I just bought a Denon 1930 CI and I'm extremely happy with it.  I think it will do everything you want, HDMI, SACD DVD Audio, 5.1 outputs, except play multiple disks.  I have not had any issues with noise, although the tray is extremely flimsy.  It's curious because the player is, otherwise, a quality unit.  I know that the sound quality is supposed to be the same with any player using a digital connection, but this one sounds much better than my old Sony player connected with toslink.  The sound with SACD disks is amazing.  It's a shame that there isn't more support for that format.
