Somewhere above I termed the Valois CD transfers of Chapuis (from Telefunken vinyl) to be "vivisections" of the original sound. And said the vinyl sound was far closer to in-person organ performance sound than the CDs. I just recalled one exception. To show us some point or other about sonic qualities (can't recall exactly what), Fenner had each of us in turn climb one of the maintenance ladders affixed to the Flentrop's back case, and stick our head through an open maintenance door and into the organ chamber. Then he, seated at keyboard, blasted out some music on that division that our head was inside of. THAT sound, I just realized, is what the Valois CD sound might be closest to.
