New Uniti Core

Posted by: No quarter on 12 July 2017

i got word from my dealer that my Core has arrived,I will be picking it up today,and hopefully playing music from it shortly after.I have not bought I hard drive yet,so my plan is to plug a 64 Gig thumb drive into the front,connect the SPDIF out to my N272,turn on the app,and begin set up.I have read over the tutorial at the top of this forum,and it seems pretty straightforward for what I want to do initially.Does anyone have any advice for me,as to what watch out for,what not to do etc.?I will start looking for hard drives this weekend,but I am hoping to at least have it playing something later today.I have no NAS,so this is replacing all my music that currently sits on a western digital hard drive,plugged into my laptop.I have been using J-river to stream from the laptop.Eventually I will rip all my cd's,and want to transfer the music from the 2 TB hard drive to the Core.Thanks for any advice in advance.

I think youll find that is correct.

Yes as PCD says that is right - Samsung changed the labelling on the box so the description Naim gives in the support info is out of date. Had me wondering for a while too when I bought mine. The caddy only picks up on three holes, so ignore the fact their are four on the SSD.

I managed to get the SSD drive installed,formatted,and I am now ripping all my CD's.I have about 20 done so far,and I am listening to Rush 2112 wav rip,sounds fantastic.My next question is,should I transfer my music from my WD external hard drive to the SSD drive in the Core,or just plug it in the back of the unit,and leave the SSD for "new music",after all my CD's are ripped?I only have about 150 CD's,so they should not take up too much of the 1 TB SSD.I believe I would have to set the external drive as a share folder.I also noticed I can now see the Core on my laptop in the other room,can I transfer music to the Core on my laptop,I mean,add music to the existing drives from there(ssd and external)?Next,if I want to switch to outputting from the digital out of the Core instead of UPNP, how do I do that?

i would transfer all at the end of ripping on the ssd drive and keep the hard external drive for back up.....a lot do that. enjoy

Glad it's all working for you.

re your WD drive, you can do either. It's up to you. There shouldn't be any difference sound quality wise, so it's just about convenience etc. Yes you set the WD drive as a share and then the Core will scan it and include the music in its menus etc.

if you are ripping in WAV it's probably about 500 MB per album or thereabouts. FLAC is about half that. These are gross generalisations but for the purposes of a quick calculation will do.

Yes you can move music into the "Downloads" folder in your SSD from a laptop across your network. This is what most of us would do. I don't know about adding to the WD drive across the network, but if you can see it then the answer is yes. You mustn't add anything into the "Music" folders on the Core because Naim say that risks breaking the indexing and potentially you would have to start again.

To output by spdif rather than upnp you just connect a suitable digital lead between the Core and your 272, select that digital input in your 272 instead of upnp (using the app or the remote) and then you go into the Core in the app and select your music and play it from there instead of from inside upnp in your streamer.

This isn't really a problem with an SSD drive! I'm sure that if Naim thought it needed four screws they would have accommodated that.

On the Core if you go into Manage Music then Configure music stores then View store then advanced info it will give you all the information about your internal hard drive which include  capacity and what is available.

I have a 2TB  internal hard drive and ripped about 600 CDs in WAV  it shows I have 1.6TB left..

Thanks for the replies guys,you all have been very helpful,especially David.I am really liking the natural full sound I am getting now,last night I switched from using my Dynaudio XD 600's via digital input from the 272,to the 250 DR feeding my Dynaudio excite 12's.This combo is "all Naim",and I must say,just loving what I am hearing,I wanted to get the 250 DR warmed up properly in anticipation of the arrival of my Dynaudio special 40's that should be here next week.I have been taking a walk down memory lane if you will while ripping my CD's,a lot of them I bought in the 80's,and have not played for many years,so I a even enjoying the process of ripping to the hard drive.Each CD is only taking a few minutes to rip,and I have not had any issues so far with the wrong Metadata or anything...so I am very happy that I chose the Core over getting a traditional NAS,so far.

David , as a SSD has no moving parts and a standard hard drive has bits whizzing around at high speed this could explain the different fixing methods.

Err yes. That's exactly what I was saying too!

I got all my CD's ripped to the hard drive,which is only 131 albums,most of my music is on an external hard drive,I have about 1.2 TB on it.To set it up right,do I power down,plug it into the USB in the back,power up,then go to manage music>configure music shares,or configure music stores?Another question,my Naim app is still the old version,I think it is 5.6...should I hold off on updating the app?

Posted on: 20 July 2017 by David Hendon

You shouldn't need to power down. Plug it into the USB, leave it for a minute or so and it should be there in the app so you can set it as a share. Once you have done that the Core should start to scan and index it. If you watch the albums page in the Naim app you should see it update every 20 albums or so.

i would stay with 5.6 if I were you.....5.7.1 is basically for the Atom and is buggy for other devices still.

I think I might of transferred all my music off my external drive onto my SSD drive by accident.i wanted to set up a shared folder,but there seemed to be no option for that,so I tried  configure music store,then it asked me where to import the music from.This was just before I left for work yesterday,when I got home,it said I have 1400 or so albums,which sounds about right.At that point,I was not sure what to do next,like hit something to end the import,or what.My problem is,I am not very familiar with the unit yet,so it is kind of a guessing game as to what I am doing,or have done.If I unplug the external drive now,is there a risk of losing it's contents? How do I know if i am now playing all these albums off the SSD or the external drive? I did notice today that a few of the albums I tried playing,stop all of a sudden,so what would happen if I tried to import more music than The SSD had space to hold?would I get partial albums,would it just stop on it's own when Full?...confused for sure.

It should all be fine, but you might want to think about using upnp to get your music onto your 272 rather than spdif. Your Core and 272 will be connected to your network anyway.

There is some debate about whether upnp or spdif from the Core sounds better, but into a 272, I would suggest starting with upnp. It costs nothing to try and you can change/compare it later if you want to.

if you are going to rip CDs then you probably will want an internal hard disc quite soon because a 64 Gb USB drive won't hold many albums. The recommended hard disc doesn't cost much and you can buy from any number of sources via Amazon or whoever.

Good luck!

I have had both the 272 and the Core for quite I bit of time. I bought the 272 around it's launch and the core when it launched. I can tell you the S/PDIF into the 272 sounds better - and not just in my opinion - many on this forum and my dealer have said the same. I encourage you to A/B it is very very easy to do, but I believe you will find there is no reason not to use the S/PDIF and the excellent DAC in the 272.

Posted on: 21 July 2017 by No quarter

Thanks DUPREE,I do plan on trying the SPDIF this weekend,I wanted to get all my music loaded up first.I also have a Hugo 2 on its way,so I plan on feeding the Hugo from SPDIF also,to the analog in on my 272, but expect I tight race,the 272 DAC is no slouch.

Sorry I wasn't around to help when you posted this.

Configure music shares is the top option in "Manage music" in settings, just above "Configure music stores"

it depends what you defined as a store. And I assume you didn't accept the option to format the store? You probably have imported all or most of your albums into your SSD. It may have completed now.  If I were you, I would put the Core into deep sleep and once it's done that (no longer visible in the app), pull out the USB disc.  You shouldn't lose anything as even if it is still importing, it should finish or abandon that file and terminate the import before shutting down. In any case it shouldn't affect the USB drive as the Core will only be reading that.  (For future reference you can always restart an import. The Core works out where it got to by looking at filenames and carries on from there.)

Then you can restart the Core and see what is going on. You will have to wait a few minutes while it rescans and tells you what it has found. You can also look at the SSD folders on a PC and see what is in them. All of the imports, unless the RIPs originally came from a Naim server, will be in the Downloads folder. If you want to back out of what you have done inadvertently then deleting the imported albums with a PC is the easy way to do it. You mustn't delete or alter anything in the Music folders though as this can break the Core's indexing and you might have to do the ripping of CDs all over again from scratch.

If the SSD is full then all that happens is that a) the import will fail and stop when it can't fit the next track in (it imports track by track).and b) you won't be able to rip any more CDs because there is nowhere to store them.

Anyway tell us what you find and we can all have a think about what to do....

 No Quarter, indeed  the 272 uses the well regarded Texas Instruments PCM 1792a DAC. TI have developed a technique they call 'advanced segmentation' which apparently offers strong dynamic range performance at low distortion at a more affordable/consistent manner than the older ladder architecture of the PCM 1704. Although the 1792a has an inbuilt FIR implementation, I believe Naim disable it and let that reconstruction filter function be handled by, in the case of a N-272, a third generation ADSP 21369 (SHARC) DSP controller.

Of course the final performance is very much down to the implementation and this is where we enjoy the benefits of the Naim design so we can hear what these devices are more  truly capable of. There is little point in using high quality components if you are masking much of their  performance through mediocre implementation. However there will be a characteristic sound that I suspect many/some will notice between a Texas Instruments 1792a compared to a Texas Instruments 1704k (and compared to a Chord Electronics Pulse Array DAC) that will become noticeable in better implantation such as with Naim due to the different DAC chip architectures.

Simon,always good information from you,thanks a lot...once the Hugo 2 arrives(hopefully soon),I am going to compare it to the 272 DAC,it should be interesting to see which I prefer.I did a similar comparison when I first got the 272,but with the Hugo 1,and I decided to go with the internal DAC of the 272.I kept the Hugo for headphone use,but have recently sold it to a friend,in anticipation of the 2.When I did my original comparison though,I used my UQ 2 as a source into the Hugo,and I did not have the XPSDR on the 272.I would imagine the Core is a better source than the UQ 2.Good times ahead for me,in this wonderful hobby.

David,I put the Core into deep sleep as you suggested,removed the external hard drive.There are now 983 albums on the Core,which is down from the 1486 albums I had with the external drive connected.This tells me that 983 is all that would fit on the SSD,and I confirmed that the 983 albums are visible on my PC,under the Core.So other than the fact that my SSD is now completely full,everything appears to be ok,I even plugged my external drive into the PC to make sure all the music is still there,and it IS still there.Thanks for the help again,I am sure I will need it again soon enough,now I plan on trying the SPDIF output today,as DUPREE suggested,I am hoping to hear an improvement over UPNP.To operate in this mode,I believe I have to activate a digital input on the 272,under tools,and then pull the music off the Core using the 272 in the app.

Glad everything is ok, but I thought it would be. What you could do is delete the albums from the Core that you didn't mean to import, plug your USB HDD in again and this time define it as a share, in which case the Core will scan it and offer you all the music through the Naim app. You won't notice any difference wherever they are stored - it's a feature of the Core that you can store your music in multiple ways.

When you use the Core as a hard drive directly connected to the 272 using spdif, yes you need a digital input on the 272 to be turned on which you do in the 272 setup in the App or using the 272 remote control. I think they are on by default though so unless you have previously turned them off, it should just work.

The main difference in operating is that rather than going into upnp in the 272 bit of the app and selecting/controlling your music there, you instead do it in the Core part of the app, having first selected the 272 digital input of course.

I got it to work in SPDIF... for about half a song,then it pauses for a second,plays again,then stops completely,and a window comes up on the app that says "streamer not responding".

Not sure what is going on,I tried a couple of different digital inputs,2 different cables,same thing happens.One thing I did notice,on the Core,the power button flashes for a few seconds every 5 minutes or so,then goes back to solid light....help!I have some other things to do today,so I will try it again later.

I think what is happening is that your Core is going to network sleep. It does that automatically and it doesn't matter for upnp, but it probably does for spdif.

You can adjust the auto sleep timing in the Core setup in the app. If you set it to something long, like two hours or never then you should be ok. But I am guessing a bit here because I never used my Core in spdif mode. The difference in power consumption between On and network sleep is trivial and with an SSD your Core won't get hot even if it's fully on permanently.
