SACD vs DSD Files

Hope I pose my question correctly so that it makes sense.
I have a few SACD’s and used to think that when I was listening to them, I was getting the full sound or benefit of the SACD.
Then I read about I2S connections on PS Audio and how they described hearing the DSD layer on the SACD if you use their equipment.
I also have a few DSD albums that I downloaded and listen to.
So my question is, if I had equipment that could actually decode the DSD Layer on the SACD (similar to PS Audio), would it be pretty much the same experience as listening to the DSD File version of the same SACD?
Hope that makes sense.
Trying to get equipment that could handle that just to play a few SACD’s, would be too pricey for me.
I found a company that rips SACD’s to DSD, that would be a much cheaper way to listen to the DSD version of the CD in my opinion.

What do you all think?
I want to get a better CD transport in the future but not all play SACD.
Thanks
