Here's what my ears tell me: SACD beats normal redbook CD easily in the midrange and in the lower registers, but there is seriously something wrong with the top end. I't somehow dead, lifeless and something, hard to define unpleasant, unnatural in its rendering! At any rate - I have plasma tweeters from Acapella - I suffer from listeners fatigue after too long exposure to SACD, which I don't with vinyl nor generally with well recorded CDs and my SACD playback isn't cheapo, but pretty much SOTA. Cannot say if my experience has something to do with the findings in the above mentioned article, but John Atkinson has in his testing of an Accuphase player published results, which point in the same direction. So, sadly, I've come to doubt, that SACD is the great breakthrough to finally fullfill the promise of CD. Natalie may well be right!
