... because the stop band is increased from 20K all the way up to the new sample rate, instead of being in the narrow band from 20K to the CD sample rate Nyquist frequency (22.05K). So apparently you get can get rid of brickwall filtering just by upsampling, which on the surface seems too good to be true :)Of course you are right that nothing new is created, and there will always be some degradation, but getting rid of the super steep filter could make a difference.
