The recommended maximum level for DSD is -6dBfs, also known as '0dB SACD'
The maximum level that you can get away with printing on an SACD is +3.1dB SACD, also known as -2.9dBfs. Current recommendations (Derk Reefman, Irwin Jansen paper) strongly suggest not to go above 0dB SACD for any audibly significant time.
The default setting in several DSD to PCM converters is to add 6dB of gain to make up for this 'offset', but if you've gone over '0dB SACD' then you'll get clipping in the resultant PCM file when this default gain is used.
It certainly helps to have the ability to meter the DSD levels properly, either in software or hardware. I use the Sonic Nexstage 'AFC' software. The Korg Audiogate software is sonically a pleasant surprise, but lacks decent metering.

The DSD itself however was distortion free.
Then I tried converting with -6 gain and -9 dB gain.
This worked. |
