I play mostly sacd iso with mc28, mac os big sur (bitstreaming). I noticed the iso tends to sound brighter than if converted to dsf/dff, mostly heard in vocal sibilance and maybe a tad less low/ low mids. I tried to avoid converting to dsf/dff because of clicks between tracks( still occurs with iso , but less often). What's happening in the conversion process that is smoothing out the sibilance? Are there settings that can be tweaked to smooth the iso out a bit in real time? This occurs with dsd and dst isos.

Don't use Media Center's conversion features to create DSF/DFF files from a SACD ISO. Not only does the conversion have to go through PCM in the middle (DSD > PCM > DSD), they're all lossy conversions.
Use ISO2DSD with sacd_extract to extract (without conversion) DSF/DFF files from a SACD ISO.
There was a whole topic recently about this, which I suggest reading here: https://yabb.jriver.com/interact/index.php/topic,131979.0.html

i don't. I have sacd_extract and that audio inventory application.
besides, i prefer the sound of dsf/dff compared to the iso ,when using these application .

It's literally the same though, the data in the DSF/DFF file is 1:1 the same from the data on the ISO if it was extracted correctly using sacd_extract when extracted into an individual file inside a DSF/DFF container. There shouldn't and wouldn't be any sound difference at all because it's exactly the same as the source, just inside individual container files (and it being in a container wouldn't make any audible difference). The data/audio bits are unchanged and there should be no audible difference between the SACD ISO and the DSF/DFF extracted files.

Have you compared an sacd iso and dsf "extracted correctly" from that iso? Check it out. It's subtle, but there is more of a vocal sibilance. Why would the correct one sound worse?

should my AP hybrid sacd iso of 'Elvis is Back' and the AP Dsf version from acoustic sounds sound the same? They don't with MC 28/big sur.

It sounds exactly the same, which is exactly what I'd expect. If you're hearing differences then honestly it's either placebo or something went wrong when creating the DFF/DSF files and they went through a PCM conversion step, because it doesn't matter if it you're listening to a track on a SACD ISO or an individual DSF/DFF file of the same track, the data is exactly the same so it'll always sound exactly the same unless some sort of conversion happened.
It makes NO sense that there's be any audible difference between a track on a SACD ISO to an extracted, individual DSF/DFF file.

nope. none of the above
