I can't caompare the Denon 560 to the Denon 710, but in the last week got both the Denon 560 and the Klipsch S4. I personally prefer the Denon's. They just have an over all better sound to my ears. Of course these are both new nad have not been burned in, so thinkgs could change. Over the past few days I still prefer the Denond. Not to mention the Denons are built tough.
I agree with the above post, the Denons do seem to have more bass.
