I dont find the a35 sharper at all when I tested, all I noticed in difference was the reon options to reduce noise, I turn two of them on and leave block noise off. But sharpness I dont know how you see a bit better sharpness, unless you have all the filters on. Im also assuming you guys tried firmware 2.7 where most of us noticed a better picture.
Of course you could just turn edge enhancement on to enhance the sharpness, 1 does a great job without adding any artifical detail. The xa2 also passes all dve tests while the A35 had the odd issue. I dont doubt the onkyo is every bit as good as the xa2, what I do question is how the same hardware and the reon is producing a sharper picture. Especially when someone claimed the onkyo was the same as xa2 on 1080p 60hz but on 24fps somehow the onkyo was sharper. Again im wondering how changing framerate made the picture sharper.
