I purchased DXD in 32 bit (float) format from NativeDSD. Useful if anyone plans to process it any further, I prefer the 32bit version over 24bit for my use case.

Wondering if there are liner notes in pdf form. The DXD download did not include anything. 

 

I love liner notes. Whenever I rip a disc I scan the liner notes and put them with the files - and can see them in Roon or Audirvana.

@miguelito FWIW: My DXD download included the liner notes as pdf. I did a direct download (did not use download manager), the album was downloaded as a 6.5GB Zip

They didn't have the 32bit listed at first. It's a later edition. The 32 bit is the actual master. Although I'd be surprised if anyone can hear a difference between that and the 24 bit conversion.

I have the actual master. I will have to snag a 24 bit sample to see if I can hear a difference. I probably won’t be able to.

The 32bit version is floating point as DAWs do the processing in floating point and  24bit is created from the floating point version. 

But  I don't know of any DAC that can directly use PCM in 32 bit floating point values. So most likely your music player will convert 32 bit floating point to either 24bits or 32bit PCM, at which point it would be hard to distinguish. The 32bit floating point is most useful and will shine if you do any kind of processing (EQ,  software volume control or upsampling).

Yes, my software sends the DXD files at 32/192 to my DAC. The 24 /352.8 would be sent at 24/192 so I can’t imagine being able to hear a difference.

It will be interesting to see if you hear a difference, and only because your software is having to downsample DXD to 192kHz rate, so working with the master can have have some benefit.

Hi ZB,

 

The 32DXD was not available when I downloaded the 24DXD.

Is there any point in the 32bit version if using PGGB to output 24bit for use with SRX-DX?

Since you got the 24bit version , perhaps you can reach out to NativeDSD and ask if you can get the 32bit version (assuming you got it from NativeDSD).

 

The 32bit version is floating-point and it is the source you use as an input for further processing. Having a higher resolution source is beneficial wether you output 24bit or 32bit as the processing benefits from the increased resolution and decreased noise in the source track. The only time 32bit float version is not recommended is when you wish to play it back in a bit-perfect mode with no processing.
