Comparing SACD sound to High Res

Sure. All the time and to DSD downloads as well. For me,
the real differential is the performance and audio
production because they vary so much more than do all the HD
formats.

You will/may get more comments but until you do try this for
yourself, comments (including mine) from others are
unimportant.

Email Barry Diament---he does pro recording in lots of sampling rates.

Both have their virtues. Just because you have SACD or Hi Res doesn't mean it's good. Personally I love both. I usually stick to SACD on my theater and Hi Res on the 2 channel tubes.
Buy both, SACD's take a few days to ship. Download a couple of HD's over those few days, then compare for yourself. Then, go buy some 180 gram vinyl and really stump yourself. They are all awesome. Just enjoy the music.

Thank you for the posts. So, I am understanding from input that SACD can hold its own with all the new high res download formats, making the performance and recording quality more of a factor in hearing stellar, engaging sound than what high res format it is in, correct?

You got it Gammajo!
