Thanks to everyone who's commented on their enjoyment of the mixes! I'm really glad that they add positively to the film experience and that they sound as though they could be the real thing. My goal was simultaneously to be as authentic as possible and also to create the best-sounding versions I could, and it's great to hear that my estimation of them has proven successful.

As to differences in volume level, I quite honestly have no idea why they would be perceived that way. Aside from the addition of bass and the bits that had to be replaced using the '77 stereo mix, the vast majority of it is still just the 1993 version, which was made primarily as a direct downmix from the original 70mm printmaster and should be pretty much identical. I avoided the use of DialNorm and dynamic range compression so that the overall volume would remain identical to the PCM tracks on the laserdiscs. The LFE channel of course adds considerably to the loudness when present, and the replaced sections are unavoidably less dynamic than the original would have been, but on the whole it's about the same. Different equipment may handling different formats in ways I don't know about, or individual perceptions may be colouring the results.

Do the DTS-HD MA encodes contain DialNorm, by any chance? It is a part of the specification, unlike earlier versions of DTS, but I was under the impression that the option was turned off by default. If it has been enabled, it may explain why they seem to be less loud than the AC3 tracks, but adjustment of the receiver volume would compensate for any discrepancy during playback.

Most of the feedback has been on SW, which is of course understandable since it's the most strictly authentic of the mixes I made, and the film that gets the most attention in general. But I'm quite interested to hear any impressions of the mixes for ESB and RotJ, as well. ;)
