reply hash30. Was aware it only goes to that resolution with Sonos, but with my streamer into very good dacs, speakers and amps, is that playing hi-res its only slightly different to CD streamed quality, not often better than CD streamed stuff, as its so much recording dependent anyway and the DR ability of the track. You can discern hi-res and Cd quality streamed stuff quite easilly, but again its not huge on good recorded stuff. I admit it may be more marked in better systems to mine, but for systems like this play 3/5 speaker its pretty much academic. I wouldnt trust anyone that says that they can discern hi res and CD streamed stuff on budget hi-fi as being very marked, as it will be just hyped up stuff for the sake of the fact they own a hi-res capable streamer and have paid the cash for it., so dont want to deride it. Im happy to deride stuff even if I have paid for it and found its not as good as I first thought.
Part of the issue with sonos and the Connect's is its reputed to be jittery and this can make all the difference I think in what sounds good compared to other streamers, whether they are hi-res or not. But its a question of balance as if you are pairing a connect with a sub £5000 hi-fi its going to be perfectly OK, but start spending more you are going to hear the difference to better streamers.
