My Klipsch RF-63/RC-64/RS-35 system also has sub 3ohms dips and my Acurus A200FIVE has no problems at all handling this job. My previous B&K amps also were up to the task and passed with flying colors. I do think the Parasound is probably an overall better amp than the Sunfire but both will do just fine.
I do have another Acurus A200FIVE that I am going to sell if that may be an option.
Maybe ask your same question over at the Klipsch forum. Gobs of RF-7 owners over there powering them with many different amps.
