What we used to call a 'sweet top end' does indeed seem out of fashion these days, judging from reviews and comments from people who are not happy about it. In the past I have made statements such as "Half of everything over 15 kHz is hash" because even if it isn't recorded that way, so much equipment will add its own, anywhere in the chain, it seems. Not having any gratuitous tizz can sometimes be disarming, until genuine high-frequency content comes along to remind me that the highs are indeed there, after all. I'm missing my magnetic passive preamp - some electronics contribute so much of that crap that many people wouldn't even notice more added somewhere else, I think. My Rega Saturn CD player is the worst I've encountered in that respect, funny because I liked their (original) Apollo much more.
My prescription? A magnetic passive preamp plus two 'stats, before bedtime.
