But the difference can be heard.
To hear the difference Monitor Headphones is needed. DJ headphones are not suitable.
At least not all of them is suitable. I use Philips SHP8500\00. They were enough to hear.
We must listen to the overall emphasis, volumetric of frequencies, sharp acid sounds. And of course original must be lossless and near to make a compare. Once heard and understood it more, you can feel the difference without any additional effort. Good to hear Psy Trance / Full On. For example on "Digicult - Out Of This World" album or "Ananda Shake - Inside the Sound" album.
right there you are agreeing with my view that the sound quality is not noticeable unless you use specialized equipment
regular listeners will not listen on monitor headphones
