Yes Dartford, the stereo DVD-A 24/192 does exist! You will find it on 2 or 3 releases of a label called "Surrounded By". Their discs contain both a 24/96 surround mix, and the aformentioned 24/192 version. In order to play the latter, one must select "group 2" before initiating "play" on your DVD Audio or Universal player. This may require the use of a video screen, although the recently released Esoteric DV-50 allows this choice to be made using the front panel readout.
