I have heard the Mapleshade and find the performance substandard. And Mapleshade still suffers from the glass-mastering and stamping variations in the existing manufacturing process (which is exactly what the XRCD process has improved). This is why I call it the 'Jitter Bug': unless your equipment reclocks the incoming stream, CD playback will have a level of jitter *in* the disk which can't be removed.
