I'd go with the Atlas in a heartbeat. I never worry about watts as it's just a measurement. Get the right sounding amp. The Atlas or Ayre's etc... should be able drive nearly anything you can throw at it. I've heard the Ayre mono blocks drive speakers that drink power..... The new Ayre MX-R Twenty's are to kill for. I have heard them with a few different speakers and they are as good as any amps I've heard.
