Comparing SACD sound to High Res

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!

Gammajo,
Not quite. Not all sacd's are recorded/mastered/remastered at optimal quality. This also applies to cd's and hi-res files, whether pcm or dsd. The final sound quality of any format depends on the quality of the whole production process. So, well-produced cd's can trump poorly produced sacd's/hi-res pcm or dsd files. That said, if all things are equal in the production process in terms of quality, generally sacd's should sound better than cd's but if compared to hi-res pcm files, the jury is still out. It all boils down to a matter of taste, or listening with our own ears.
So,how do we know the sq before we buy? Reading music reviews help a lot. Recommendations from music forums like the one here in A'gon are very helpful too.
Happy hunting and happy listening! J.

Jon2020, I believe that's what Gammajo said here:
