Naim Uniti Core, HiFiBerry Digi+ Pro, Allo DigiOne and SPDIF DACs

Naim Uniti Core, HiFiBerry Digi+ Pro (Raspberry Pi HAT) and Allo DigiOne (Raspberry Pi HAT) are relatively new devices. 

They all can provide a direct, high quality SPDIF feed to a Naim DAC. This thread is meant to discuss their advantages and disadvantages as SPDIF sources for SPDIF DACs. The idea is to focus on differences in sound quality, reliability, flexibility and usability, not on price differences.

Original Post

I cannot comment on the HiFiBery, but I've ordered the Allo DigiOne Player which includes a RPi, a DigiOne board, a case, and very important, a low noise power supply.

I do already have the iFi 5v PS, which costs these days 60 Euro. the Allo PS can be bought for 25% of that money.

No nDac here either. I'd love to have one, but it seems to excel mainly when a super duper expensive PS is attached to that. Since my Pre-amp is not even on a proper level, I need to reserve money for that first.

Thanks for posting your finding! I have a bare Naim DAC that I have bought second hand. I think that the last firmware upgrade (Dec. 2015, if I am not mistaken) has made the Naim DAC without a 555 PS quite attractive. There are of course a number of very competent alternatives to the Naim DAC of course. Best, nbpf

The DigiOne has arrived, an sd card was setup having a fresh Raspbian installation. VNC installed, all configurations done (thanks for mentioning dtoverlay=allo-digione, nbpf) MDP was installed. But ... I forgot to get a proper coax cable ...

Any recommendation for a coax to coax cable? Normally I get the AudioQuest cables, but if there is something significantly better, I'd be interested.

I am using the same Naim DC1 that usually connects the M2Tech HiFace Evo to the Naim DAC. I have not looked into SPDIF cables recently. Before I bought the DC1 (about two years ago) I had a Mark Grant cable which seemed very good to me. Best, nbpf

I have managed to install bubleupnp on my macbook following set up instructions using terminal on mac.  If you google  'how to stream Tidal via Raspberry Pi'  an excellent guide from HIFIZINE will walk you through it all. 

I have found that occasionally  I have to restart server on the Networks tab of bubbleupnp if I haven't been using it for a while which isn't ideal of course so any help on that would be good.

I have been using the Lumin app to control Volumio from my iphone but again it isn't ideal I will try LINKSY as I've tried it on my mac and it is ok.

My next step is to run the Pi in headless mode so I do not have to have it connected to the mac and I can use the Pi's own psu for this I need an ethernet to usb adapter apparently?

I have to say that using a Pi for me is a compromise as I traded in my Naim streamer for a better Nap but I have to say so far SQ wise I'm perfectly happy and this is without a better power supply for the Pi but key to this I believe is buying best dac you can afford.

The one thing that I am finding difficult is controlling the Pi as a streamer in a way that comes close to my experience with my Naim streamer which was pretty slick and trouble free.

Which PI do you have? I have the RPi 3, and they have several usb ports and also an ethernet port. I have various powersupplies hanging around, the IFI 5v powersupply is one, but also the Allo PS which came with my Allo Digione Streamer. Both the iFi and Allo ones are good. You can perfectly use a random phone charger, but this might cause hums / noise. A powerbank will work also nicely for a few hours.

I only use Pi's headless. The trick is to load an image on an SD card of e.g. Raspbian, and then put a file 'ssh' in the root. No fileextension. This will allow the Pi to be connected by SSH. I do have an unix background (did Oracle installs for a few years), so I have a headstart there. This could be different for the most people.

I'm not using Tidal, but Spotify. Raspotify works seamless, and I can also use volume control from my phone. Trick is to set

    mixer_type     "software" instead of

    mixer_type     "hardware"

in the file mpd.conf. Raspotify is a package to be installed on the RPi which allows the normal Spotify client to stream to is using all functions. There is a tutorial on the Spotify site.

Next to Raspotify, I use HIFI Cast to stream my music which is stored on my Synology Nas using Minimserver. This is also a flawless and seamless integration. No issues, no restarts. Just perfect.

All I miss now is to use the Naim volume control. It is digital currently on the Streamer.

When I have a decent Dac, I'll set the streamer  / dac to fixed output and will use my Naits remote control.

You are totally right on your observation that SQ is good but convenience might be a step back. Its a bit finding your own way. In my case, I like it. I'm thinking on writing software myself to control all the digital devices.

Have you tried Roon? Admittedly it needs a Mac/PC or dedicated hardware but for streamer control it is 10x more convenient than any app I have tried, including Naim, Lumin, Kinski, etc.

I now have a spare DigiOne because I am getting better results with Allo‘s USBridge via a cheap USB cable into my DAC. Plus I don’t have to worry about which S/PDIF cable to buy.

I am powering the USBridge and Sparky (its Rpi equivalent) separately with a pair of iFi iPower supplies. Very clean, very low noise floor.

You are absolutely right, the DAC is the key to SQ. The key to convenience in my setup is Roon.

I do not know your setup and what you are trying to do but I guess you mean BubbleUPnP Server, not the Android BubbleUPnP control point and renderer app. What do you need BubbleUPnP Server for? I have one instance of BubbleUPnP Server running on a RPi wired to my router, but this is only to turn a Chromecast Audio in the kitchen into an OpenHome renderer. Both the wired RPi and the BubbleUPnP instance have been up and running since a few months, no need to restart BubbleUPnP Server here but I hardly use it anyway.

Linn Kinsky has been discontinued. As an alternative to the Lumin app, you can try Linn Kazoo or BubbleUPnP. The latter is only available for Android, I believe.

I do not know how you use the RPi but I am actually quite happy with BubbleUPnP (Android) and Linn Kazoo (Android and iOS) as control points. I never tried the Naim app in my environment, only at my Naim dealer. What I  very much like of BubbleUPnP (Android) is the capability of opening the booklet of the currently playing album using the metadata made avialable by MinimServer.

I should perhaps point out that I am using a RPi with an Allo DigiOne hat as an integrated UPnP server and renderer: my music files are stored on a HDD connected to the RPi via USB. On the RPi I am running both MinimServer (a UPnP server) and upmpdcli (a UPnP renderer). The DigiOne is connected via BNC to a Naim DAC. Thus there is no data transfer over my LAN at replay time (apart from the controls sent to the renderer by the control point) and the control point is extremely fast and responsive. The RPi is connected to my LAN via wireless, no need for a wired connection of course.

Thanks. I found a cable which I used to connect my TV to my AV2. Using that for now. Will replace it later, when I have a better Dac.

I have actually never used an RPi in any other mode than headless and I have deselected HDMi output (adding "sudo /opt/vc/bin/tvservice --off" to /etc/rc.local) and audio from the RPi internal audio card and bluetooth (add "dtparam=audio=off" and "dtoverlay=pi3-disable-bt" to /bbot/config.txt). You can find further suggestions for fine-tuning an RPi for audio playback if you google "archimago CRAAP". I do not fully understand what you want to do with the RPi, thus it is hard to say what you actually need.

Makes sense, just make sure that it is a 75Ohm cable.

I had a fresh install of Raspbian on my RPi. Raspotify worked, MPD worked. I was able to use the DigiOne.

I could not get upmpdcli to work, and therefore streaming my hi-res files from the NAS in a convenient way was quite problematic.

During the install of upmpdcli, it was complaining about non installable libaries. The issue was that I had the latest version of Raspbian: stretch. I flashed the sd card again with a recent version of Raspbian Jessie and all was up and running in an hour or so.

This is a bit strange, I have installed upmpdcli on Raspbian stretch with no issues. In /etc/apt/sources.list.d I have two files:

raspi.list

upmpdcli.list

+ the search for a Dac should start soon.

Great! I am very happy with my second hand Naim DAC. At the moment, I have 4 sources connected to it: one optical (a TV) and three electrical (blu-ray player, DigiOne and M2Tech HiFace Evo). There are many very good DACs out there but the old nDAC is hard to beat when it comes to connectivity! Have fun with your search. Best, nbpf

Hi nbpf

I'm a total newbie to the world of RPi and have no clue at what I'm doing how I've managed to get any noise from it is a mystery so please forgive my ignorance and any help would be greatfully recieved as my partner is very unhappy that she can no longer open an app on her phone and play music. So please help and extract me from the doghouse what I wish to achieve is to use my Pi as a standalone streamer that I can control via an iPhone/iPad app without having to have it connected to my laptop ethernet wired connection to my BT hub is fine.

What you have written above is double dutch to me nbpf when I had to upload bubbleupnp to my macbook I didn't even know what terminal was and had to look it up!

I like the nDac too, there are some pros and some cons - as usual for any product.

Pro:

It is Naim, therefore likely to adhere to the company philosophy and vision (strange word here, 'vision') on sound.

It has Din connectors. I'm a huge fan of this because it takes care of many things. I got to understand the importance of this when I tried to integrate a Turntable in my setup.

It has many ports for Dac standards.

It is solid, my Kids won't break it.

It has a very decent price if bought second hand.

Cons:

It is another serious box. Since it is going to be part of my Active setup, I have already quite some boxes.

I will be tempted all the time to add a super expensive 555PS power supply.

@Bob: How are you getting on? Have you tried Linn Kazoo yet as a control point? You should get reasonable results using that and Bubbleunp. The instructions you found on Hifizine are very comprehensive.

On the other hand, if you have a birthday coming up, you could spoil yourself with a dedicated music server, which would allow you to switch off your MacBook. I recently took the plunge with a sonicTransporter from Small Green Computer company. Mine has an internal disk but with the base model you just need to plug in an external hard drive containing your music files. With that and your Rpi (suitably configured) on the same network you no longer need your MacBook to be connected. It ships with a 60-day Roon license which is your get-out-of-doghouse-free card with a slick app and integrated TIDAL streaming.

P.S. You can find lots of useful info and help on Rpi streaming at the Roon Community site by entering beginners in the search box.

Good suggestion from William.

It the sonicTransporter is too expensive, you can also buy a ChromeCast Audio + spdif optical cable an run this into your Dac.

Spotify and Tidal supports that and it will be a massive increase in convenience, and a slight decrease in SQ.

However I don't know your wife, I think she will be happy again.

The DAC V1 also has an SPDIF input. And there are some other DACs with SPDIF inputs notably the Chord range, that many who have compared with the Naim DACs prefer (my assessment being a greater 'naturalness' of the sound, others describing as more organic or analog-like). The lower priced Chords have less choice of inputs than the n-DAC, though that is only significant if you have multiple digital sources.

One thing of which to be wary is that different DACs can vary in their sensitivity to both jitter and RF in the rendered digital stream (e,g unlike their more senior siblings, Mojo and Hugo are particularly sensitive to RF, which has an adverse effect on sound quality, though not so much to jitter because they reclock). This will have a bearing on the sound quality of the source-DAC combination, so as part of the discussion, as well as learning what people may have done to address these causes of degradation especially in respect of the non-hifi-box souces, it will be interesting to learn how the different sources compare into a range of different DACs, though I suspect few will have been in a position to do that

I still do not full yunderstand how you want to deploy your RPi. Do you have a DAC with SPDIF inputs? Electrical? optical? both? Do you have a USB DAC? How is your RPi connected to your DAC? What OS have you installed or want to install on the RPi? Raspbian, Volumio, DietPi or others? I cannot provide detailed installation and setup instruction in this forum but if I understand what you want to do precisely I migh be able to point you to pertinent resources. There are very good and detailed tutorials for virtually every task. If you have a UPnP server in your LAN and you want to use the RPi as a LAN to USB bridge for a USB DAC, all you need to do is to install upmpdcli. The upmpdcli web site contains detailed installations and setup instructions. This will also give you access to Tidal, Qobuz and GoogleMusic. Please, see also the very good recommendations by  William and Ardbeg10y above!

@Ardbeg10y: have you mangaged to install upmpdcli under Raspbian stretch? I have tried to post the repositories that needs to be included by sources.list (the content of the files raspi.list and upmpdcli.list mentioned above) but my post was moderated. I guess that we are not allowed to post names of repositories in this forum, I'll have to double check. Anyway, the upmpdcli repositories for Raspbian stretch are listed on the upmpdcli web page in the downloads section and the installation worked flawlessly for me. Best, nbpf

In this case you should probably better look elsewhere. For me, I have decided that I do not want expensive and, above all, large PSUs. Neither for the nDAC nor for the SN2. A second hand nDAC is a very good value for me. But if I had to upgrade, I would first consider more modern designs rather than adding a PSU. I have been considering buying a second nDAC as a backup, however. Second hand, od course. Let us know what the search for a DAC yields in the end!

It is currently running Jessie and I'm happy with it. MPD, upmpdcli and Raspotify work.

Stretch should work too, but I've not tried to move further. Maybe I buy another sd card to try. Looking backwards, I think that I've taken a wrong installation sequence. I first made Raspotify to work and then MPD + the failed attempt for upmpdcli.

Now, on Jessie, I installed MPD first, the upmpdcli and as last step the Raspotify.

I'm a bit busy for my work so cannot spend too much time on it. I've decided to quit my current assignment so at the end of the month I will have time. Will try to get my unix knowledge back up to speed by these RPi's. I've built webservices in the past so lets see if I can get that running nicely. Would be cool: a loadbalanced cluster of application servers on RPi's.

Another idea I have is to make a night movie of all the creatures in my quite large garden. I recently catched the warthog on photo and a RPI + night cam would be cool.

I think that gardening and installing / setting up software have much in common. Anyway, one of the nice features of the Raspberry Pi's system is that one can easily backup images of the SD card. I have a number of RPis and I regularly make copies of their SD cards on my backup drives. Best, nbpf

If one wants to use the Allo DigiOne with Raspbian, one has to add a line with "dtoverlay=allo-digione" to /boot/config.txt  for the system to detect and configure the Allo DigiOne card at boot time.

If you are using a so-called audiophile distribution, it is likely that support for the DigiOne is already enabled in your config.txt. Here are my current additions to the file:

# Disable internal (snd_bcm2835) audio
dtparam=audio=off

# Configure the Allo Digione audio card
dtoverlay=i2s-mmap
dtoverlay=allo-digione

# Disable bluetooth
dtoverlay=pi3-disable-bt

# Archimago CRAAP settings
# arm_freq=800
# sdram_freq=400
# core_freq=400
# gpu_freq=300
# over_voltage=-4
# over_voltage_sdram=-4
# gpu_mem=16

Best, nbpf

I've been running piCorePlayer on a DigiOne without any issues. Easy setup and I can control LMS from my PC, smartphone or a synced SB Touch's screen via remote control. Using the same 5V linear PSU that I was using with my Touch sound quality is better on all levels compared to the Touch and to an sMS-200 (with stock SMPS) which I previously owned. If I were to upgrade I might look towards an sMS-200 Ultra with sPS-500 PSU but that would cost 10x what I paid for the DigiOne.

Interesting device the sMS-200 Ultra but no SPDIF output, I am afraid! At the moment there seems to be no alternative to Naim Uniti Core, HiFiBerry Digi+ Pro and Allo DigiOne where an electrical SPDIF output is needed. A Schiit Eitr or a Mutec MC-3+ Smart Clock USB are certainly valid propositions but add to a player/renderer an additional box. Best, nbpf 

For me S/PDIF was imperative as I no longer own a DAC with decent USB input. In all fairness the sMS-200 might not have been given a fair shake as, in addition to being used with its SMPS, it was feeding the diminutive Chord Mojo whereas the DigiOne is using a linear PSU and its S/PDIF output is being sent to less compromised full sized DAC. As good as the Mojo is it does have its shortcomings.

I have meanwhile compared the RPi + Allo DigiOne (with ifi PSU and music library on attached USB HDD) to my current source (fitPC3 + M2Tech HiFace Evo, both powered by TP PSUs, also with music library on attached USB HDD) into the Naim DAC.

Both the RPi + Allo DigiOne and the fitPC3 + M2Tech HiFace Evo were running MinimServer and the upmpdcli UPnP renderer with similar settings. Upmpdcli relies on MPD which also was running essentially under the same settings on RPi and fitPC3.

I have not done truly systematic comparisons: I have first listened to the RPi + Allo DigiOne for about two weeks and than compared two short pieces of music that I know rather well.

My impression is that the RPi + Allo DigiOne is almost as good as my current source but perhaps not quite there. The soundstage is perhaps a bit better but the violins sound slightly more aggressive. I have the impression that the faintest and more delicate sequences (the first seconds of Sibelius violin concert, for instance) are slightly better rendered by my current system. The differences are certainly not big and perhaps quite subjective.

From the point of view of functionality and simplicity, the RPi + Allo DigiOne are clearly hard to beat, the two systems are comparably flexible and reliable. I never had to restart the RPi during the two weeks of testing and the fitPC3 has been running for months since the last reboot.

Thanks for posting, nbpf.

I assume you have tested this on your Ovators. I have been impressed by the amount of details Ovators can show. Since I have Ovators, it has been so easy to distinct good and bad recordings. BMR's are fantastic.

Regarding the RPi - I share the observation that RPi's are rock solid. Never needed to reboot. Once the run, they run forever. This also gives me a bit the feeling that I should not touch them in order not to break anything. Maybe I should just get more sd cards and copy in order to start tweaking.

Yes, I have listened to the two sources wit the Ovators. I agree the BMR are fantastic. I have demoed a number of speakers and to me the Ovators just sounded "right" from the very beginning. I like to listen to music while laying on the sofa, sitting at the table or in front of the fireplace and in all settings the Ovators sound right. 

I should have probably compared RPi + Allo DigiOne to my current source also on headphones. I have very revealng ones but I feel that the headphones output of the SN2 is not so great. Perhaps I'll do another round of comparisons on headphones.

I keep images of the SD cards of my Raspberry Pi devices on my laptop and backup disks. If something goes wrong, I can always copy the image to a SD card in minutes. To this end, it is useful not to have too big SD cards. I usually buy 16GB ones.

While OK for TV/movies the headphone out on all Naits is mediocre at best for music. I would never use it to evaluate any upstream components.

Good to know, thanks Iconoclast! Any suggestions for a good headphone amplifier for a Sennheiser HD800? Best, nbpf

Having a bit of a frustrating time at the moment trying to get Pi recognised by my mac for remote use I have downloaded Jessie Lite loaded it on to my sd and inserted into my Pi then I have found my Pi IP address and then opened Terminal on my mac and typed ssh Pi@ - IP address  Password: Raspberry and then I get a message that connection cannot be made and something about Port 22???

ssh is not enabled by default on most unix distributions. you need to put a file 'ssh' in the root of the filesystem.

so, take the sd card, put it in the pc or sd card reader and create a file 'ssh' (no extention nor contents) in the root, put the card back to the rpi and there you go.
