I agree with Natalie. I have yet to hear an unmodified Sony SACD player that has sounded any better than mediocre on redbook CD. There is something amiss with either Sony's DAC and/or output stage. This will draw jeers from all you Sony fans out there, but in my opinion, the $198 Apex DVD player sounds noticeably more musical on CD playback than the SCD 777es. Just my 2 cents. Unless you are bypassing a preamp and going direct from whatever digital source you have, don't worry about having one player. Get what makes your CDs sound the best to you right now and worry about SACD if and when you feel you must have it.
CD v. SACD
I was planning on buying a new CD player (Rega Jupiter 2000), when I read a few reveiws of the Sony SCD-XA777ES, which used, I could buy for about the same amount as the Rega new. I currently have an extensive CD collection, but no SACDs. My question is whether I should just go ahead and buy the Sony, or whether a dedicated CD player, like the Rega (or others at its price point) are significantly better in their CD playback. Thanks.
