I'm close to taking the plunge on an NDS/UnitiServe SSD/555PS so I can digitize my CDs and network the library. My current setup is 202/250.2/HiCap/CDX2/Sonus Faber Cremona Auditor M, but if I get the NDS, I will probably also at least upgrade the preamp to a 282. I love most aspects of my current system and it's fantastic on most kinds of music, but on some denser rock music it can sound a bit congested, which is unexpected. More broadly, I love the PRAT, accuracy, and many other aspects of Naim, including the simplicity of the upgrade path.
Since I would be more than doubling down on Naim, I thought I should at least consider what else is out there. I've listened to some very nice gear, including Soulution, Pass, Constellation, AR, Magico, larger Sonus Fabers, and Devore. I have to admit that I've heard some fantastic sound, and in some cases I've been enveloped by music in a way that made me think I never wanted to leave. I've also heard some very expensive equipment that sounded amazing in some ways but the more I listened sounded kind of mushy and slow (even as it enveloped me...).
I'm curious to hear the perspective of anyone who has drifted in and/or out of Naim or of anyone who has been dazzled when continuing to upgrade with Naim, as well as anyone's thoughts about whether the congestion I sometimes notice on denser music is typical to Naim on certain source material (perhaps because it's so revealing) or my speakers (maybe larger or even just a sub would help?). Again, I've been very happy overall with my current system, but notice that it doesn't sound "itself" with all kinds of music, so I just want to consider all options before I plunge deeper into the pool. Regardless, I'm looking forward to the next steps!
All input welcome - thanks!

Hi - although not for complete beginners and a little knowledge is required - after all that was the whole purpose of the Pi - there are some quite basic guides for setting up Asset and MinimServer for the Pi on their respective web sites.
I'll dig out the guide links later - as both are mentioned for use by Naim I am sure such links wont be an issue

I was kind of hoping there would be a page out of a 'cookbook' available, rather than the whole book.
To make a... You will need... for 20mins .. then serve with chips (of course!) I' m no idiot, just never used one before, a bit like "I've never ridden a trials bike, but I do have a minibus license."

That would be great, thanks Simon. Don't make it top priority, I'm in no hurry!

The Raspberry Pi discussion is great, as to some extent it's a metaphor for the whole 'this digital music thing is so complicated' process a lot of us go / went through.
As I've written before, I bought a uServe because at the time, this whole digital music thing seemed so complicated, and I did not want to shell out $15,000 (ahh the good old days) for a hi fi that needed fiddling with to work. I did not want a computer in my living room. I bought the uServe because I knew it would "just work." Fast forward . . . I now know a whole lot more about this digital music thing, am perfectly capable of installing Minimserver on a nas (although I've yet to really optimize how it serves the data to the Naim App), managing my own metadata for downloads, etc.
I dare say most people can make the transition I did (I'm not all that smart), but many will get value out of something that "just works" on Day 1, right out of the box.
If/when I want a project, I may buy a Raspberry Pi and learn a little. I have a friend in the area who I know would help me with it when I get stuck. (He's the guy who looked at my uServe backup folders and said they probably aren't working because there are spaces in the names; brilliant.)

Great stuff - my next project is a very low power server project so these will be useful.
James
I am using a Pi as a file server and backup system. It is basically a Debian/GNU Linux system and can be set up quite straightforwardly. I also run minidlna (a UPnP server) but I stream music over the LAN only occasionally and not for dedicated listening.
For dedicated listening I use a fanless low-power Fit-PC microserver. If you google tinygreenpc you will find newer models (Fitlet and Fit PC4) with even lower power consumption (than my Fit PC3) and certification for Windows, Linux and, depending on the model, Android. They are well built (the Fit PC line uses a thick aluminium case as a heat sink) and absolutely silent.

James, halfer3o and Bart - here are some basic instructions on installing these media servers on the RPi. Asset is probably slightly easier - but neither is particularly hard to do
Asset:
https://forum.dbpoweramp.com/s...y-Pi-Asset-Specifics
MinimServer
http://minimserver.com/install-raspbian.html
Both work very well - and with the newer RPi2 the navigation and search performance is superb with my 20533 Tracks, 1324 Albums.
I have both transcode FLAC and ALAC to WAV in real time. (but I would not install on same RPi / Server as there are technical IP Port config changes to do if you have both running on the same RPi / Server)
I mount the NAS as a SMB read only network file mount - and voila

Very different. Japanese designers tend to prefer a slightly warmer presentation. I found the music to be well-rounded and more 3-dimensional, yet with similar drive and punch.
Of course, the gear looks completely different!

Hi it will be interesting, however I think you will be at the mercy of the PSU quality and impedance to the SPDIF transport clock and how well the isolation and regulation is around the transport clock. I am not sure it would be best to rely on the USB PSU for such activity for critical usage.. Can you power the SPDIF transport clock via a seperate PSU?

I went for the version with an output transformer which offers 'full galvanic isolation between the Pi and the DAC"
I don't know whether its possible to power the SPDIF clock separately but suspect not as the board just plugs into the Pi (HAT) and guess the power can only be provided that way.
I've been told by someone who has one that the SPDIF out is vastly superior to USB. It only cost £23 so worth a go

Thanks to all for your previous insights.
Update: I have now upgraded to a new 282 and a sub for a dramatic improvement in SQ. Congestion is fully relieved, low end extension is much improved and mids are much cleaner, grip/control is explosively better, and there's generally a tremendous ease/air and lack of edge to the music that wasn't as evident before. I'm very pleased.
I have a related follow-up question on my digital conversion that I will post separately in the streaming section. Thanks again.
