I'm still trying to understand these devices. DAC/amp with on board storage....
....what player do you have it paired with?
I am still not sure if the on board storage can be accessed by an iDevice using the Onkyo HD player as I have yet to buy the Samsung mSATA 1TB SSD and so have not tried.
Besides the iDevices, I have used my AK120S and 240 via optical which plays at 24/192......................
At present listening from the PC using JRiver MC20..............and with an Ultrabook when traveling, the storage will help here!
