Re: A/B listening tests
hello bill, you write: In any digital system, distortion goes up as you
approach the lowest volumes.
i am curious and would like to experience that. any suggestion for a setup
to experience this?
(equiment: pc into tc konnekt into sennheiser hd 25, 39 year old male
are you talking about actual distortion, like in: oops, the red lights
or change of sound color?
or is it the kind of warbling noise that comes up if you sample something
soft and turn up the volume?
