Qobuz Lossless Streaming Service Thread

Feb 28, 2025 at 10:09 AM Post #2,191 of 2,199
I recently moved 400 tracks from my library into a playlist and “unfavourited” them so i could start afresh with “library tracks” and i added one track.

That has worked well on my ipad, but on my iPhone it appears that in my library, when i choose “tracks” that one selected song appears but then so do some/all of my downloaded tracks appear below.

How can i stop that? - how do i limit my list of “library” tracks show nothing more than library tracks on my iPhone?

Hello everyone,
since i don't pay to have internet at home, only on my phone, i'd like to know if buying hi-res music on Qobuz, and then transfering the music i bought from phone to computer is totally lossless?
Also, do you know of any other websites that have similar or even better fidelity audio files?

Copying lossless files is 100% exact. It's CRC error checked. What matters is how the files are accessed and the purity of the data stream (in terms of jitter and noise) when you playback the file. E.g. The same exact file played back on Foobar2000 on a gaming PC won't sound the same as the same exact file played back on an iPad and that's because the jitter and noise elements between PC and iPad are significantly different

Other websites are prostudiomasters, nativedsd, hdtracks and bandcamp

Jitter is not, as long as a USB connection is used between the DAC and the source running the UAC 2 protocol, because the DAC clock is controlling the data stream, not the source.

I agree with this, but jitter is never a constant value at all times (disturbances can still happen from time to time due to CPU cycle priority especially when multitasking, even if the DAC is controlling the data stream asynchronously). Also part of it is electrical noise, EMI/RFI (that cannot be measured using FFT of analog outputs of a DAC to the AP555B). Heck why you see people hearing PC noises seeping through USB without galvanic isolation even if the jitter performance is excellent

Very reliable on Windows and iPadOS.
