The Zpre3 is well thought of around here, the Erik poster thinks it's better sounding than the Parasound P5. I had the P5 at one point and found it too compromised for the money.
Those Outlaw monoblocks look like a great option. You'll want to find out what their unity power requirements are, and if the Zpre puts out enough voltage drives them to full power.
