Hybrid SACD's have two formats, SACD and RBCD. These hybrid CD's will play on either type of player. SACD CDP's will usually default to SACD layer, but on some at least on my Marantz you can also select RBCD layer instead of the SACD layer. The hybrids should play on any CDP - that was the point in making them hybrids.
Re differences in sound I assume you mean an ordinary redbook CD and the same performance on hybrid disc played back on a redbook player. I've never pinned down a difference in sound quality. The obverse is not necessarily so on my Marantz SA11s3. It has excellent dynamics, more so than my other CDP's, and it seems that ordinary redbook CD's take on that quality, but I don't think this is anything inherent in the CD itself.
FWIW.
