When you take the amps out of the 4520, there should be lots of open space but the 8801 is jam packed full!
While I have read of several here with issues on their 4520 needing repairs already, I don't recall reading any on the 8801 thread with major problems - just issues with software that are slowly being resolved with updates.
I am drawn to the Marantz as I am anal about design and build quality while it will make little or no difference in sound with my system. Even though Denon and Marantz fall under the same parent corporation, I would hope at least for a while that Marantz can maintain their reliability record. I have had absolutely flawless equipment since purchasing the Pioneer Elite products over the years and want to keep that up with my next purchase as I have zero tolerance for stuff that breaks!!
I don't know if the Asia-Pac units are any better built, but since I am a statistician, it matters to be clear.
Members with dud units then to be more vocal, so you may here more about spoilt Denons, but more importantly, the INCIDENCE of spoilt units will be higher for any unit which sells more units. But the INCIDENCE RATE can be the same. Sell more units, and you will get more units with defects.
I think at the price of the 8801, which is at least $2000 more - $600 + 1-2k more for amps, you won't see the same take up rate for the 8801.
People call the 8801 $600 or so more, that's not accurate, since you need to buy power amps for any sound. For the Denon you are good to go if you aren't particular about amps.
