I upgraded from the 1050 just over a month ago. There is definately a big improvement in sound quality. Most noticably, the 950/7100 is much quicker, has better soundstaging, and is much more open sounding.

Featurewise, I like the added formats. If a SACD or DVD-A player is in your future, the analog bass management feature of the 950 eliminates the deficiencies of most of the current crop of players in that regard.
