A nice rewind on the Quad debacle can found here. Internal views of the original Q-X949 you know where. The beautiful original 1974 US sell-sheet for the 949, right here. Wonder how the cool display of the 949 really looks like? Go!

The 949 was reviewed in the april 1974 issue of AUDIO.

Below is the little QX-646 which doesn't seem to have survived 1976 and, therefore, no "A" version either...
