When a 192/24 FLAC download becomes a 160k/MP3

What device are you using to stream them to the NAC?  If it's a uPnP server is it setup to transcode to MP3?  If you have a direct digital connection from a PC / Mac is the player software doing some similar transcoding?

Thanks Nudger, well spotted - but like many IT issues it's an onion question...Yes, you were right in that I was looking through my MediaMonkey library, and the UPnP options hadn't been set correctly, so MP3 was being streamed.

But....the reason I was using MediaMonkey was that I couldn't see those albums directly on my media server after I had transferred them, from my PC where I had downloaded them to. Normally I look directly at the media server (a Netgear as it happens) from the 172. I still can't see them if I look directly, but if I look at the location, through MediaMonkey, I do see them and they stream as FLAC. Yes - they are in my system twice at the moment - once on my PC, and once on the media server.

All in all I'm probably better off looking through Media Monkey as I have more control of my library from there, but it's still nagging me why I can't see them looking directly.

Needless to say I'm also playing with the new Android app at the same time, which is probably adding to the confusion, although first signs are very encouraging!

Rescanning is my first stop when an album doesn't appear as expected, which I normally ensure by powering off the 172 and then powering on again, but I've tried that a few times and they haven't appeared.

Needless to say a chain of events has now occurred! Looking at the MediaMonkey Library from UpnP on the 172 works fine from the remote, but when I look from the new Android app Media Monkey doesn't appear, only my mediaserver. I do have MediaMonkey Pro installed on my Android, but haven't explored any interaction with the Naim app.

Hi PhilipH, got quite a few Albums from HighResAudio.com – never ever had any issues with their FLACs being MP3s. I would (like nudger wrote) suggest to check that no transcoding is activated on your UPNP server.

Hotel California from The Eagles is right on my playlist – please find a screenshot from the Naim app for reference what it looks like when I play that FLAC thru QNAP-HS210/Twonky/NAC-N172XS

Hi

You don't rescan the drive by rebooting the 172, you need to rescan your UPnP server.

Assuming you have a Readynas drive, you have a DNLA server built in. Login to the server using radar, and switch the DNLA setting off, then back on again after a minute or so. This will rescan the drive, and the new tracks should show up.

There is no need to use Mediamonkey, unless you want/need music from your PC. The DNLA on the NAS is all you need, and that should not transcode to MP3.

Also, a better server to install on a Readynas is Minim. Google Minimserve and follow the instructions. This can also be set to convert FLAC to WAV on the fly, which you MAY prefer the sound of.
