It was the lossless claim that got my attention, Jens.  I am well aware that

current compressors can beat that at "acceptable" quality.  But an ogg at q7

turned into an  192k mp3, or vice-versa, results in a blurred cacophony of

noise because each compressor throws away different stuff.  The result is

still like fingernails on a backboard even to these 75 year old ears.
