Quote: OK, I've PM'ed feiao regarding the max Aux input voltage of the E17, and he said that 2Vrms would not be a problem for the E17.

Quote: IF the E17 shares the same amp design and architecture of the E7's, then the maximum input to AUX before it starts clipping is 1.2 Vrms (credit to NAG and his blog for the info about the E7). 

Just a thought but you could be overdriving your E17 with the Xonar output(analog). I would go the S/PDIF route if I were you.   I can't find the specs for the max input voltage for the E17 AUX, but Xonar has an output voltage of up to 2 Vrms.

Why is your headphones plugged in the AUX of E17?

Quote: Ok, thanks for the reply. But will this work with Vista32 though?

Hi, I just got the E17 last week and what a big improvement over my laptop's soundcard. My question is will this ASIO driver work with Windows Vista32 +iTunes?
