anyway, the most important thing in this thread that's gone rather scarily OT, is that the Tommy Quintaphonic movie soundtrack on DVD/BD and the Tommy movie soundtrack Stereo album are absolutely not the same thing! phew! glad we cleared that up (thank you, Doctor)
now onto the next stealth Quad (that i hope really is a Stealth Quad!!
Note that John Woram former quad master engineer for Vanguard Records made this page up of what he thought of what were the best albums of the 3 competing vinyl quadraphonic systems.
IIRC Mr. Woram ended up with his own quad consulting agency sometime after leaving Vanguard , and became a huge backer of Discrete Systems. Namely broadcasting and CD-4 .
He wrote articles published at the annual A.E.S.
Anyway I thought it worthwhile that of the Sansui QS albums he found best were 2 popular selections from Vox , Larry Fast's Synergy , and The Who Tommy soundtrack.
I find his review of the Tommy Polydor album very revealing , and pretty much the same as what I heard on my Sansui QSD-2.
Now of course the Blu-Ray blows the vinyl album out of the water as far as the surround mix goes on the Polydor album.
And I notice that the original mix may not be Ron Nevison's 1975 mix , but a slightly different one by James B Young and Greg Faust . Of which I find to be far more superior to the original.
Now of course we now have 5 Discrete sounds that can be accurately heard on the Blu ray , in whereas back in 75 there was only one , the center . The other four were from a QS Decoder .
I also find it interesting that so many version tapes were made , such as mono , and Dolby Stereo ( 3/1).
But as the finality to this Quintaphonic experiment I know of only two music films that were made and unfortunately Quintaphonics died an unfortunate death mainly because they could not outcompete with the well established Dolby Stereo System adopted by Hollywood.
Additionally there were other 5 channel matrix systems that tried to obtain acceptance , such as Ultra Stereo , Chace Stereo Surround , and Shure HTS , but all failed eventually because of Dolby's well established clout .
Whew !
