I could not disagree more, if the SACD was originally recorded in multi-channel high resolution and not badly re-mastered. Most classical SACDs have superb sound.
By the way, hybrid SACDs have two not three recorded layers, one for the CD layer and one with much higher information density for everything else. There is enough room for both 2-channel and 5.0 or 5.1 channel DSD versions.
I could almost immediately tell there was something wrong with DSD playback through my then-new Reavon player's internal DACs. It turned out it was down-sampling DSD to CD-quality PCM. It is fine when used as a transport with external DACs which decode DSD natively.
Note that by DAC I mean a chipset, not a box containing DACs!
