I completely missed gmahler2u's reply :P. So this setup quite simple. Basically the Resonessence Labs Herus uses the ESS ES9010-2M DAC which works with regular USB Audio (I was trying the iMac and MacAir earlier) but seems to work with the iPad via the Camera Connection Kit (CCK) accessory. Audio plays out fine and a step up from the iPads' headphone out. I need to burn in and play with it a little more.
I've not tried the Audioquest Dragonfly therefore can't really do a comparison there. However from my iMac/MacAir, I have managed to play DSD native (via Audirvana Plus player).
Thank you Sean
