My partner and I recently auditiond the PIONEER AX10i-s and DENON AVC-A1SR. We heard them with CD for stereo, DVD (Mission Impossible II flamenco scene 5.1, Start Wars I - race scene THX Ultra2 Cinema). The source was the Pioneer 757 with i-link for the Pioneer and 5 cables for the Denon. We independently found the Pioneer rather too "bright", and even over a short time, found it a strain to listen relative to the Denon. The Denon sounded warmer, and the only thing we could fault it for was that relative to the Pioneer, the commentary (by the two headed lizard) in the Star Wars race sciene, seemed a little muffled with the Denon relative to the Pioneer. In terms of gadgets, bells, whistles and overall connectivity (i-link allows more flexibility perhaps), I would have gone for the Pioneer, but having heard the "warmth" of the Denon, I feel there's no comparision. Note the feed was 5 cables no i-link. I spoke to Pioneer about this and they acknowledge that the 10i-S is brighter than the AX10 original. They seem to think it is designed this way so perhaps I am alone in not liking it??
