Minim stream being throttled on QNAP NAS ?

I'll see if that cures the issue with other playing scenarios.
Sorry for being thick, but what does the 24/48 mean ?

24bit/48KHz is the maximum supported resolution that Sonos supports (CD is 16/44.1). If you want to play a file "greater" than that e.g. 24/192, then you'll need to transcode it to a lower resolution.
In an earlier post you said that you converted an MP3 to "fixed-rate 192 kHz mp3", but I think you meant 192kbps. If the source of all your music is CD and it's stored as FLAC/MP3 then you don't need to worry about transcoding/decoding.

Think of decoding as turning it back to PCM (CD standard), whereas transcoding is converting it from one format to another e.g. FLAC to MP3.
Most players support PCM, so if a renderer doesn't support a format e.g. OGG, the simplest thing to do is decode it to PCM and send that.

I've wondered about putting BubbleUPnP on the NAS, but had assumed it meant that the main 'playing control' route would then have to be via the NAS interface rather than the phone, which wouldn't work - and add more complexity to the setup

There's an additional component called BubbleUPnP Server that can be used to proxy your Sonos speakers so that the playback queue is held on BubbleUPnP Server rather than in the BubbleUPnP app on your phone. The advantage of this is that BubbleUPnP Server can handle multiple queues unlike the BubbleUPnP app so you can control multiple renderers at the same time.

Current process:

Code:

MinimServer -> BubbleUPnP (for browsing) <-> Sonos (for track progress and transition)
MinimServer ->                               Sonos (audio path)

With BubbleUPnP Server

Code:

MinimServer - > BubbleUPnP (for browsing) <-> Sonos Proxy (held in BubbleUPnP Server) <-> Sonos (for track progress and transition)
MinimServer ->                                Sonos (audio path)

The only change you'll need to make in BubbleUPnP (the app) is to play to the proxied Sonos renderer (same name suffixed with '(OpenHome)'), rather than the Sonos renderer itself.
