In a display of ignorance from a soon to be HD621 owner, do all SACDs necessarily have high res data formats? Think someone said some Bluray's do not. In those cases, wouldn't we want no upsampling in the Oppo so the HD621 could perform it's magic? Is there any way to accomplish this with an Oppo? Thanks JimK
