You must have a lot of noise or very, very good ears. Most noise floors
are way below most folks hearing.


It doesn't really manifest itself as "noise" in the traditional sense. It's
more like the music emerges from a "deeper black" background. I know that
this may well be my imagination, but I noticed it right away on one of my own
24-bit/96 KHz recordings. I thought I knew this particular recording
perfectly, but never had the background been so velvety quiet. There was
always some sound even when the ensemble was not playing, rustling music
sheets or squirming in their chairs. But not any more... Not at all
scientific, but there it is.
