I have the Integra 9.1. I am contemplating the purchase of the upgrade package. Can someone comment on the sound differences from this upgrade? I am trying to determine if it is worth doing the upgrade at this time.
I upgraded my 989 a few months ago while Onkyo was offering the 200.00 discount along with another 50.00 discount if you already purchased the DPL2/DTS-ES upgrade.
For me it was money well spent. I use THX-Ultra2 mode on all my DD 5.1 sources and I really enjoy the added surrounds. The upgrade also fixed the DD 5.1 dropouts that I was having on Discovery HD and a few times on 5.1 moves on HBO.
