SACD vs Regular CD's

I have a fairly good system, through which I have been listening to CD's with a Meridian G08 player which I have found to be fairly close to the analog sound. My question is, I am also thinking about getting a SACD player. I have NO experience with SACD's: are they worth the investment? is there really that much improvement? what are the pros and cons of SACD?

Any help would be appreciated, and I thank you, in advance, for any helpful comments.

Regards,
