We are in exactly the same boat DP 3.11 here too.
URS makes some cool eqs (from what i hear). I'll be loading my PB up with DP4 soon as a beta tester. They've got demos... I'm not sure if they've got AU yet.
PSP audioware has a new eq. I'm going to try that too when it hits AU.
I personally would like to see the UA stuff native for AU, latency from the card does not excite me.
Any others?
