I had a MH cd25.2, and I never had any trouble with mine (although Grinnell isn't the first I've heard about who did). Very transparent sounding player, and the transport was silent (on mine, anyway). I listened to the NAD and thought it was equally good (with a different, fuller sound), but I could hear the disc spinning from five feet away. Don't know about the Denon (I've heard their older players were excellent), but the MH was loads better than my Rotel RCD-950 (I'm sure the 1072 is a better player, though). Hope this helps.
