a half now.

Give jplay a try. Doesn’t need a computer to run on. I find sound quality with jplay to be excellent. Easy to configure. You'll be up and running in under 5min.
