CD players seem pretty outdated nowadays. I even replaced my laptop's CD drive for an SSD - because I download nearly all of my music online, and when I want to rip a CD I just plug a drive into my eSATA port. But I was looking for a CD drive to complete my new stereo setup - which I don't think I am even going to get because I have a turntable for my vinyls and my laptop for everything else...However, I found that there are a lot of 24bit CD players on ebay that sell for 2 to 5 thousand dollars! As far as I was aware CDs are physically 16bit storage devices. Am I wrong? Are CDs actually 24 bit, or are these multi thousand dollar CD players just complete gimickes?
There may be an advantage if the CD Player is used with a build in volume control or if it applies things like de-emphasis. 24bit precision can help here to have enough headroom.

Just for interest sake, what benefit does a volume control give at other levels of the audio chain (like at the DAC)?I always just change the volume right at the end of the audio chain; usually at the amp.
