I remember in the late, '90s Technics used to make an outboard DD/DTS decoder (SH-AC500D) with coax/optical inputs and a 5.1 analog output, for the benefit of certain mid-'90s receivers that had a 5.1 input but no DD built in. I have a Sony receiver from 1999 with a 5.1 analog input. It has DD and DPL (not DPL II) built in. This is fine for me, except many Wii games use Pro Logic II, and it would be really nice to add this without buying an all new receiver. I'm totally happy with this one and it would be practically worthless on eBay anyway. Has anyone made an outboard processor that can handle Pro Logic II?
