The SACD layer on a hybrid disk is a file in the DSD format. With a few exceptions (PS Audio, Others??), a disk player will not output the DSD file from an SACD to an external DAC where that file will sound its best. That's because of restrictions placed on the SACD format by Sony, its inventor.
So if you want to play the SACD format file through a good external DAC you have 3 options. You can buy one of the exceptions, you can buy the DSD file from an on-line seller, or you can rip the DSD file off of an SACD and play it on a DAC that will accept it. Most, but not all, will. You can rip it yourself, or pay someone to do it. All of these have the same sound potential, varying only by the quality of the equipment used.
Many, many audiophiles do the ripping themselves.
