Modest SS amplifier for secondary system

I am looking to setup another smaller system based around a pair of  PSB Stratus Mini Gen II speakers (4 ohm load) on appropriate stands.  I'm looking over the used market and would like to keep the price under 1K.  My minimum power requirement is 100 WPC into 8 ohms. This system will be used for near-field listening in a modestsized room that is acoustically fairly dead.  Perfect for mini monitors!  I'm actually
quite surprised how low these little guys go. Imaging and soundstage is remarkablefor speakers this size and at this price point.

My short list for consideration is as follows:

Anthem MC-2 Series II
Parasound Halo A23
Parasound HCA-1500A 
Aragon 2004 MKII
Classe' Audio CA-100

I am a little gun shy regarding the Aragon. I've had issues in the past with both Aragon and B&K amps exhibiting mechanical transformer noise. Other amps with toroidal transformers did not have this issue plugged into the same power source and using the same source. The Classe Audio CA-100 is a little light in the power department, but I do have a soft spot for legacy Classe gear. I have a Classe Audio "Fifteen" that I absolutely LOVE that is in service in another system.

I have an Anthem Statement D2v as the heart of my theater system, I think highly of Anthem gear and would certainly consider one of their MCA  2-channel amps. I also respect most of the John Curl designed Parasound offerings; one of them powers my center channel speaker.

I have listened to the Stratus Minis with my Classe "Fifteen" with excellent results. I also
tried an older Hafler DH series amp that quickly left me missing the Classe. I have more
than one preamp option in my bag of tricks, for now I'd like to focus on final amplification.

Any thoughts or suggestions?
