I agree totally with Aolmrd1241, All this time of following this thread, I thought a transport was being used, Now that I have found out that it is not, this gives me a different perspective on the Imperical ODSE and other Dacs on this thread, as a matter of fact, The APL Dac that matt said sounded a little hard on the treble likly exsposed the use of a inferior cable like usb!!, I understand the Dac may need further burned in, However, All dacs sound incredibly better with a quality Digital cable, and then running quality balanced analog interconnects from the dac to the pre-amp or direct to amplifier!
