Does anyone have any experience with the Pioneer 711 or 811 (I assume both put out the same actual power vs. advertised power which is 67W for the 811) I will most likely be upgrading to the Studio 100/80 or Monitor 9's for the front. I will also be getting smaller bookselves of the same series for the back, but I assume they dont need as much power as the mains anyway. So do you think this receiver will be powerfull enough to drive them or would you go with another receiver? There isnt a single place where I live that carries both, so I can't really try it out for myself. Thanks.
