I just stumbled across the audio midi app in my Mac. I changed the audio format from 44khz to 96khz and the channel to 2ch 32 bit float. I immediately noticed a dramatic change in the audio. Basically, the music track I was listening to seemed to become deeper/drop and the soundstage dropped. (I'm not sure of the correct audiophile terms). However, when I played a flac file the change was less dramatic. Is this kind of playback closer to the 'correct' way the track should sound? Where possible I play tracks >320 kps and my speakers are fairly good but I am confused about sample rates. Most of my itunes have a sample rate of 44khz. Should I try and get music files from now on with a higher sample rate?
