I beleive you downgraded when you went from a 7000 to a 7700 as the picture and cd sound quality were better on the 7000.Having said that...the 9000 es is better sounding on cd,sacd sounds better than 2k cd only units,and if you can take advantage of the progressive scan on the 9000,you will have a much better picture.The 9000 has 2 channel sacd only but the new dvp-ns900v has multi channel sacd and progressive scan as noted by danielk141.
