You've got it in the right category all right.
If you have no luck here at AC you may want to try listing it over at Videogon. That's the sort of piece that has outdated video capabilities, but very nice sound qualities... and someone with a Blu Ray player that outputs decoded DTS HD Master and Dolby True HD CODECs on its analog outs could be mated up with it with very fine results.
Good luck.
