Yes, the SACD (DSD) layer is superior to the CD layer. If you buy a SACD/CD transport so you can use an external DAC, then, the transport and DAC must match to avoid SACD sony copywrite issues. Otherwise, you need to buy an SACD/CD player with a built in DAC. Most SACD/CD players only output the redbook CD digital data through their digital connection, so, you cannot get to the DSD layer.
I have a McIntosh SACD/CD transport that feeds DSD through a special DIN connection to my McIntosh DAC. I also invested the time to rip all my CDs to wav files and rip all my SACDs to dsf files. I have loaded all these digital files into a 1 TB microSD card and play them through my streamer which feeds into my DAC through USB. This has basically rendered my SACD/CD transport idle. If you rip your SACD files (dsf files), then, you can feed them into any DAC you want. There is no copywrite issue to deal with.
So, for me, the priority should be to rip all CDs and SACDs into lossless files and feed them to your DAC. You can also use the files in your car, phone, etc... , and give them to your family & friends to enjoy.
Note: I will not sell my SACD/CD transport, because I still want the ability to play my media, but, the convenience of selecting your CD/SACD files from your phone to play instantly is outstanding. For me, with good equipment, the sound difference is indistiguishable. Note: My system is posted in my signature.
Note2: To rip your SACDs to DSD dsf files, you will need an old Sony Blu-Ray player like a BDP-S5100 that you can buy on ebay for under $50 or so. Then, you need a few commands that you put on USB stick, and the player will download the SACD DSD layer to the USB stick as dsf files. From there, you can feed the dsf files through USB or I2S) to any DAC that plays DSD. Piece of cake.
