Hi All I'm asking for opinions on the 4700 vs the new 4800. As of today Thanksgiving weekend the 4700 is available for an unheard of $1500 as it has been selling for 1900 then 2000 and in most places still $2100. The 4800 is $2500 and there doesn;t seem to be many differences at all in features that would matter to me. I'm looking for 3 zones 1st a 5.1 set up, 2nd a 2.1 and 3rd a 2.0. The 4700 will certainly do that. The newer 4800 has 4 sub outputs which I will never go beyond 2. The amp\/preamp specs seem to be exactly the same including power output. I will use this to watch movies and to listen to the same music in three rooms simultaneously, wired. Anybody have opinions on whether it makes sense to save $600 on a 2 year old model (but brand new from Denon.) that seems like it will do for me what the new model will do, but for $2500?
