I found another Q8 from Arista with some previously unknown quad mixes, although they may not all be real quad mixes, it's worth pointing them out. The Q8 has no claims to be quad, but it does have the quad notch, and the two programs have four channels. Most sound like they could be stereo mixes put through a QS decoder, there is definitely EQ manipulation, a lot less bass on the rear channels, and a bit less treble also. Once I adjusted EQ on the 4400, there was less difference between the rears and fronts, but the rears had more separation than the fronts. One track, Gil Scott-Heron's "Johennesburg", sounds like it could be real quad.
