Do you mean does anyone have equipment that decodes/plays these formats? I doubt you'll find many people. So far, it looks like there are only a few BDPs that pass DD-THD & DTS-MA as bitstream to a receiver. And there's hardly any affordable receiver that decodes these formats. The Onkyo TR-SX605 seems to be one such receiver with good reviews.
So far, the height of multi-channel audio tracks for us seems to be regular DTS!
