Is it weird that my dac showed 23/352 instead of 24/352?


Recommended Posts

I have the Polarity album for sometime and I have not noticed previously that my ladder DAC showed in the display that it is 23 bits 352Khz instead of 24 bits.  

 

I have also the Mephisto album ripped from my CD and it showed on my DAC that it is 17/44.

 

I am wondering where goes the missing bit or where comes the additional bit or my DAC is malfunctioning.

Searched on internet, it seems that HDCD if properly ripped will show 17 bits or more.  I usually turn off the display of my DAC, so I may not have noticed it before and other HDCD may be the same. 

 

Still does not understand why the DXD Polarity album is 23 bits.  Will see my other DXD or 2L albums tonight if they have the same problem.

Actually, the "Innocence" track from "Polarity" album is available on http://www.2l.no/hires/ and indeed sox shows that the least significant bit is not used:

You should ask for 1/24 refund 😉

yes, misrepresentation as 24 bits.  I was not worrying of the use of less one bit but the hidden use of the one bit.
