I like the improved sounds of the HD tracks, but they will not play on my Apple nanno for some reason.
AFAIK all iPods can only support up to CD quality (16 bit / 44.1khz) so if you've put the 24/96 files directly from HDTracks onto your Nano, it won't be able to play them. You have to convert the files to CD quality first.
I'm assuming that includes iPads and iPhones as well... I was up till midnight trying to import the tracks from iTunes with no luck so still no DT12 for me today
(I bought the ALAC format...).
Their FAQ says to:
1. Highlight the tracks in itunes that you would like to put on your iPhone/iPod.
2. Go to File > Create New Version > Create iPod or iPhone Version
3. Take the new files and transfer those onto your iPhone/iPod.
4. Sync music onto iPhone/iPod
But that option (and another I can't recall) was grayed out and the only one I could choose was WAV... Which I can't understand. I thought the apple lossless format would be the best choice to download from HD tracks...
