Sonos not decoding music at full Hi rez - Shame !

Can you hear the difference between 24/48 and 16/44.1 on your Sonos speakers?

Not so.

“Stream high quality audio directly to your Sonos system (up to 24 Bit/48 kHz FLAC)”

It’s certainly true that Sonos doesn’t support higher sampling rates, but the ‘Hi-Res’ 96kHz and 192kHz content on Qobuz -- which typically sounds better because of its careful remastering -- will also be available in 48kHz.

Of course not.  Nobody can.  Anything 48 adds over 44.1 is above 22.05 KHz, where only dogs and bats can hear it. 

Yrs I can unfortunately.  Am a recent convert to Sonos speakers and use it mostly for listening to stuff for flexibility.
 

But I do have specialist high resolution audio gear which to my ears   shows audio quality differences noticeably . 

I also have some professional gear which feeds headphones and, well, it can sound very good indeed. 

Until we understand whether Sonos does sample rate conversion internally and which reconstruction filters it applies all this discussion is a bit academic really. Sonos speakers are great for what they do. 

I recommend you stick to your specialist audio kit for the finer detail.

No, you can’t.  Because if you could, you would be the very first person in the history of the world to hear anything over 22.05 kHz.  

Fair dues .. you are entitled to your opinion .. I have mine .. let’s leave it at that ..  

im not talking about whether I can hear beyond 22kHz which I can’t but you are missing the whole point  about high resolution . I won’t  go into detail about more data of the signal is captured at high resolution..  there are lots of places you can read about it . 

My point is having paid for a service , it’s a shame Sonos feels it needs to limit what their speakers are capable of decoding .. 

I’m sorry, but your opinion is mistaken.  Sure more data is certainly captured, but it is all data above the threshold of hearing.   Trust me, I have read about it, in great detail and even studied the math.  More data does not mean “thinner slices in time”, that is a myth.  Nyquist-Shannon states unequivocally that the only thing which is added by increasing sample rate is to increase frequency response to ½ the rate.  Since 44.1 will exactly sample all data under 22.05 kHz, the only thing increasing the sample rate will do is include frequencies over 22.05 which no person can ever hear.

The fact is, there are no jaggy stairsteps like in the audiophile press.  In fact Sony got sued for advertising that high-res audio is like smaller steps, and were forced to remove their ads.  

Let’s agree to disagree to the hearing aspect .. .. I’m reiterating that  Sonos is short sighted in not letting their newer products work to their full potential due to legacy issues ..
 

If you disagree, tell me where I am wrong.  Tell me how raising the sampling rate gives more data in the audible range.  Show your work.
