I have a 2-channel SACD system (please click on my "system" link for more details). I purchased speakers that are (a) meant for SACD (slightly higher frequency response...if my hearing even warrants it), and (b) are meant to be expanded into a 5-channel system if I so choose (with other models designed for just that purpose).
My understanding from friends, Audio Asylum postings, and personal experience (on other systems) is that many 5-channel recordings are a little "gimmicky." Remember, engineers, even SACD engineers, have not been in the 5-channel recording game nearly as long as they've been working with 2-channel recordings. Of course, word is that some 5-channel recordings are extremely well done, but they seem to be few and far between.
All in all, 2 channel SACD is definitely worth it, in my humble opinion. Besides, you can always add rear speakers and a center channel later on...once SACD has full bass management and time alignment (a whole other thread...)
