I could not find anything on the description of the A100 that it uses better capacitors. On the website, it states "a special edition block condenser" For all we know, they could have encased it in lead and polished it a gloss black. That way, we would all know it would be much better because it would weigh more and it would be shiny when we took the lid off. Seriously though, unless someone actually has one in hand and can verify the components, there would be little that Denon would actually have to do make the statement "special edition" true, and it would not necessitate better components. Also, if you look at the back of the A100 on Crutchfield's site, it has the same power supply rating as the 4311. I'm not trying to knock the A100 and I love my 4311 (after only 2 days of use), but I just wouldn't want those buying the A100 for reasons other than aesthetics or the additional warranty to get burned by getting the same internal components as the 4311.
