I was thinking of buying either the Onkyo TX-SR600 or the Pioneer VSX-D811S. I am leaning toward the 811 because it has pre outs so I can add an amp later if I wanted to. My question is: Would I really want to add an amp to the 811? I mean, If I spend $1000 or so on an amp later down the road, is the 811 really what i want to process the DD and DTS sources. At this price range, are the pre outs just for show? Am I right to think that the decoding performance of the 811 is on par with higher level receivers, and the only reason that the 811 is cheap is because the amps are cheaper. True? Isn't processing pretty much the same for the most part? P.J.
