This is very confusing.......what do you mean by "power"?
The USB interface is undeniably superior to any S/PDIF or TOSLINK interface because it takes the embedded clock out of the data stream. Unless you have some device that is interfering with the bus that causes latency problems when using the E-MU driver--and that would present itself as pops, clicks, or dropouts--the USB transfer is superior.
And why would you turn down the level in Foobar? It can't do anything positive--as far as I have been able to determine, doing so involves manipulation of the audio data.
