WOW! Lots of issues here. First, the japanese BB King on ebay recently showed 'RM' on the ubo, and I saw the photo. It didn't sell as the owner had an opening bid of $100, I believe. On the issue of the old blues qs's, I have the Nat King Cole. Although it is not mono, it isn't much to write home about. I have Larry Clifton's Quad Inc, and it says that Ed. T. Canby who was a quad devotee in the '70s and wrote for, I believe, Audio (?) termed it 'quadramonic'. That's a good name. As far as the 'quad compatible' qs's, I tend to agree with Cai. The problem is that many of the real command quads sucked too, so its hard to generalize. You just have to listen to them and then judge. On the Tommy qs's, I have the Ode LSO Tommy, and it is definitely quad, although not very aggressive. There is a thread in the Q8 section of this list about someone who tried a dts conversion of the Q8 LSO and he felt there was no quad at all. This confuded me, but if Cai is right and there may have been some stereo alls released with the quad label. This was definitely NOT a single inventory quad title. I have seen many stereo versions, and only mine and one other qs version. Mine has stickers on it covering up, I would guess, the stereo markings. It says 'Sansui QS' 'quadraphonic' on the front, the number is QU 89001. The record says 'quadraphonic' on each label, and the run out has the QU 89001 number and says '(QUAD)' on all four sides. I would guess that if yours has the stereo numbers on the disc, you may have gotten hosed. Did I leave anything out?
