Does anybody know if I would be able to hear the difference between lossy and lossless music on a pair of Incase Sonic headphones?
Depends on the tracks and your age.
A little background info:
I rip all my CDs to ALAC yet also convert them to 256bit AAC. The ALAC version is for archiving and high-end audio equipment while the AAC version is for my jogging iPods.
[On a side note: I wish Apple would offer a 320GB iPod Classic since all my ALAC tracks currently fill about 260GB of HD space. Would be awesome to have all my music in lossless quality with me. Best compromise I found so far are the 240GB RapidRepair iPod harddisk upgrades for the 5.5gen iPods. Anyone know of any other option like this with higher capacity?]
With all my music available to me in lossless and 256bit AAC I often do blind test to compare one against the other.
From these tests I can say that especially tracks I know well (favorite tracks) which use crisp high pitched notes e.g. from synth or violins I can tell the difference accurately. AAC tracks just sound muffled and muddy in comparison - if you know what to listen for. At one point I also tried 320bit AACs with same results.
There is value in lossless audio, especially for tracks you love and which use high crystal clear sounds where you would like to hear them in as good a quality as you can have.
But there are also tracks where differences are much harder to discern.
At least for me.
With age also your ability to hear higher pitched notes is diminishing too.
