Various CD Formats

What brand and model CD player do you have? A "regular" CD player will play regular CDs, and gold CDs and XRCDs are just variants of regular CDs, so you can play them too. You can also play HDCDs, but unless your CD player is capable of decoding the HDCD encoding, you will not get the benefits of the HDCD encoding-- this is also a CD variant.

SACD and DVD-A are new high density discs that will not play on regular CD players. But, some SACD players (all?) are also designed to play CDs, but of course only at the CD Redbook standard of 16/44.1-- these are "regular CDs". Good Luck. Craig
