An Oppo-203 has an HDMI In, and it will decode it to its second HDMI Out, or so I'm told. I've not tried it myself as I have an Oppo with a Vanity board (digital coax out) so I go straight to my 5ks.

They don't make it any more, but as far as I can tell, its your only option. They go for about $1200 on eBay, and it’s worth it.

With our speakers, the difference between TrueHD and DTS was clear even to my wife (who usually doesn't care about such things).

If you can find an alternative please let me know!!!
