No, the built in music player with allow playback of any resolution provided you have an idevice dac that's capable of that resolution. It's the internal dac that's the limiting factor. Even using flac player, the internal dac is still limiting high res playback and it will get downsampled.
So according to the guy below, it will all be down-sampled to 16/44.1? So high res .flac converted to AIFF should be good enough on a iDevice with no quality difference from playing from an iOS flac player?
There are NO iPods at the moment that will play 24/96... the hardware does not support it, it's all down sampled to 16/44.1
The current Classic's can decode 24/48 but still down sample to 16/44.1 to play.
There is talk on here about the iPad 2 playing 24/96 through the Camera Connection Kit but the songs have to be encoded as AIFF and manually transfered to the iPad, iTunes will not sync the files...
