Guss2...The DVD-A which have particularly impressed me are Tacet discs of classical chamber music. These are from a german audiophile outfit, and will set you back almost $30 a copy, but are well worth it IMHO. I think that these exploit the full potential of multichannel, which I gather is not your bag, but the audio quality ought to be good for a stereo downmix, although I have not actually tried that.
There are few 24-Bit 192 KHz Stereo DVD-A released, but there surely is a lot of potential in that format.
