Bruin:
Easier than taking out Tommy Trojan (What's the deal wtih the horse, anyway?)
But seriously:
I would have to presume that having on on-screen display with either the 1070 or 990 to help run the system would be a big plus for your significant other. Of course, as good as the 1050 was, there's got to be better sound either way. If you are only running a two channel system (hard to tell from your mention of the Parasound amp -- are you only 2.0/2.1 or 6.1 with that as the fronts?) having Dolby Virtual would be a plus, and then there are all the other things that simplify the system and make it sound better!
Good luck!
