Hello John; the 333es has the Turbodacs that the SCD1&777 had all being stereo machines.Aside} the 555es is multi channel and has a different DACs & other components as well. I am sorry to tell you that only some SACDs are superior sounding to their CD counterparts.
My 333es is much modified with AD8620 amps out and some Black Gate caps; All on the audio board have NX .47 bypasses
around them. The regulators are changed also. Yet with all this work I cannot play 24 bit CDs in the 333; yet they will play in the Sony 2000 changer; which also plays SACD. It is a question of where you want to go with the music. For me stereo is complicated enough. From an engineering standpoint surround recording is still in its infancy.Where do you want to go?? Robert
