Differences in SQ can be due to a variety of physical factors including quality of power supply, noise levels, equipment compatibility, etc and some psychological factors including expectation bias, placebo effect, being used to a systems sound characteristics, etc.

Your audio device prolly has a USB receiver chipset that only accepts 32-bit word length. This is pretty common these days. In this case Linux/ALSA will automatically zero-pad the bit depth to 32-bits. This does not change the original 16 or 24 bits of audio in the samples and does not affect SQ.

DSD stands for Direct Stream Digital. It's a 1-bit (or multi-bit) audio format based on Pulse Density Modulation (PDM) that was used as the format for the Super Audio CD (SACD) created in the late 90's. The SACD was supposed to be the successor to the PCM based Compact Disc (CD) but it failed in the marketplace for a variety of reasons.

As a result there's not much music in SACD format. What little there is is typically ripped into a file format named DSF which contains the original DSD bitstream from the SACD plus metadata for each of the tracks.

moOde can play DSF format files in three ways.

1. Native DSD bitstream -  The audio device has to support native DSD
2. DSD over PCM (DoP | DSD encapsulated in PCM) - The audio device has to support DoP
3. DSD to PCM on-the-fly conversion
Enjoy the Music!
