two gripes to get out of the way -
i.)..the centre channel is underused.. hardly anything happens in it.. I like Billie's distinctive voice and I'd prefer to have her lead vocal hard in the centre with lead vocal ambience spread across the front L&R..
..and ii.) the disc is mastered a bit bright.. in certain spots percussion crashes etc are just that bit too overcooked for my tastes.. and the rockier material may have benefitted from Hi-Res..
The answer to the above is Brad. This was his disc and even though DTS wanted us to have a center channel, this was done in quad way before the 5.1 insanity was born. This was ready made like the mystic moods which he also owned, and he could get them ready for a start on a DTS catalog. Quad when done correct is much better than the center channel destroying the soundfield, and that was his way of thought also. And the brightness thing was his too, Abraxsas comes to mind. I got to give some feedback when around, and i remember dialing in Stills for him, which still sounds pretty good. I think his hearing was being affected a bit, it was only a couple years later that brain cancer took his life.
The timeline might be good if we could post it somewhere. Maybe i should do some sort of timeline about the quickness that things changed during that era that the Millennium and DTS began the 5.1 era. There was no hi res anything back then, In 1996 that was fantasy, the chips were just being developed for that. After the first iteration of the Mill, i was asked by the fellow designing chips at Motorola if we wanted to do the next generation first, test pigs again. The chips to do both DTS and Dolby on one chip had just been developed in 1997-8. Wanted to know if we wanted it, we had 6 months before they gave it to Denon and the rest. The time was too short and adds to expensive. Interesting time.
