I have a Zamp I used for awhile for driving the rear center speakers in an EX/ES setup. Quality was top notch for what I asked of the amp, and it mated well with the Parasound HCA-855 I used to drive the rest of my system. Unfortunately, I have now moved and only have a 5.1 setup at the moment and the forseeable future (no room for EX/ES). This amp would be perfect for driving a set of Paradigm Minis.
