Well here are my results: setup: Synology DS212+ running Music Player Daemon Which is connected to the DacMagic Which is connected to NAD c320BEE Which is connected to 2 Monitor Audio BX2's It sounds f*cking awesome. I can control my music with ncmpcpp and MPoD on the iPhone and have streaming options in DS audio from the synology software, and having Ampache running on the NAS to access my library from everywhere over VPN. Squeezebox isn't in the picture anymore, this is just great. Thank you for your reply's, I'm really satisfied with this setup. 44/16 is fine for me, it's what CD's are doing so I'm okay with it.

Allright, My NAS is ordered (synology 212+). But I have to make a decision in the folowing: This review: http://www.stereophile.com/content/cambridge-audio-azur-dacmagic-da-converter-measurements says the USB input has some jitter problems. What would in theory give the best sound quality: Option 1: Connecting the DacMagic with USB directly on the NAS, acting as it's sound card. Option 2: Streaming the music from the NAS over the (wired) network to the Airport Express, which is connected with an optical cable to the DacMagic on one of the optical inputs. I'm aware it won't be any higher than 44,1/16, but the question is will the USB input of the DacMagic cause higher jitter problems than the Airport Express..

rudolffischer, My PS3 is really quiet, it's the slim version which is a lot quieter than the original one. I'm sure the PS3 outputs 24/96 too, but my question is; can the Synology NAS provide the PS3 a 24/96 signal over DLNA?

How about my PS3? Could I get 24bits audio when streaming files from a Synology NAS over DLNA to my PS3 which is connected via S/PDIF to my DacMagic?

But I have never got it to work by connecting a DAC directly to the NAS, even though it has a USB output. I think the USB output is for a printer, thus allowing sharing. Well the NAS products from Synology do support USB audio interfaces, so that won't be a problem. Assuming you are OK with the 16bit/44.1(48) limitation, this could work out favorably for you. The DAC compatibility seems to be hit or miss- someone reported the Arcam rDac did not work when directly connected, so I am not sure what causes some DACs to work and others not to. Well I've read success stories regarding the Synology 211 / 212 NAS'es in combination with the DacMagic, so that's promising. Are you looking to have the NAS located in the same room, right next to your system, or are you looking to have it in another room and stream to the system from there? If the latter, then all you need is a "front end" device to be able to browse and play the music...for example, you can take a laptop computer, set it up to browse the music library on the Synology, then connect it via a USB converter to the DacMagic. Otherwise, you could use a Squeezebox like the others have suggested already. Sounds to me like you just need a "front end" device that takes on the responsibility of accessing your media library that is being hosted by the Synology. Well the main goal is to get a NAS, and connect it to my DacMagic, plus having a decent iPhone app to control the music. I've read good reviews about the DS audio remote app for the iPhone to control the Synology DiskStation audio (http://www.synology.com/us/solutions/mobile/ds_audio.php), since the DacMagic is an upsampling DAC, the sound quality don't have to be that bad with the limit of 16bit audio coming from the Synology NAS, what do you think?

rudolffischer , Thanks, that's a good alternative. The NAS isn't ordered yet, but when its operational I'll try first with the Cambridge Audio DacMagic connected via USB directly on the NAS, acting as a soundcard. I'm questioning myself how big the improvement will be when adding a squeezebox between the Synology Nas and the DacMagic according to my setup, compared to the situation without a squeezebox. My setup contains: DacMagic NAD C320BEE Monitor Audio BX2 speakers. What do you think rudolffischer ?

I'm aware of that. But my question is, can a USB SPDIF converter output 24bit from a Synology Nas? My DacMagic supports 192/24bit with no problems on the optical port, but that's the situation on the other side of the USB converter.

And what about a USB to optical adapter, plugged into the Synology Nas? Will that be a solution to get 24bit audio output or is USB the bottleneck in this case?

Hi All, My question is regarding my DacMagic. Is it possible to output high quality 24bit audio (like Flac files) from this DacMagic when it's connected via USB on a Synology Nas? (IE the DS212) Or do I really need a device like a cambridge audio NP30 to realize this?
