Hello storm, I don't know if you saw the youthman's video yesterday and made mention of the difference in favor of the prepro vs avr and compared the sr8015 to av7706 and the av7706 was the clear winner since the dynamics and channel separation was greater than in the sir .. if you are not going to use the internal amplifiers, why pay for them? You already had a good av I doubt you will notice improvement using the 8500 as a prepro since youthamn did the same test with the sr8015 with hardly any improvements, in your case I would have gone to the prepro av860 or avm60 that seem to be on another notch!Same here! I love these surrounds since I do not have rear surrounds and these give me an extra effect of rear sound.
I'll be comparing the 8500 Denon as a processor only to the Marantz 8805 and giving my impressions in the coming weeks. Since I do not need the amps in the 8500, I want to see if the Marantz is better in the processing department. I know the SINAD is better on the Denon but that's not as important with EQ enabled and real listening. I'll keep whichever one sounds better to my ears.
