Alas, you are probably right. Into oblivion it goes, with the rest of broken promises and shattered dreams.
Audio Fidelity has picked up some of those shards of shattered broken dreams with fulfilled promises. I think giving AF time to work through the available titles, and giving thanks for them by buying them. We should then start hammering Rhino for the resurrection of the Quadio line.
Probably the right time to start hammering them over the head with emails and letters is just about the time Aretha has finally sold out. This will happen sooner or later. I don't think they pressed up that large of numbers. And also not before AF has had time to get out the best of the non-MFSL reissued titles from Warners.
Just to show respect to AF, I don't think now is the time to ask for quad directly from Sony or Warners. Letting AF get everything good that they can first is a good bet imo.
