Been though all of them.
I have two HT'S. One in my living room the other in my bedroom. My 950 was in the bedroom, the 990 is in the living room. I was patiently waiting to upgrade until the 950 died,and was out of warranty.(Then I was impatiently waiting). My plan was to buy the 997 for the living room and use the 990 in the bedroom. When the OUTLAWS reduced the price of the PR-SC886 I jumped ship. I had OUTLAW BUCKS expiring in February. I got the ONKYO shipped for under $400.00. So for a while I was on the fence again. Along with the PR-SC886 I have a Oppo BDP-83, 5 IRD mb's and a Samsung un46b6000vf. 5 in wall speakers and an OUTLAW sub,XM receiver. I now only use the bedroom HT.
So I'm back to #1,if the upgrade bug starts again when the 997 is available, because I'm not using the Living room HT which consists of:
Paradigm studio CC & 60's front,APD'S side,20's rear, SVS 16-46PC+ SUB,SMS-1,OUTLAW-7125 amp,monster HTS5100,PS-3,SONY DVP-CX995V,VUDU,SONY KDF-60XS955, various cables including OUTLAW. Berkline recliners. When I think how this system will sound with the 997 I'm #2. LOL
