And in answer to the other question I did a direct A/B - in each case the deeper bass and greater dynamic range (the range between the quietest to loudest sound) turned out to be the 'Faces' LD.
To be perfectly fair though without having first heard the laserdisc I wouldn't know what I was missing, but as the 16-bit PCM track EXISTS and COULD HAVE BEEN USED on this release, it's a crying shame they just went with DD only.
