What are the Uniti Core benefits over external drive?

Posted by: dave-mac on 13 August 2017

Too play ripped CDs, what benefits would I see if I were to connect a uniti core to an atom, vs connecting an external usb drive? As far as I can see, both sources would use the DAC in the atom?

Thanks for the replies, I was looking at linear power supplies but they all come with the single round plug hence asking.

T.................  Or is that the one you intend to use  !!!!!

I looked a bit more closely,  that is the one you intend to use isn't it ?      The DIN plug is the 12v connection.     The T Power PSU cmpy do supply the correct plug for the Synology which I believe is a 2.5mm coaxial.     But I honestly don't believe it will make any difference,  it's a basic consumer SMPS & maybe the Synology supplied PSU is as good if not better.   If you are going to get a better PSU, then the usual type that most peeps go for is linear (transformer/rectifier/regulator),  but as I said in my previous post,  it didn't do it for me.

similar results with aries mini , changed the original plug top smps  to a to separate smps  with a separate mains lead.  couldn't detect any difference,   then fitted a linear psu to the mini and improvement across frequency range.  good idea to try before you buy..

Mike-B, I have the power supply that came with the Synology, I'm exploring a linear power supply upgrade to it. But the DIN plug is the problem to finding one compatible, I can match volts, amps, watts but not the plug

OK  I see your problem.    My guess is that Synology chose the 4 pin DIN to enable it to connect with a real earth,  their 2.5mm coaxial pluged PSU's (mine) has a grounded (earthed) 0vDC

I'm following the advice here re upgrading power supples the issue I have is how to replace the power supply for my Synlogy DS716+ it has a 4 pin connection  like this. What is the 4 pin plug (in the circle its 10mm in diameter) called and how it is wired?

try to mail to Mr Crespi of uptone audio, perhaps they can build you a special cable with these 4 pin connectors, or also hdplex.  But it is not a standard dc cable of 2.5 or 2,1 mn.  It will not be easy i think.

other solution, for perhaps the same money, would be a melco n1a second hand. Melco produce now the n1a/2, so n1a are on second market. A bigger improvement would be naim ndac used, for around 1000GBP you can find.  Nd5x/ndac should sound better than nd5x/ synology/ linear ps..   But perhaps uptone audio or hdplex can make you this special dc cable...

I wouldn't worry. Just do nothing. Unless you want the megaflange superpower hairybollocks supply from here today gone tomorrow audio.

to be honest with you, adding a linear ps on your nas is not a priority. it is the cherry on the cake. You have an entry level components from naim, a nice system, no problem with that. But if you want to improve your system,  you should begin with upgrading the source:  better dac to your nd5x, or ndx ...or upgrade your amp : nait xs or supernait.  Components first, power cords after, interconnects,  better hifi rack, and at the end linear ps for your nas, better lan cables also.   It is the common progression....just an advice.

I agree with the rooster, better to spend money elsewhere.   Also your NAS with its quad core CPU & other features is not normally found on audio systems,  its more suited to multi access business systems or for home use with 4K TV .  Apart from disk spinup & track access speeds it will not give 'better' audio.

I guess your right, the money goes back in the piggy bank until it can afford to fund the px on a NDX

i think that for the moment your system is not enough resolving to hear a real difference between your nas with smps and your nas with a linear ps.  

With my nds/555 dr , i hear it but it is not night and day between unitserve/ smps and unitserve/linear ps. It is like going from a common power cord to a naim powerline. In a less resolving system, the difference is smaller.

I see you have an nd5x and cd5i: why not sell both and buy an ndx?

you can also see a second hand naim dac, the price of the linear ps , the dac will considerably upgrade your nd5x, a lot more than the linear ps.

 

But you can also upgrade nothing, because your system is well balanced and you can enjoy the music without problem.  Upgrading can become a disease, i have this disease: more we have and more we want to have.

The problem is that when you will have the ndx, you will think after on upgrading your amp and then your speakers, interconnects, power cables, hifi rack, lan cable....

Be prepared for that.

If you are happy with a nas, getting a Core would be pretty pointless, unless you like spending more money to get less flexibility. When I swapped from a UnitiServe to a Synology the sound quality improved. 

Hmmmm, think you might be right ...

My $0.02 worth.

I think the Core connected directly to my NDS (via a Naim DC-1) sounds better than streaming it via UPnP (the route being Core > router > NDS). Note: My music is stored on an internal SSD on the Core.

I have also tried streaming to the NDS via a NAS (Synology) and the direct connection to the Core still sounds better. I used to have a Unitiserve and when compared between the Unitiserve and NAS, the difference (to me) was not perceptible.
