Some Qobuz 24/96 albums actually 16/96?

We’ve got confirmation from another dCS user.

dCS friends, can you check something for me?

Hi Fred, On my Rossini the same happens. It seems to me these albums are of mixed resolution. If you have more dCS related questions you may want to try the dCS community, at

Seems there are some “mixed format” albums on Qobuz that aren’t labeled as such. Also interesting that Roon’s signal path (and perhaps some software-based DACs) appears to report the label from Qobuz without checking the bitstream.

Anyhow, not complaining, just a curious finding.

If your DAC detects other 24-bit Qobuz albums correctly, perhaps the data stream has some least significant zeroes.

@Fred_von_Lohmann1

The 16 bit tracks all initially display as 24/96, then immediately the display steps down to 16/96.

See zero padding.

Among DACs that report word length, most report full logical word length. Some DACs, though, report only active word length, that is full logical word length minus any LSB zero padding (e.g. 24 bit - 8 bit zero padding = 16 bit).
