The Sony NS-999ES and Denon DVD-2900 both have fairly large linear power supplies. Redbook CD is fairly good with either, and both play SACD. Only the Denon handles DVD-Audio. The similar current Denon appears to be the DVD-3910. The DVD-2910 seems to have a much lighter build quality and probably uses a switching power supply, but I have not actually seen the interior to confirm it. Good luck!
