Beethoven Symphonies 1-9

Richard Osborne in the December 2016 Gramophone at pages 51-53 condemns this box for weak sound quality. The presentation of technical information about this box seems confusing. Nobody seems to want credit for the video. One has to wonder if sloppiness in the cover also suggests carelessness in the recordings. Can you sometimes judge the book by its cover?
