It has to be a native format that exceeds Redbook CD resolution otherwise there is no inherent added value.
DVD players and Blu-Ray can both exceed CD.
DVD format can contain up to 2-channel Linear PCM audio data ranging from 48 kHz/16-bit to 96 kHz/24-bit
Blu Ray format can contain up to 2-channel Linear PCM audio data up to 192Khz/24 bit (not sure if any products exist like this yet on BD discs - it would use up a lot of the disc space)
Both support a variety of compressd formats which would not interest you. With most movies you are hearing a compressed audio format(like Dolby and DTS), however DTS is generally preferred as it is 20 bit versus Dolby's 16 bit.
There is not much of a market for two channel Linear PCM of high bit and sample rate - so I am not sure what you can find - Chesky made some stuff and so have other audiophile labels, however, these are often of artists that you probably don't want anyway....
