Transcoding NAS

Hi Everyone,

I've tried searching the forums, and whilst there are lots of posts about different models of NAS units, I can't find an answer to my questions.

I have a Unitiqute, and I'm currently streaming from my Mac Mini using Asset UPnP server.  It works really well.  This is the first piece of Naim equipment I've ever owned, and I'm absolutely loving it.  I find I'm hardly watching TV at all now, as I'm listening to so much more music, and buying lots more music too!

That has created a bit of a problem though, in the the hard drive on my Mac is now very nearly full.  I'm ripping to AIFF (just to make life easier in terms of synching my iPhone and retaining metadata) and then transcoding to WAV for delivery to the Unitiqute.

I'd like to move to a NAS system, both to give me more storage and to enable me to use the system without having to switch the computer on.

I'd also like to set that NAS to transcode from AIFF to WAV, but I'm not sure how much memory and processor power this requires.  Is this something that even an entry level NAS could do, or should I be looking for one of the higher-end models.

I like the look of Synology's NAS units, but I'm just looking for some advise about how high up the range I need to go to be able to transcode up to 24-bit/192KHz files from AIFF to WAV without any problems.

I'd be grateful for any advise or guidance the collective wisdom of the Naim Forum can offer.
