Possible to play 24/192 thru the NDX and SuperNait?

Are you saying you prefer the DAC in the SuperNait, rather than the DAC in the NDX??

If so, what are you using as a 24/192 source?

John

No, I'm saying that if I wanted to play 24/192 files stored on my NAS on a system that comprised the NDX and SN, how might this be accomplished, given that the NDX cannot play 24/192 through its UPnP input?

At the moment you can't, at least not at 24bit 192kHz.  What you can do though is use a program to resample to 24bit 96kHz in order to stream to the NDX. What upnp server are you using?  AFAIK, the NDX architecture  is 24bit 192kHz capable but it will take at least a possible future firmware update to allow it to stream 24bit 192kHz.  I would guess that may be something Naim is working on.  Streaming Hi Res is fraught with possible issues, especailly if you aren't using a wired network.  Even 24bit 96kHz is pretty dodgy via wireless, I'd imagine that 24bit 192kHz is a lot worse.

Anyway, for my 24bit 192kHz and 24bit 176kHz music files I've used dbpoweramp to make 24bit 96khz 24bit 88.2kHz copies, which will stream fine via the NDX as it currently stands.

You can use about any computer with a USB SPDIF interface like the M2Tech Hiface, and play your Hires files with the computer through the NDX digital input... Or preferably talk with your Naim dealer about a trade for a UnitiServe or HDX, and optimaly add a Naim DAC too.

Many thanks Richard. I'm using a simple 1TB Buffalo UPnP hard disk/server as the source. All files are FLAC and the Buffalo is connected via a wired network to my network player which I'm considering replacing with a NDX, hence my question.

I'm sure that a company as far-sighted as Naim will soon solve the issue of streaming 24/192 files through UPnP. When that day comes, would you know if updating existing NDXs involves a simple firmware/software upgrade which can be either downloaded or done locally, or would it require units to be returned to Salisbury?

They are completely different designs. Both can play digital music, but one is a network client and the other is a server. Naim servers have much more system ressources and processing power for data handling, enough for not only their own needs, but also for their connected clients. So it's important to know exactly what you're after to take the best decision.

NaimNet gears put asside, Naim clients are the UnitiQute and NDX, and servers are UnitiServe and HDX.

A UnitiServe will play any files with the help of your Supernait's on-board DAC, you'll only have to set the UnitiServe to resample the high resolution files to address the 96 Khz and 24 bits limitations of the Supernait's DAC.

A HDX will play about any music files you may have, at any resolutions up to 192 Khz and 24 bits. It connects to your Supernait like any other analog source.

Upgrades for both of them would be a Naim DAC. It will significantly lift the audio performances, and would allow the UniiServe to drop the resample feature to play hires files up to 192 Khz and 24 bits.

A good product demo should include other upgrades and optimizations like the XPS power supply, Hi-Line interconnect, Powerline AC cord and Fraim or Fraim Lite audio rack.

Bye.

Thanks again Stoik. It's becoming a bit clearer to me now (I think!)...

SN DAC is 192khz capable I believe

You're right DT79, my memory didn't served me well on this one. So there's no need to do anything but to plug the UnitiServe with a digital coax cable on the Supernait then.

@Singslinger: You're very welcome.

Bye.

PureHiFi, If you have a UnitiServe, I'm wondering why you don't use a nDAC instead of a NDX, and use the NDX in a secondary system somewhere else in the house...

Bye.
