I bought the Onkyo 608 in April. Had the Rotel RSX1067 and found it to laidback for movies, did not have the oomph or excitement,set up was a pain inputs were limited so was the HDMI. Bought the Onkyo after listening to the Denon 1910 and a Marantz. The Onkyo was great with movies, and the processing was fantastic, I can basically control all sources, even DSTV with the Onkyo. Haven;t done a comparison on the upscaling but have seen difference on some channels
CONS
It is NOT the most musical receiver (this is where the Rotel shone),
no back lit remote
no inputs for power amps (took this into account when I bought it)
PROS
Fantastic processing and speed
Runs cool
Great set up - only adjusted the centre speaker
