"Some say even on a good system which is set up properly that they can not notice a difference between SACD and standard CD."
That could mean just about anything. SACD's do sound different than CD's. The problem with most people is they don't do it right. Quite often someone will have a really good, high end CD player but go out and buy something cheap to try SACD. They figure the format will be so much better than CD they can get started with something very entry level. That's a lot to ask. Under those conditions, you may very well like the CD better. A much better way to compare is to get a player that supports both formats, and use that for testing. That way, you're more likely to hear differences in the format and not the players themselves.
