Is this mix different than the DTS version?
I believe they are both the same Quad mix but sound a little different which I put down to the re-purposing of the the Quad to 5.1. The DTS seems a little clearer, brighter and crisper and for whatever reason a little bass shy (which of course was its primary complaint), the Qaud reel conversion seems a tad duller (not that it is actually dull, just in comparison to the DTS) with the bass a little more pronounced.
