I don't know of any, sony did make a pre with two sets of inputs at one time, they come up used here and on e-bay every now and then. You could go with a switch-box if you can find nothing else at a good price.
Are there any receivers that have dual 12 inputs
I'm looking for a receiver that would allow me to hook up a SACD player and a DVD-A player. I know I could just buy a universal player, but upgrading my receiver is my priority right now. I have way to many DVD-A disc to just switch over to SACD only. If I could find a receiver that would allow that, I could eventually replace my wifes TEAC multi-disc cd player with a sony C222ES player and have it all.
