dBpoweramp (https://www.dbpoweramp.com/) is a pretty good any to any audio converter. I don’t know if that will help you do what you need to do or not, but I find it to be a great CD ripper and general tool to have on hand.
DXD sound really amazing i like it; even more than dsd; maybe because almost all dsd is from DXD?
Ps thé DXD we buy today is 24bit bit dxd is remastered at 32bit?
