Ripping of SACD Audio Files-DFF and DSF

clplarry

Has any brother compared the difference of DFF and DSF files ripping from a SACD ISO file? I experienced that the size ripped to the DFF format was just the same size of the original ISO while that ripped to DSF format was over double the file size of the original ISO. It is reasonable to have the same size after rip because all of them belong to DSD files. Why the size of the DSF was so great after ripping from the ISO? Is it a form of distortion in this case? I would like to have the comments from some experts here! Thanks

I have just found why should have this case happened. As some of the SACD iso files were compressed, they would be automatically decompressed when ripped to DSF format with a much larger size than the original ISO files while the size remained the same as the original ISO file when ripped to DFF format without clicking against the box "Convert DST to DSD". But the ripped sound to DFF in this way is abnormal with cracking noises as long as the music is on play. Ripping to the DFF format with the box opted for "Convert DST to DSD", the ripped file size is just the same as that ripped to DSF format. I am sorry no any brother gave me the description about this!
