I use Cary 805Cs with my wilson watt puppy 7s. My listening chair is 7 feet from the speakers and I listen at 70 to 80 db volumes(Rock and folk music). I have no problem with the Carys low power and the combination can also fill the house with wonderful music. Back in the day before making the purchase I talked to Peter Mcgrath at the Rocky Mountain Audio Fest. He recommended the combination and stated that Wilson had previously used the combination at a prior audio show.
My recommendation for the Wilsons would be a high quality tube amp.
