OK , but this model of XFi had 4 IC with 5 jack's ( see pic ). The XFi normal ( on PCI ) had 3 IC for front / cent+ sub / surround and 1 IC for mic input ( and 4 jack's ). At this model ( PCI-E ) who is who ?

All that 3 op-amp are compatible pin to pin with IC from Xfi board ? And for that model of XFi what IC is for what ? ( front / rear / cen + sub / side )

Which one ? What pick from AD 8599 or AD 8066 or LM 4562 ? The caps - what type and brand ? THX

The subject : Xfi Titanium Fatality Professional PCI-Express. What can change on it ? Sugestion, advice, tips & tricks ..... Thank you.
