Has anyone matched a pair of Zu Omens (2010 no upgrades) with a Peachtree Grand X1 amp?

Has anyone matched a pair of Zu Omens speakers (2010 , no upgrades) with a Peachtree Grand Intergrated X-1 amp? I've been running my Omens with a NuPrime IDA-8 amp but came into the Peachtree X-1 and couldn't resist. I wired direct to my IMac via USB cable. I'm Running J. Rivers 
any insight or suggestions are appreciated for a new comer just getting back into music again.
