I don't think I have a player that accepts SACDs, currently.
SACD should play in many DVD, most Blu-ray or 4K players. But to decode all the layers with surround, etc. properly for each format, you really need a player designed to meet the SACD specification set.
I have an older Pioneer Elite Blu-ray player that has the SACD logo on the front panel along with about twelve other decoders built in. Also an even older Sony DVD I use in the garage will play
all but the highest resolution two channel layers on every SACD I've tried on it.
That's a compromise, but while some SACDs include Redbook layers, the "better" two channel layers on most SACDs are still higher res than anything that is possible on a typical Redbook CD.
Most folks can hear differences for themselves between CD and SACD, but the more telling point becomes more about whether anyone really cares about finer playback quality these days. Our numbers are dwindling.
With hardware media constantly dropping in sales across the board, I fear that the doom of SACD and possibly a few other formats may be closer than we know.
