I concur with the idea of a transport + DAC vs a stand alone CDP. The DAC inside of a CDP will eventually become outdated IMO. As long as a transport is working then it can be matted with an unlimited amount of DAC's through the years, so why pay for something you may outgrow, or not use with a CDP with built in DAC. Just doesn't make sense to me. The downside of this course of action is obsessing for ever and a day on which DAC to use. This method does provide far more flexibility in the future too, should you need it.
But to respond to cd players only, as requested, you might consider used Arcams which hasn't been mentioned, used Oppo's, and Emotiva makes a great CDP the ERC-4 but you could probably find some used ERC-3's too, Audio Lab makes great products as well for sensible prices.
