Qobuz vs idagio vs primaphonic


What is the best streaming service for classical music in terms of content, quality and reliability ? 
I have Aurender and node for streaming. Currently have tidal which works well but content seems lacking.

Yeah! Thanks guys. I just did a quick cruise of Qobuz and Primephonic and it seems they do have a selection of complete operas. I didn't actually play one so I'm not completely confident they do deliver the unexpurgated goods.  But thanks for turning my head around.
@melm: I signed up for prime phonic and listening to 24/96, so it says. How does one verify if this is indeed the rate? 

Does anyone know if Aurender supports idagio or primephonic ? 

I have an Aurender a100 with a build in MAQ dac, and it does sound superior to my ears. I have yet to try DSD files. 

Is airplay lossless via bluetooth connection from my iPhone to aurender ? 

Is airplay lossless via bluetooth connection from my iPhone to aurender ?
Airplay streams over WiFi (not Bluetooth), at 16-bit/44.1kHz lossless. If the audio source has a different resolution, it will be resampled to 16/44.1 before transmission.
@ei001h,

To tell exactly what you have, you have to run some of the track through a diagnostic program.  I use MusicScope, unfortunately no longer available.  I do not know of a similar program.

Primephonic does not tell you what the sample frequency or bit depth of any of their files is.  In fact they give very little information to anyone.  Neither The Absolute Sound review or the PC mag review says what their maxmum sample frequency is.  I find that remarkably deficient for a serious audio review.  They only say that some of their tracks are at 24 bits.

When I tried Primephonic, I ran a lot of track segments through MusicScope.  I identified only 44.1 and 48kHz as sample frequencies given the maximum audio frequencies received.  Of course I did not run them all, but I would be astonished if there are any higher than 48kHz, given the number I ran.
melm -- thanks for the data on Primephonic, but in the end I'm just a subjective guy.  Though not always, I can count on Primephonic giving me lovely sound via my Mytek Brooklyn and Primaluna. Not quite Qobuz, but in the main it's the fidelity of the source material that rules the day.
