Blu-Ray.com Writes:From what I can tell, this new edition seems to retain the same lossless DTS-HD Master Audio 5.1 surround track of the previous release, and that's a good thing. As Marty noted in his 2008 review, there is a slight hiss at times, but it's really only apparent if you're actively listening for it. For the most part, this is an impressive mix for a film from 1970.
