I always thought the Haeco-CSG system was intended to create stereo records that were compatible with mono phonographs. In any event, hearing a recording that was processed with it, and the same recording without it, you can hear the damage it does to the sound. Part of the idea was to alter phase relationships, keeping everything essentially in phase, to make sure it's all heard in mono. That would destroy creating a quad effect with a matrix decoder. I'm glad the system wasn't used for all that long.Assuming that the Herb Alpert disc was not intended to be surround, know that most of the Herb Alpert record albums were made using the Haeco CSG (Compatible Stereo Generator) years before there was any quad. They produce sounds located in the SQ back speakers and in the BMX front and back that ordinary stereo records do not make.
UHJ is actually not very far from QS in actual encoding relationships. It should play with slightly reduced front to back separation on QS. This is easy to understand using the Poincare sphere.
The phase relations for positions on the sphere are:
Green - in phase (QS front)
Violet - 180 degrees out of phase (QS back)
Cyan (far side of sphere) - Left channel only (QS left)
Red (near side of sphere) - Right channel only (QS right)
Black - Left leads right 90 degrees (SQ left back)
Brown - Right leads left 90 degrees (SQ right back)

The following show a sound panned around the room clockwise starting at the front:
QS uses the great circle for the equator green-red-violet-cyan-green
BMX uses the great circle for the meridian black-cyan-brown-red-black
H uses the 45 degree tilted great circle tan-red-blue-cyan-tan
J uses the 22.5 degree tilted great circle using:
- a point halfway between green and tan
- red
- a point halfway between violet and blue
- cyan
UHJ is not a great circle, but a smaller circle, using:
- a point halfway between green and tan
- a point between red and pink closer to red
- a point halfway between brown and blue
- a point between cyan and pink closer to cyan

well, it's the next best thing....Ah just saw I'm in the surround master department
I can see that!Tom Jones Gold - so good I want to throw my underwear at the speakers....

I can see that!
I was never a huge Tom Jones fan; but saw him on TV recently with a small concert he did with Alison Krauss (of all folks) and I was very impressed, he had a really great rockin' band backing him up.
