You could nicely improve your system by having your Sony 777 modified/upgraded by one of the modifiers such as Dan Wright at ModWright. It will make an INCREDIBLE difference.
Or even consider going to a modified DVP-NS9100ES. It's my understanding that that unit, when modified properly, outperforms (noticibly better) even the modded 777es AND the modded 999es that Dan has had such good experience with.
Everything else looks excellent and well balanced.
Happy Listening.
