I've did a quick research to see if this topic has already been discussed, and then I decided to open a new thread.
I've heard that some persons consider the SACD disc's sound played by high level player superior to the ISO extracted by the same disc and sent by a PC/streamer to the same DAC used. Actually, they’re arguing that the ISO itself is slightly less performant than the “original” SACD layer.
I can’t do a comparison by myself, but it seems strange to me.
What do you think?
