Hi techguy.  With those quite efficient drivers and a relatively small room I would recommend the C+, the ZS or if you can afford them, the ZSM. Unless you listen to predominantly classical orchestral works that you wish to play very loudly, I think the wattage will work for you. And these amps have an amazing sound, with detail, depth, and solidity. I think your speakers will really like them, and I'd recommend this series of amps to anyone who loves speakers that are compatible with them.

To really best explore your options, I'd recommend a call to Steve. He's the best word on what amp works best for a speaker.
