If you're going to use this machine to watch movies, then the CA blue ray players or Oppo will be just fine. If you have a lot of SACD then I'd look at Marantz. Can't speak on the Oppo 105d, but I think the CA 751 is probably close. I can tell you if you're primarily listening to red book cd's, a CA 851C is far better than the CA blue ray machines. As far as your CAL goes, any of the machines you noted will be better. CAL's were very nice machines in their days and still good today, but not up to these machines. If you have a lot of SACD's don't overlook Marantz.
