Is the STX able to send sound / output to multiple outputs at once? I would like to be able to send a signal to a Behringer A500 to power some Buttkickers and, at the same time, send sound to either an AV receiver (to listen through a 5.1 speaker setup) or to a JDS Labs Objective 2 amp (to listen to through headphones). Could I send different signals through different outputs (e.g., send music to headphones and game through the 5.1 speakers?
Also, do I even need to use the O2 amp? I'm using Beyerdynamicz DT 990 600 ohm headphones.
Currently, I'm running mutil-channel analog for games from my on board MB (Asus Maximus V Gene) to my AV Receiver and 5.1 speakers, and sending music to an Asus U3 USB soundcard to the O2 Amp and the DT 990's (or running everything to the U3 and Dolby Headphone if my wife is trying to sleep).
Will the STX will produce much better music quality than the U3 or about the same?
Thanks in advance!!!
