With something like 5% intermodulation distorton - something rarely talked
about with analog media. To my ears, that muddies the audio a bit, especially
when there's massed vocals or instruments. But my sensory processing is likely
different to most.
A lot of people do say CDs sound "harsh". The cause of this, from what I've
read, turned out to be the sharp cutoff above 20 kHz, due to the anti aliasing
filters and relatively low sample rate. At one stage, a CD player was
released, which deliberately allowed aliased audio above 20 kHz to bleed
through, and apparently, people did find this one less harsh. Vinyl can
reproduce ultrasonic frequencies well, especially with the right shaped stylus.
This capability has been used in the 1970s to enable quadrophonic LPs to be
pressed.
And yes, before you say it, MP3, AAC and other lossy compressed audio can sound
noticably degraded too, though in different ways. Certain audio tracks really
show up these issues. And oddly enough, for me, VBR compression seems to sound
worse than CBR to me.
