Playing SACD on a Non-SACD Player

No. In fact, your redbook player will not read an SACD single layer disk at all, and on a hybrid disk it will read only the redbook layer.

You can only play hybrid SACD's on a redbook player. There are two layers (redbook and SACD) on these types of discs. A redbook player can not read the SACD layer. If it is a SACD only disc, a redbook player will not read it at all.

Some people say that the redbook layer on dual-layer SACD's is inferior to standard redbook. The claim is that the industry does this to make listeners unhappy with redbook. I don't own a SACD and so haven't been able to verify this. But I steer clear of dual-layer software.
