I will keep the Toslink all the way to the trunk and connect to the Zapco processor. It is controllable via PC and USB cable and is very nice. It accepts multiple digital inputs and outputs balanced stereo to the amps.

To: galvitron have you thought about which cpu to get yet seeing as this uses a LGA775 socket? I use the E6700 and it get's hot under pressure not even the 3-fans can cool it down under 90deg's in the summer's heat winter is a different story..
If you don't get it the first time around, go get seconds..
