MrT, are you saying that you don't like the harsh, shrill sound of many CDs and most CDP? Well, we can all agree on that. There are players that will eliminate that on most CDs (some old stuff from the 1980s just can't be rescued, IME). That's not hi rez sound, IMHO, it's an inferior attempt at hi rez that merely substituted one inaccuracy for another.
As for calling a recording (I'm assuming a good one) "an inaccurate representation of a live performance" consider actually attending a live acoustic performance. It'll sound different from every seat in the house. Those of us that like detail sit closer and you that like a homogenized sound sit further back. Neither position is "more accurate", it is what it is. Recordings are no difference.
Mic coloration in classical recordings, these days, tends to be very small. The Tacet recordings, in particular, are very cleanly recorded. I heard Reference Recordings from the hall and on CD or vinyl and they're very, very close. Played in high resolution, these recordings are simply wonderful.
Hi rez does not include, uptilted highs, high frequency haze or artificial harshness, IME. Many high end (read as expensive) systems DO have uptilted high, high frequency haze and artificial harshness, because there's some failure in the sytem, IMHO. This is not unusual and I'm thinking that this is what you've heard and rail against. I don't blame you.
Also I understand your seeming disgust. There's a dealer here in the Denver area that sells poorly set up Sonus Faber speakers. If you were to listen in their showroom you'd probably wretch at the etched, harsh sounds coming out of the system. When questioned, they sniff and say that's how they're supposed to sound and lots of people buy them because they're so good. I'm frankly amazed that they sell anything. Trouble is, the Sonus are not the problem, it's that dealer's poor setup.
That attitude is fairly persistant in the audiophile world and it's hard to find a really sweet sounding hi rez system (there usually in someone's home) but when you hear it, it can be a revelation.
